.Sh NAME
.Nm bsd.port.mk
.Nd ports tree master Makefile fragment
.Sh SYNOPSIS
.Fd .include <bsd.port.mk>
.Sh DESCRIPTION
.Nm
holds all the standard routines used by the ports tree.
Some variables and targets are for its internal use only.
The rest is documented here.
.Pp
.Nm
also uses quite a few helper scripts.
Those live under
.Pa ${PORTSDIR}/infrastructure/bin ,
and they do have manpages under
.Pa ${PORTSDIR}/infrastructure/man .
.Pp
Other
.Bx
variants, as well as older versions of
.Nm bsd.port.mk ,
include other targets and variables.
Conversion methods are outlined here.
.Pp
Most variables and targets are documented, with very few exceptions.
.Pp
This documentation covers the current targets, variables and paths used by
.Nm bsd.port.mk .
There is a separate section covering the fake framework, a section
explaining flavors and multi-packages, and a section covering
the generation of package information.
.Pp
It ends with sections on obsolete constructs that a porter may need
when converting from other ports systems.
.Pp
Binary package details are mostly covered in
.Xr pkg_create 1
for the packing-list details,
and in
.Xr pkg_add 1
for the installation semantics.
.Pp
Selected common user activity such as the building of every package in
the system is covered by
.Xr ports 7
instead.
.Xr packages 7
provides an overview of the result.
.Sh TARGETS
.Bl -tag -width do-configure
.It Ar {build,run,all,test}-dir-depends
Print all dependencies for a port in order to build it, run it, build and
run it, or to run regression tests.
The output is formatted as package specification pairs, in a form suitable
for
.Xr tsort 1 .
.It Ar full-{build,run,all}-depends
Print all dependencies a package depends upon for building, running,
or both, as a list of package names.
.It Ar {build,lib,test,run}-depends-list
Print a list of first level package specifications a port depends as
build dependencies, library dependencies, test dependencies or
run dependencies.
.It Ar print-{build,run}-depends
User convenience target that displays the result of
.Ar full-{build,run}-depends
in a more readable way.
.It Ar {pre,do,post}-*
Most standard targets can be specialized according to a given port's needs.
If defined,
the
.Ar pre-*
hook will be invoked before running the normal action;
the
.Ar do-*
hook will be invoked instead of the normal action;
the
.Ar post-*
hook will be invoked after the normal action.
Specialization hooks exist for
.Ar build ,
.Ar configure ,
.Ar distpatch ,
.Ar extract ,
.Ar fake ,
.Ar install ,
.Ar patch ,
.Ar test .
See individual targets for exceptions.
.It Ar addsum
Complete the ${CHECKSUM_FILE} record of checksums with files that have been
added since
.Ar makesum .
Complain if anything does not match.
.It Ar all-lib-depends-args
Process the full
.Ev LIB_DEPENDS
list into a form suitable for
.Xr pkg_create 1 ,
see
.Ar print-package-args .
.It Ar build , Ar all
Default target.
Build the port.
Essentially invoke
.Bd -literal
env -i ${MAKE_ENV} ${MAKE_PROGRAM} ${MAKE_FLAGS} \e
	-f ${MAKE_FILE} ${ALL_TARGET}
.Ed
.It Ar build-depends
Verify the ports mentioned in
.Ev BUILD_DEPENDS ,
by checking the corresponding packages are actually installed,
and install the missing ports by recursing through the ports tree.
Deprecated, see
.Ar prepare .
.It Ar check-register
Introspection target.
Verify from the ports tree, without building anything, that the current
subpackage will register okay
.Po
see
.Ev PLIST_DB
.Pc .
.It Ar check-register-all
Apply
.Ar check-register
to all subpackages of the current port.
.It Ar checkpatch
Debugging version of the
.Ar patch
target that simulates invoking
.Xr patch 1 .
.It Ar checksum
Check distribution archives and distribution patches control sum against
the results recorded in ${CHECKSUM_FILE},
using the message digest (checksum) utilities listed in ${PREFERRED_CIPHERS}.
All the files needed to recreate a port should be in ${CHECKSUMFILES} and
checksummed.
Invoking
.Ar checksum
with
.Ev REFETCH Ns = Ns Cm true
will try to fetch a version with the correct checksum from the
.Ox
main archive site in the case of a checksum mismatch.
.Ev NO_CHECKSUM
can be used to avoid all checksumming steps.
.It Ar clean
Clean ports contents.
By default, it will clean the work directory.
It can be invoked as
make clean='[depends build bulk work fake flavors dist install sub package
packages plist]'.
.Bl -tag -width packages
.It Va work
Clean work directory.
.It Va bulk
Clean bulk cookie.
.It Va build
Clean the
.Va WRKBUILD
directory (only useful if
.Va SEPARATE_BUILD
is set).
.It Va depends
Recurse into dependencies.
.It Va dist
Clean distribution files.
.It Va fake
Clean fake installation directory.
.It Va flavors
Clean all work directories.
.It Va install
Uninstall package.
.It Va package
Remove all copies of package file.
.It Va plist
Remove registered packing lists of all subpackages.
.It Va sub
With
.Va install
or
.Va package ,
clean subpackages as well.
.It Va packages
Shorthand for `sub package'.
.It Va all
Shorthand for `work flavors packages plist'.
.El
.It Ar clean-depends
Short hand for make clean=depends.
.It Ar configure
Configure the port.
Might be a void operation.
Unless overridden, configure creates the ${WRKBUILD}
directory (see SEPARATE_BUILD),
and runs whatever configuration methods are recorded in
.Ev CONFIGURE_STYLE .
.It Ar depends
Check all the port's dependencies, that is:
.Ar build-depends ,
.Ar lib-depends ,
.Ar run-depends ,
.Ar test-depends .
.It Ar describe
Prints a one-line index entry of the port, suitable for
.Pa ${PORTSDIR}/INDEX .
.It Ar distclean
Short-hand for make clean=dist.
.It Ar distpatch
Apply distribution patches only.
See
.Ar patch
and
.Ev PATCH_CASES
for details.
.It Ar dump-vars
Dump the values of all relevant variables in a port, prepended with the
port's FULLPKGPATH.
.It Ar extract
Extract the distribution files under
.Pa ${WRKDIR}
(but see
.Ev EXTRACT_ONLY
and
.Ev NO_DEPENDS ).
Refer to
.Ev EXTRACT_CASES
for a complete description.
Do not use
.Ar pre-extract
and
.Ar do-extract
hooks.
.It Ar fake
Do a fake port installation, that is, simulate the port installation under
${WRKINST}.
There is no
.Ar do-fake
and
.Ar post-fake
hooks.
.Ar fake
actually uses
.Ar pre-fake ,
.Ar pre-install ,
.Ar do-install
and
.Ar post-install .
Override
.Ar pre-install ,
.Ar do-install ,
or
.Ar post-install
to change behavior.
Do not touch
.Ar pre-fake
unless you really know what you are doing.
Described in a separate section below
.Po
.Qq THE FAKE FRAMEWORK
.Pc .
.It Ar fake-wantlib-args
Check
.Ev WANTLIB
against the list of installed packages and libraries in the ports tree.
See
.Ar print-package-args .
.It Ar fetch
Fetch the distribution files and patchfiles, using ${FETCH_CMD}.
Each file of the
.Ev DISTFILES
and
.Ev PATCHFILES
lists is retrieved, if necessary, from the list of sites in
.Ev MASTER_SITES .
.Pp
If a filename ends with a
.Sq :0
to
.Sq :9
extension, it will be retrieved from
.Ev MASTER_SITES0
to
.Ev MASTER_SITES9
instead.
After stripping that extension if necessary,
if the entry parses as
.Sq Ar filename Ns { Ns Ar url Ns } Ns Ar sufx
it will be fetched as
.Ar url Ns Ar sufx
instead, yet still stored as
.Ar filename Ns Ar sufx .
.Pp
Transfers in progress will be stored as
.Ar filenamesufx.part .
.Pp
The ports framework uses
.Pa ${DISTDIR}/${DIST_SUBDIR}
(aliased to
.Pa ${FULLDISTDIR} )
to cache the ports distribution files and patch files.
Note that this framework is also used by mirroring scripts,
which will also retrieve
.Ev SUPDISTFILES ,
to fill with supplementary distribution files which are not needed for
every configuration.
.Pp
Note that fetching a significant number of distfiles, or fetching all distfiles
relevant to a port and dependencies is better accomplished using
.Xr dpb 1
with the
.Fl F
option.
.Pp
Use of
.Ar {pre,do,post}-fetch
hooks is forbidden, as this would make mirroring of distfiles very complicated.
See
.Ev CHECKSUMFILES ,
.Ev CDROM_SITE ,
.Ev DISTDIR ,
.Ev DISTFILES ,
.Ev DIST_SUBDIR ,
.Ev FETCH_CMD ,
.Ev FETCH_MANUALLY ,
.Ev FETCH_SYMLINK_DISTFILES ,
.Ev FULLDISTDIR ,
.Ev MAKESUMFILES ,
.Ev MASTER_SITES ,
.Ev MASTER_SITES0 , ... ,
.Ev MASTER_SITES9 ,
.Ev PATCHFILES ,
.Ev SUPDISTFILES ,
.Ev REFETCH .
.It Ar fetch-all
also fetches
.Ev SUPDISTFILES ,
for use with e.g.,
.Ar makesum .
.It Ar index
Top-level target, see
.Xr ports 7 .
.It Ar install
Install the package after building.
See the description of
.Qq THE FAKE FRAMEWORK
for the non-intuitive details of the way
.Ar {pre,do,post}-install
hooks are actually used by the ports tree.
.It Ar install-all
Install all packages in a multi-packages port.
.It Ar lib-depends
Verify that the library dependencies a port needs are actually there,
by checking the library specifications.
.It Ar lib-depends-args
Filter
.Ev LIB_DEPENDS
to keep only entries required by
.Ev WANTLIB ,
and output a list of dependencies suitable for
.Xr pkg_create 1 ,
see
.Ar print-package-args .
.It Ar lib-depends-check
Verify that the
.Ev LIB_DEPENDS
and
.Ev WANTLIB
are accurate for the port.
See
.Ar port-lib-depends-check ,
which is quicker.
.It Ar license-check
Check that
.Ev PERMIT_PACKAGE_*
settings match:
if any dependency has a more restrictive setting, warn about it.
This warning is advisory, because the automated license checking cannot
figure out which ports were used only for building and did not taint
the current port.
.It Ar link-categories
Create symbolic links in other directories that correspond to the port's
.Ev CATEGORIES .
Note that this does not affect bulk package building, since those links
don't appear in the upper-level Makefiles.
See also
.Ar unlink-categories .
.It Ar lock
Manually obtain a lock on a given directory.
Output must be used to update environment variables.
The lock can be released with
.Ar unlock .
Seldom used, see
.Xr ports 7
for details.
.It Ar makesum
Create the ${CHECKSUM_FILE} list of recorded checksums by running the
cryptographic fingerprint sha256 on ${MAKESUMFILES}.
That normally includes ${DISTFILES}, ${SUPDISTFILES} and ${PATCHFILES}.
.Ev NO_CHECKSUM
can be used to avoid all checksumming steps.
.It Ar manpages-check
Verify that
.Xr makewhatis 8
can do a correct job with the port's manpages.
.It Ar mirror-maker
Top-level target, see
.Xr mirroring-ports 7 .
.It Ar mirror-maker-fetch
Debug target: generate the
.Ar mirror-maker
makefile fragment and use it
to fetch files, see
.Xr mirroring-ports 7 .
.It Ar no-lib-depends-args
Degenerate form of
.Ar lib-depends-args
that does not do anthing.
See
.Ar print-package-args .
.It Ar no-wantlib-args
Degenerate form of
.Ar wantlib-args
that does not do anything.
See
.Ar print-package-args .
.It Ar package
Build a port package (or packages in a
.Ev MULTI_PACKAGES
case) from the fake installation.
Involves creating packaging information from templates
(see
.Ev COMMENT ,
.Ev SUBST_VARS
among others) and invoking
.Xr pkg_create 1
for each package in the
.Ev MULTI_PACKAGES
list.
If the repository already contains up-to-date packages, they are not rebuilt.
If PLIST_DB is set, the resulting packaging information is compared
with existing stuff, and saved if new, with loud complaints if it changed
without a REVISION bump.
Arch-independent packages are created in ${PACKAGE_REPOSITORY}/no-arch,
and copied into ${PACKAGE_REPOSITORY}/${MACHINE_ARCH}/all as needed.
If ${PERMIT_PACKAGE_FTP} is set to
.Sq Yes ,
copies built packages into ${PACKAGE_REPOSITORY}/${MACHINE_ARCH}/ftp, using
hard links if possible.
If ${PERMIT_PACKAGE_CDROM} is set to
.Sq Yes ,
copies built packages into ${PACKAGE_REPOSITORY}/${MACHINE_ARCH}/cdrom, using
hard links if possible.
.It Ar patch
Apply distribution and
.Ox
specific patches.
Because of historical accident,
.Ar patch
does not follow the exact same scheme other standard targets do.
Namely,
.Ar patch
invokes
.Ar pre-patch
(if defined),
.Ar do-patch ,
and
.Ar post-patch ,
but the default
.Ar do-patch
target invokes
.Ar distpatch
directly.
So, if the
.Ar do-patch
target is overridden, it should still begin by calling
make distpatch, before applying
.Ox
specific patches.
Accordingly, the exact sequence of hooks is:
.Ar pre-patch ,
.Ar do-distpatch ,
.Ar post-distpatch ,
.Ar do-patch ,
.Ar post-patch .
If
.Pa ${PATCHDIR}
exists, the files described under
.Ev PATCH_LIST
will be applied under
.Ev WRKDIST .
See also
.Ev REORDER_DEPENDENCIES
for possible
.Ar post-patch
clean-up.
.It Ar peek-ftp
Connect to the first site in
.Ev MASTER_SITES ,
in the right directory, and leaves user at
.Xr ftp 1 Ns 's
prompt.
.It Ar pkglocatedb
Top-level target, see
.Xr ports 7 .
.It Ar port-lib-depends-check
Verify that the
.Ev LIB_DEPENDS
and
.Ev WANTLIB
hold all shared libraries used for every package in the port.
See
.Xr library-specs 7 .
This makes use of
.Ar print-plist-with-depends
to avoid actually building the packages, it only needs the
completion of the
.Ar fake
stage, and thus is quicker than
.Ar lib-depends-check ,
unless you already have all binary packages.
.It Ar port-wantlib-args
Resolve
.Ev WANTLIB
against the ports tree itself and system libraries, without looking at built
or installed packages, and writes a list of options suitable for
.Xr pkg-create 1 .
See
.Ar print-package-args .
.It Ar prepare
Prepare a port for building, by checking and installing all required
dependencies, constructed from
.Ev LIB_DEPENDS
and
.Ev BUILD_DEPENDS .
In
.Ev MULTI_PACKAGES
setups,
see
.Qq Flavors and multi-packages .
.It Ar print-package-args
Print all dependency-related information that will be passed as parameters
to
.Xr pkg_create 1 ,
\&.e.g.,
.Fl W Ar wantlib
and
.Fl P Ar depends
lines.
.Pp
Those parameters are generated by
.Ar run-depends-args
for
.Ev RUN_DEPENDENCIES
handling, a form of
.Ar lib-depends-args
for
.Ev LIB_DEPENDS
and
.Ev WANTLIB
interaction,
and a form of
.Ar wantlib-args
for
.Ev WANTLIB
resolution.
.Pp
Variables
.Ev lib_depends_args
and
.Ev wantlib_args
control the exact behavior:
.Ev lib_depends_args
is normally set to
.Ar lib-depends-args ,
but will be set to
.Ar all-lib-depends-args
by
.Ar port-lib-depends-check ,
in order to have access to the full list of LIB_DEPENDS for figuring
out missing WANTLIB.
.Ev wantlib_args
is normally set to
.Ar wantlib-args
but it may be set to
.Ar port-wantlib-args
for introspection purposes,
to
.Ar fake-wantlib-args
to avoid some checks, or to
.Ar no-wantlib-args
to avoid expensive WANTLIB checks entirely.
.It Ar print-update-signature
Print the update signature, as computed using information from the ports tree,
in the same format used for
.Xr pkg_info 1
.Fl S .
.It Ar print-plist
Generate and print a package packing-list from the static information
present in the port.
.It Ar print-plist-all
Iterate over
.Ar print-plist
for all subpackages in a given port.
.It Ar print-plist-all-with-depends
Iterate over
.Ar print-plist-with-depends
for all subpackages in a given port.
.It Ar print-plist-contents
Generate and print package contents from the static information
present in the port.
In contrast with
.Ar print-plist ,
the package contents only consists of files, all tagged with category
markers such as @file.
See
.Xr pkg_create 1 .
.It Ar print-plist-libs
Generate and print the list of static and dynamic libraries present in the port.
See
.Xr pkg_create 1 .
.It Ar print-plist-libs-with-depends
Like
.Ar print-plist-libs ,
but slower.
It also handles
.Ev LIB_DEPENDS ,
.Ev RUN_DEPENDS ,
and
.Ev WANTLIB ,
so that the packing-list has complete dependency information.
.It Ar print-plist-with-depends
Like
.Ar print-plist ,
but slower.
It also handles
.Ev LIB_DEPENDS ,
.Ev RUN_DEPENDS ,
and
.Ev WANTLIB ,
so that the packing-list is complete.
.It Ar rebuild
Force rebuild of the port.
.It Ar test
Run regression tests for the port.
Essentially depend on a correct build and invoke
.Bd -literal
env -i ${MAKE_ENV} ${MAKE_PROGRAM} ${ALL_TEST_FLAGS} \e
	-f ${MAKE_FILE} ${TEST_TARGET} ${TEST_LOG}
.Ed
.Pp
If a port needs some other ports installed to run regression tests,
use
.Ev TEST_DEPENDS .
If a port needs special configuration or build options to enable regression
testing, define a
.Sq test
.Ev FLAVOR .
.It Ar test-depends
Verify packages needed for regression tests, using the same scheme as
.Ar build-depends .
Only invoked when regression tests are run, or explicitly through
.Ar depends .
.It Ar reinstall
Force reinstallation of a port, by first cleaning the old installation.
Seldom needed, as
.Ar update
will often do the right thing.
.It Ar repackage
Rebuild the packages of a port after removing existing packages.
.It Ar run-depends
Verify the ports mentioned in
.Ev RUN_DEPENDS ,
by checking the corresponding packages are actually installed,
and install the missing ports by recursing through the ports tree.
Invoked right before installing the package.
.It Ar run-depends-args
Process
.Ev RUN_DEPENDS
and outputs a list of dependencies suitable for
.Xr pkg_create 1 ,
see
.Ar print-package-args .
.It Ar show
Invoked as make show=name, show the contents of ${name}.
Invoked as make show="name1 name2 ...",
show the contents of ${name1} ${name2} ...,
one variable value per line.
Mostly used from recursive makes, or to know the contents of another
port's variables without guessing wrongly.
.It Ar show-fake-size
Print the size of ${WRKINST}.
Used by some options of
.Xr dpb 1 ,
suitable for
.Ev BULK_TARGETS .
.It Ar show-prepare-results
Print the list of actual installed packages found out by
.Ar prepare .
.It Ar show-prepare-test-results
Print the list of actual installed packages found out by
.Ar prepare
and
.Ar test-depends .
.It Ar show-required-by
Print the list of
.Xr pkgpath 7
for all ports that will be affected by the
current port changing.
Works by walking the list of dependencies, in reverse.
.It Ar show-run-depends
Print all running dependencies for a port, one per-line, without duplicates.
.It Ar subpackage
Build a port package.
Exactly like
.Ar package ,
but affects only one single subpackage in multi-packages ports.
.It Ar show-size
Prints the size of the work directory.
Used by some options of
.Xr dpb 1 ,
suitable for
.Ev BULK_TARGETS .
.It Ar subupdate
Update an existing installation to a newer package, exactly
like
.Ar update ,
but affects only one single subpackage in multi-packages ports.
.It Ar unlink-categories
Remove symbolic links in other directories that correspond to the port's
.Ev CATEGORIES .
See also
.Ar link-categories .
.It Ar unlock
Manually release a lock on a given directory.
See
.Ar lock .
.It Ar update-patches
Create or update patches for a port, using
.Xr update-patches 1 ,
which invokes
.Xr diff 1
between
.Pa file
and
.Pa file.orig ,
based on
.Pa file.orig
existence.
In order to generate a patch, the original file needs to be named
.Pa file.orig
and
.Pa file
edited.
After the target is invoked, the patches are placed under the
patches/ directory.
It moves existing patches from
.Pa patch-file
to
.Pa patch-file.orig
.It Ar update
Update an existing installation to a newer package:
scan the installation for a package with the same
.Ev FULLPKGPATH ,
and update it using
.Sq pkg_add -r
if a newer package is available.
In multi-packages ports, all relevant packages are updated.
See
.Ev UPDATE_COOKIES_DIR
and
.Ev FORCE_UPDATE
as well.
.It Ar update-or-install
Update an installed package or perform a fresh installation,
by using
.Sq pkg_add -r .
Handles one single package in multi-packages ports.
See
.Ev UPDATE_COOKIES_DIR
and
.Ev FORCE_UPDATE
as well.
.It Ar update-or-install-all
Update installed packages or perform a fresh installation,
by using
.Sq pkg_add -r .
Handles all packages in multi-packages ports.
See
.Ev UPDATE_COOKIES_DIR
and
.Ev FORCE_UPDATE
as well.
.It Ar update-plist
Update the packing lists for a port, using the fake installation and the
existing packing lists.
.Ar update-plist
should produce mostly correct
.Pa PLIST ,
.Pa PFRAG.shared
and
.Pa PFRAG.no-shared
files, handling shared libraries, GNU
.Xr info 1
files, setuid files, and empty directories.
It moves existing files to
.Pa PLIST.orig ,
.Pa PFRAG.shared.orig
and
.Pa PFRAG.no-shared.orig .
If the generated lists include files and directories that shouldn't be
included, comment these like this:
.Bd -literal
@comment unwanted-file
@comment unwanted-dir/
.Ed
.Pp
Subsequent calls to
.Ar update-plist
will automatically recognize and handle such lines correctly.
.Pp
.Ar update-plist
may not handle flavor and multi-packages situations correctly yet, so beware.
.It Ar verbose-show
Similar to
.Ar show ,
except that it prefixes each value with the variable name, e.g.
.Li VAR=value .
Also note that it does not show undefined variables, contrary to
.Ar show
which outputs blank lines for these.
.It Ar wantlib-args
Call
.Ar port-wantlib-args
and
.Ar fake-wantlib-args
and compare the results, errors out in case of discrepancies.
See
.Ar print-package-args .
.El
.Sh VARIABLES
Note that some variables are marked as
.Sq User-settings ,
which means that individual ports should not modify them,
and that some variables are marked as
.Sq read-only ,
which means that they shouldn't ever be changed.
In a
.Ev MULTI_PACKAGES
setup, some variables have settings specific to a given subpackage.
See
.Qq Flavors and multi-packages .
.Bl -tag -width MASTER_SITES
.It Ev show
Invoked as make show=name, show the contents of ${name}.
Invoked as make show="name1 name2 ...", show the contents of
${name1} ${name2} ...,
one variable value per line.
.It Ev ALL_FAKE_FLAGS
Flags passed to ${MAKE} invocations during the fake process.
Equals
.Li ${MAKE_FLAGS} ${DESTDIRNAME}=${WRKINST} ${FAKE_FLAGS} .
Read-only.
.It Ev ALL_TEST_FLAGS
Flags passed to ${MAKE} invocations during test.
Equals
.Li ${MAKE_FLAGS} ${TEST_FLAGS} .
Read-only.
.It Ev ALL_TARGET
Target used to build software.
Default is
.Sq all .
Can be set to empty, to yield a package's default target.
.It Ev APM_ARCHS
Set to the list of
.Xr apm 4
architectures.
Read-only.
Use with
.Ev ONLY_FOR_ARCHS .
.It Ev ARCH
Current machine architecture.
Read-only.
.It Ev AUTOCONF
Location of the autoconf binary if needed.
Defaults to autoconf (though autoreconf might be more appropriate).
.It Ev AUTOCONF_DIR
Where to invoke autoconf if ${CONFIGURE_STYLE} includes autoconf.
Defaults to ${WRKSRC}.
.\" AUTOCONF_DIR should probably be a list, and be renamed to AUTOCONF_DIRS ?
.It Ev AUTOCONF_VERSION
Starting with
.Ox 3.3 ,
several versions of autoconf may coexist peacefully.
The main autoconf script is a shell wrapper in the
.Pa devel/metaauto
package, and similarly for automake.
Setting
.Ev AUTOCONF_VERSION
along with
.Ev CONFIGURE_STYLE
set to autoconf is the correct way to specify which one to use.
.Ev AUTOCONF_VERSION
defaults to 2.13.
If autoconf must be run manually,
.Ev MODGNU_AUTOCONF_DEPENDS
can be used to specify what packages to depend upon.
.It Ev AUTOHEADER
Location of the autoheader binary.
Defaults to autoheader.
.It Ev AUTOMAKE_VERSION
Several versions of automake may coexist peacefully.
.Ev AUTOMAKE_VERSION
must be set before trying to run automake.
Defaults to 1.4.
Note that even if
.Ev CONFIGURE_STYLE
includes automake,
automake should still be run manually during the right
.Ar configure
stage.
.It Ev AUTOUPDATE
Location of the autoupdate binary.
Defaults to autoupdate.
.It Ev BASE_PKGPATH
Full
.Xr pkgpath 7
to the current port, taking flavors into account.
See also
.Ev BUILD_PKGPATH ,
which also includes pseudo-flavors.
Read-only.
.It Ev BASELOCALSTATEDIR
User settings.
Base location for system-wide state directory.
Defaults to
.Pa ${VARBASE} .
See
.Ev LOCALSTATEDIR .
.It Ev BASESYSCONFDIR
User settings.
Base location for system-wide configuration files.
Defaults to
.Pa /etc .
See
.Ev SYSCONFDIR .
.It Ev BATCH
User-settings.
Set to
.Sq Yes
to avoid ports that require user-interaction.
Use in conjunction with
.Ev INTERACTIVE
to simplify bulk-package builds.
.Pq See IGNORE .
.It Ev BE_ARCHS
Set to the list of big-endian architectures.
Read-only.
Use with
.Ev NOT_FOR_ARCHS
and
.Ev ONLY_FOR_ARCHS .
.It Ev BUILD_PACKAGES
The actual list of packages that will be built, once architecture problems
and pseudo-flavors have been taken into account.
See
.Qq Flavors and multi-packages .
.It Ev BROKEN
Define only for broken ports, set to reason the port is broken.
See also
.Ev NO_IGNORE ,
.Ev TRY_BROKEN .
.It Ev BROKEN-<arch>
Define only for ports broken on a given architecture.
Distinct from
.Ev ONLY_FOR_ARCHS
and
.Ev NOT_FOR_ARCHS ,
which are used to mark ports for which support for some architectures
does not exist at all, or is completely obsolete.
.It Ev BSD_INSTALL_{PROGRAM,SCRIPT,DATA,MAN}[_DIR]
Macros passed to make and configure invocations.
Set based on corresponding INSTALL_* variables.
.It Ev BUILD_DEPENDS
List of other ports the current port needs to build correctly.
Each item has the form
.Sq [pkgspec:]pkgpath[:target] .
.Sq target
defaults to
.Sq install .
The package installed must conform to the
.Sq pkgspec ,
which is by default obtained from the dependent
.Sq pkgpath
.Po
see
.Ev PKGSPEC
.Pc .
If no installation is involved, the infrastructure will still check
that the directory would provide a package conforming to the
.Sq pkgspec .
.Sq pkgpath
is set relative to ${PORTSDIR},
see
.Xr pkgpath 7
for details.
Build dependencies are checked before the
.Ar extract
stage during
.Ar prepare .
.Pp
Build dependencies with a
.Ar patch ,
.Ar configure
or
.Ar build
target will be processed in a subdirectory of the working directory,
specifically, in ${WRKDIR}/some/directory,
with
.Pa some/directory
the directory part of the
.Sq pkgpath .
.It Ev BUILD_ONCE
User settings.
Defaults to
.Sq \&No .
Set to
.Sq Yes
during bulk builds.
.Pp
When
.Ev BUILD_ONCE
is set to
.Sq Yes ,
all
.Ev PSEUDO_FLAVORS
matching
.Sq no_*
will be disabled, unless the special pseudo-flavor
.Sq bootstrap
is also set.
.Pp
This is a bulk build optimisation, automatically set by
.Xr dpb 1 :
to avoid rebuilding the same package several times, a full bulk build will
strip most ports of pseudo-packages variations that remove subpackages.
.Pp
For instance, an individual package may depend on
.Pa databases/db/v4,no_java,no_tcl ,
to avoid bringing a jdk in during a quick build.
Nevertheless, during a full bulk build,
.Pa databases/db/v4
will only be built once, as the pseudo-flavor will be automatically removed.
.Pp
However, the extra
.Sq bootstrap
rule is needed to take build cycles into account.
For instance, the
.Pa devel/dconf,-editor
subpackage depends on most of GNOME, which in turn requires
.Pa devel/dconf,-main
to build.
So
.Pa devel/dconf
has
.Li PSEUDO_FLAVORS = no_editor bootstrap
and the GNOME build first builds
.Pa devel/dconf,no_editor,bootstrap,-main
which is later used to rebuild
.Pa devel/dconf .
.It Ev BUILD_PKGPATH
Full
.Xr pkgpath 7
to the current port, taking flavors and pseudo-flavors
into account.
See also
.Ev BASE_PKGPATH ,
which doesn't include pseudo-flavors.
Mostly useful to write dependencies for subpackages like this:
.Li "LIB_DEPENDS-foo=${BUILD_PKGPATH}"
and avoid starting to build a package with some other flavor combination.
See
.Xr pkgpath 7
on the subject of
.Sq pkgpath normalisation .
Read-only.
.It Ev BULK
User settings.
If set to
.Sq Yes ,
all successful package builds and installations will clean
their working directories, after invoking
any targets mentioned in BULK_TARGETS,
and commands mentioned in BULK_DO.
Can be set on a per-${PKGPATH} basis.
For instance, setting BULK_misc/screen=No
will override any BULK=Yes passed on the command line.
If set to
.Sq Auto ,
it will apply to dependencies, but not to the current port itself.
See
.Ev BULK_COOKIES_DIR .
Defaults to
.Sq Auto .
.It Ev BULK_COOKIES_DIR
User settings.
Used to store cookies for successful bulk-package builds, defaults to
.Pa ${PORTSDIR}/bulk/${MACHINE_ARCH} .
.It Ev BULK_DO
Commands to run after each bulk package build before cleaning up the
working directory.
Empty defaults.
Can be set on a per-${PKGPATH} basis, e.g.,
BULK_DO_${PKGPATH}=...
.It Ev BULK_FLAGS
Flags to pass to build each target in
.Ev BULK_TARGETS .
.It Ev BULK_TARGETS
Targets to run after each bulk package build before cleaning up the
working directory.

BULK_TARGETS_${PKGPATH}=...
.It Ev BZIP2
Name of the bzip2 binary.
.It Ev CATEGORIES
List of descriptive categories into which this port falls.
Mandatory.
One entry must match the current pkgpath:
.Pa devel/gmake
must belong to the
.Sq devel
category.
See
.Ar link-categories ,
.Ar unlink-categories .
.It Ev CDIAGFLAGS
Flags appended to
.Ev CFLAGS
if
.Ev WARNINGS
is set.
.It Ev CCACHE_DIR
Sets the cache directory used when
.Ev USE_CCACHE
is set to yes.
Defaults to ${WRKOBJDIR}/.ccache.
.It Ev CCACHE_ENV
Sets additional environment variables when
.Ev USE_CCACHE
is set to yes.
For instance, to enable verbose logging, set
CCACHE_ENV="CCACHE_LOGFILE=/tmp/ccache.log"
.It Ev CDROM_SITE
Path to a local source that holds distribution files (usually a CD-ROM
or other similar media), used to retrieve distribution files before going
to the network.
Defaults to empty, set to
.Pa /cdrom/distfiles/${DIST_SUBDIR}
to check that path.
Distribution files are still copied or linked (see
.Ev FETCH_SYMLINK_DISFILES )
into
.Ev DISTDIR
if they are found under CDROM_SITE.
.It Ev CFLAGS
Default flags passed to the compiler for building.
Many ports ignore it.
See also
.Ev COPTS ,
.Ev CDIAGFLAGS .
.It Ev CHECK_LIB_DEPENDS
User settings.
If set to
.Sq Yes ,
every package build will verify that shared libraries are correctly
registered.
This is essentially the same as running
.Nm make Ar lib-depends-check
after each package build.
Defaults to
.Sq \&No ,
as this can be a big performance hit.
.It Ev CHECKSUMFILES
List of all files that need to be retrieved by
.Ar fetch ,
with
.Ev DIST_SUBDIR
prepended and with the master site selection extension removed.
Read-only.

User settings.
Choose whether or not to checksum packages while building.
Deposits result in
.Pa ${PACKAGE_REPOSITORY}/${MACHINE_ARCH}/cksums/${FULLPKGNAME}.sha256 .
Can be set to
.Sq Yes
to compute a checksum for all packages,
.Sq cdrom
to compute it only for
.Ev PERMIT_PACKAGE_CDROM
packages
or to
.Sq ftp
to compute it only for
.Ev PERMIT_PACKAGE_FTP
packages.
Defaults to
.Sq no ,
which does not compute a checksum at all.
.It Ev CLEANDEPENDS
If set to
.Sq Yes ,
.Sq make clean
will also clean dependencies.
Can be overridden on a per-${PKGPATH} basis,
by setting CLEANDEPENDS_${PKGPATH}.
.It Ev COMMENT
Short, one line description of the port, used for the package, and in the
INDEX.
.It Ev COMMENT-foo
Same as COMMENT but used for sub package -foo in a multi-package setup.
.It Ev COMMENT-vanilla
Same as COMMENT but used for a flavored package, if the non-flavored comment
is inappropriate.
.It Ev COMMENT-foo-vanilla
Same as COMMENT but used for a sub-, flavored package.
.It Ev COMES_WITH
The first release where the port was made part of the standard
distribution.
If the current
.Ox
version is >= this version then a notice
will be displayed instead of the port being built.
.It Ev CONFIG_SITE_LIST
Used when
.Li CONFIGURE_STYLE=gnu ,
or with
.Li MODULES += gnu .
List of
.Pa config.site
fragments that will speed up gnu-configure, and prevent it from
preferring various gnu programs, unless
.Ev BUILD_DEPENDS
explicitly ask for them.

.It Ev CONFIGURE_ARGS
Arguments to pass to configure script.
Defaults are empty, except for
GNU-style configure, where prefix and sysconfdir are set.
.It Ev CONFIGURE_ENV
Basic environment passed to configure script (path and libtool setup).
GNU-style configure adds a lot more variables.
.It Ev CONFIGURE_SCRIPT
Set to name of script invoked by
.Ar configure
target, if appropriate.
Should be either an absolute path, or relative to ${WRKSRC}.
.It Ev CONFIGURE_SHARED
Set by default to --enable-shared or --disable-shared, depending on whether
the architecture supports shared libraries.
Should be appended to CONFIGURE_ARGS, for ports that build dynamic libraries
and whose configure script supports these options.
.It Ev CONFIGURE_STYLE
Set to style of configuration that needs to happen.
.Pp
If
.Sq perl ,
assume
.Xr perl 1
.Xr ExtUtils::MakeMaker 3p
style.
Add
.Sq modbuild ,
to enable
.Xr perl 1
.Xr Module::Build 3p
or
.Sq modinst
for
.Xr Module::Install 3p
style.
.Pp
If
.Sq gnu ,
assume
GNU configure style.
Add
.Sq dest
if port does not handle DESTDIR correctly, and needs to be configured to
add DESTDIR to prefixes
.Po
see also
.Ev DESTDIRNAME
.Pc .
Add
.Sq old
if port is an older autoconf port that does not recognize --sysconfdir.
Add
.Sq autoconf
if autoconf needs to be rerun first,
but set
.Sq no-autoheader
to prevent autoheader from running.
Add
.Sq automake
if automake may need to be rerun.
Otherwise, automake will be explicitly disabled.
Note that automake is never run automatically.
In order to use it,
.Ev CONFIGURE_STYLE
should include
.Sq automake
and there should be a
.Ar {pre,do}-configure
target running automake.
.Pp
If
.Sq imake ,
assume port configures using X11 ports Imakefile framework.
Add
.Sq noman
if port has no man pages the Imakefile should try installing.
.Pp
If
.Sq simple ,
there is a configure script, but it does not fit the normal GNU configure
conventions.
.Pp
Extensions may be defined by specific MODULES.
See
.Xr port-modules 5
for details.
.It Ev COPTS
User settings.
Supplementary options appended to ${CFLAGS} for building.
Since most ports ignore the COPTS convention, they are actually told to use
${CFLAGS} ${COPTS} as CFLAGS.
.It Ev CXXDIAGFLAGS
Flags appended to
.Ev CXXFLAGS
if
.Ev WARNINGS
is set.
.It Ev CXXFLAGS
Default flags passed to the C++ compiler for building.
Many ports ignore it.

Supplementary options appended to ${CXXFLAGS} for building.
.It Ev DESTDIR
See
.Ev DESTDIRNAME .
.It Ev DESTDIRNAME
Name of variable to set to ${WRKINST} while faking.

directories and needs to be configured with
.Sq gnu dest ,
so that those few directories do not get in the way.
.It Ev DISTDIR
User settings.
Directory where all ports distribution files and patchfiles are stashed.
Defaults to
.Pa ${PORTSDIR}/distfiles .
Override if distribution files are stored elsewhere.
Always use
.Ev FULLDISTDIR
to refer to ports' distribution files location, as it takes an eventual
.Ev DIST_SUBDIR
into account.
.It Ev DISTFILES
The main port's distribution files (the actual software source, except
for binary-only ports).
Will be retrieved from the MASTER_SITES (see
.Ar fetch ) ,
checksummed and extracted (see
.Ar checksum ,
.Ar extract ) .
.Ev DISTFILES
normally holds a list of files, possibly with
.Sq :0
to
.Sq :9
appended to select a different
.Ev MASTER_SITES .
.Pp
Each entry may optionally be of the form
.Sq Ar filename Ns { Ns Ar url Ns } Ns Ar sufx
to deal with sites that only offer archives as weird urls, doing the transfer
of
.Ar url Ns Ar sufx
into result file
.Ar filename Ns Ar sufx .
For instance, if
.Bd -literal
DISTFILES = minetest-{minetest/archive/}${V}${EXTRACT_SUFX}
.Ed
.Pp
then
.Ar fetch
will retrieve from url
.Sq minetest/archive/${V}${EXTRACT_SUFX}
into
.Sq minetest-${V}${EXTRACT_SUFX} .
.Pp
If ${DISTFILES} varies depending on FLAVORS or architecture,
use
.Ev SUPDISTFILES
to ensure distfiles mirroring and
.Ar makesum
proper operation.

.It Ev ERRORS
List of errors found while parsing the port's Makefile.
Display the errors before making any target, and if any error starts with
.Qq Fatal: ,
do not make anything.
For instance:

ERRORS+="Fatal: Missing comment"
\&.endif
.Ed
Porter can add to
.Ev ERRORS ,
for instance to flag erroneous combinations of
.Ev FLAVORS
(but see
.Ev ONLY_FOR_ARCHS
.Ev NOT_FOR_ARCHS
and
.Ev BROKEN
for other common issues).
.It Ev EXTRACT_CASES
In the normal extraction stage (when
.Ev EXTRACT_ONLY
is not empty), this is the contents of a case statement, used to extract files.
Fragments are automatically appended to extract tar, xz and zip
archives, so that the default case is more or less equivalent to the
following shell fragment:
.Bd -literal
set -e
cd ${WRKDIR}
for archive in ${EXTRACT_ONLY}
do
    case $$archive in
	*.tar.xz)

.Xr ftp 1 .
Can be used to go through excessively paranoid firewalls.
Note that
.Ev FETCH_CMD
should support
.Fl C
and
.Fl o Ar dest .
.It Ev FETCH_MANUALLY
Some ports' distfiles cannot be fetched automatically for licensing reasons.
In this case, set
.Ev FETCH_MANUALLY
to a list of strings that will be displayed, one per line, e.g.,

.Sq hard ,
the
.Ar update
target will also update installed packages even when the signature
did not change.
.It Ev FULLDISTDIR
Complete path to directory where ${DISTFILES} and ${PATCHFILES} will be
located, to be used in hand-crafted extraction targets.

is always appended.
These specifications are rooted at
.Pa ${WRKINST} ,
and are subject to
.Ev SUBST_VARS
substitution, to ease
.Pa ${PREFIX}
independence.
This feature is primarily intended for large, interconnected ports,
such as the kde suite, where a base package sets up a large, extra
directory hierarchy that would make the manual checking of packing lists
tedious.
.It Ev MODGNU_CONFIG_GUESS_DIRS
If a port uses config.guess outside WRKSRC, the directories
containing the other copies must be set here.
.It Ev MODPERL_ADJ_FILES
If any files have a Perl shebang line, which needs to be replaced

.Dq #!/usr/bin/perl ,
list them in
.Ev MODPERL_ADJ_FILES .
File paths here should be relative to
.Ev WRKSRC .
These files are patched automatically at the end of
.Ar pre-configure .
.It Ev MODPERL_BIN_ADJ
Shell fragment to patch the Perl interpreter path in executable scripts.
Used by
.Ev MODPERL_ADJ_FILES .
.It Ev MODPERL_BUILD_TARGET
Normal content of
.Ar do-build
when
.Ev CONFIGURE_STYLE
uses perl.
Provided as a separate variable if a port wants to override
.Ar do-build
for its own reasons.
.It Ev MODPERL_INSTALL_TARGET
Likewise for
.Ar do-install .
.It Ev MODPERL_TEST_TARGET
Likewise for
.Ar do-test .
.It Ev MODULES
External modules mechanism, documented separately.
Modules such as
.Sq imake
and
.Sq gnu
are normally included automatically with the right
.Ev CONFIGURE_STYLE .
Note that it is possible to
.Li CONFIGURE_STYLE = simple ,
.Li MODULES += gnu
to just get the effects of
.Ev CONFIG_SITE
and
.Ev MODGNU_CONFIG_GUESS_DIRS
along with the default
.Ev TEST_TARGET ,
in case the normal GNU configure script was wrapped in a separate script that
takes different arguments.
See
.Xr port-modules 5 .
.It Ev MULTI_PACKAGES
Set to a list of subpackage extensions for ports that create multiple packages.
See
.Qq Flavors and multi-packages
below.
Especially read the part about
.Ev ONLY_FOR_ARCHS
when some of the packages only exist for some architectures.
.It NO_ARCH
Location for arch-independent packages.
Defaults to
.Sq no-arch .
Normally, packages are generated under ${PACKAGE_REPOSITORY}/${MACHINE_ARCH},
except for packages where PKG_ARCH=*, which end up under
${PACKAGE_REPOSITORY}/${NO_ARCH}.
.It Ev NOT_FOR_ARCHS
List of architectures on which this port does not build.
See also
.Ev ONLY_FOR_ARCHS .
See also
.Ev SHARED_ONLY .
Do not use instead of
.Ev SHARED_ONLY
without very good reasons.
.It Ev NO_BUILD
Set to
.Sq Yes
if port does not need any build stage.
.It Ev NO_CCACHE
Set to
.Sq Yes
to prevent ccache from being used when building a certain port,
even when
.Ev USE_CCACHE
is set.
.It Ev NO_CHECKSUM
User settings.
Set to
.Sq Yes
to avoid
.Ar checksum ,
.Ar makesum ,
and
.Ar addsum
actions entirely.
Beware of the full implications of this mechanism, namely that it disables
the basic authentication mechanisms of the ports tree entirely.
.It Ev NO_DEPENDS
User settings.
Don't verify build of dependencies.
Do not use in any ports Makefile.
This is only meant as a user convenience when, e.g., you just want to browse
through a given port's source and do not wish to trigger the build of
dependencies.
.It Ev NO_IGNORE
User settings.
If set to
.Sq Yes ,
avoid ignoring a port for the usual reasons.
Use, for instance, for fetching all distribution files, or for fixing a
broken port.
See also
.Ev IGNORE
and
.Ev TRY_BROKEN .
.It Ev NO_TEST
Port does not have any regression tests.
Only set to
.Sq Yes
for ports with no regression test.
It should be left alone for ports with empty regression tests, and for
ports with failing tests.
That way, if a subsequent update of a port acquires actual regression tests,
they will be picked up automatically.
.It Ev NO_SHARED_ARCHS
Set to the list of platforms that do not support shared libraries.
Read-only.
Use with
.Ev NOT_FOR_ARCHS .
.It Ev NO_SHARED_LIBS
Set to
.Sq Yes
if platform does not support shared libraries.
To be tested after including
.Nm bsd.port.mk ,
or
.Xr bsd.port.arch.mk 5 ,
if neither PFRAG.shared nor CONFIGURE_SHARED are enough.
.It Ev NO_SYSTRACE
Port does not build with systrace-enabled build targets.
.It Ev OLD_WRKDIR_NAME
Base name for
.Ev WRKDIR
in the old scheme without
.Ev WRKOBJDIR .
Mostly used as a value for
.Ev WRKDIR_LINKNAME ,
e.g.,
.Bd -literal
WRKDIR_LINKNAME = ${OLD_WRKDIR_NAME}
.Ed
.Pp
in
.Pa /etc/mk.conf .
Read-only.
.It Ev ONLY_FOR_ARCHS
List of architectures on which this port builds.
Can hold both processor-specific information (e.g., powerpc), and more
specific model information (e.g., macppc).
This is subpackage dependent.
Read the corresponding part of
.Qq Flavors and multi-packages
if some subpackages should only be built on some architectures.
.It Ev OSREV
Revision number of
.Ox .
Read-only.
.It Ev PACKAGE_REPOSITORY
User settings.
Location for built packages.
Defaults to
.Pa ${PORTSDIR}/packages .
See
.Ar package
for details.
.It Ev PATCH
Command to use to apply all patches.
Defaults to
.Pa /usr/bin/patch .
.It Ev PATCHORIG
Suffix used by
.Ar patch
to rename original files, and
.Ar update-patches
to re-generate
.Pa ${PATCHDIR}/${PATCH_LIST}
by looking for files using this suffix.
Defaults to
.Pa .orig .
For a port that already contains
.Pa .orig
files in the ${DISTFILES},
set this to something else, such as
.Pa .pat.orig .
See also
.Ar distpatch ,
.Ev DISTORIG .
.It Ev PATCH_CASES
In the normal distpatch stage (when
.Ev PATCHFILES
is not empty), this is the contents of a case statement, used to apply
distribution patches.
Fragments are automatically appended to handle gzip'ed, bzip'ed and lzip'ed
patches, so that the default case is more or less equivalent to the following
shell fragment:
.Bd -literal
set -e
cd ${FULLDISTDIR}
for patchfile in ${_LIST_PATCHFILES}
do
    case $$patchfile in
	*.bz2)
	  bzip2 -dc $$patchfile | ${PATCH} ${PATCH_DIST_ARGS};;
	*.lz)
	  lunzip -c $$patchfile | ${PATCH} ${PATCH_DIST_ARGS};;
	*.Z|*.gz)
	  gzcat $$patchfile | ${PATCH} ${PATCH_DIST_ARGS};;
	*)
	  ${PATCH} ${PATCH_DIST_ARGS} <$$patchfile;;
    esac
done
.Ed
.It Ev PATCHDIR
Location for patches applied by patch target.
Default:
.Pa patches .
.It Ev PATCHFILES
Files to fetch from the master sites like
.Ev DISTFILES ,
but serving a different purpose, as they hold distribution patches that
will be applied at the
.Ar patch
stage.
See also
.Ev SUPDISTFILES .
.It Ev PATCH_ARGS
Full list of options used while applying port's patches.
.It Ev PATCH_CHECK_ONLY
Set to
.Sq Yes
by the
.Ar checkpatch
target.
Don't touch unless the default
.Ar checkpatch
target needs to be redefined.
Ideally, user-defined patch subtargets ought to test checkpatch.
In practice, they don't.
.It Ev PATCH_DEBUG
If set to
.Sq Yes ,
the
.Ar patch
stage will output extra debug information.
.It Ev PATCH_DIST_ARGS
Full list of options used while applying distribution patches.
.It Ev PATCH_DIST_STRIP
Patch option used to strip directory levels while applying distribution
patches.
Defaults to -p0 .
.It Ev PATCH_LIST
Wildcard pattern of patches to select under ${PATCHDIR}.
Defaults to patch-*.
Note that filenames ending in .orig, or ~ are never applied.
Note that
.Ev PATCH_LIST
can hold absolute pathnames, for instance to share patches among similar
ports:
.Bd -literal
PATCH_LIST=${PORTSDIR}/x11/kde/libs2/patches/p-* patch-*
.Ed
.It Ev PATCH_STRIP
Patch option used to strip directory levels while applying port's patches.
Defaults to -p0 .
.It Ev PERMIT_DISTFILES_FTP , PERMIT_PACKAGE_CDROM , PERMIT_PACKAGE_FTP
Set to
.Sq Yes
if package or distribution files can be allowed on FTP sites or CD-ROM without
legal issues.
Set to reason not to otherwise.
PERMIT_* lines in the Makefile should be preceded with a comment explaining
details about licensing and patents issues the port may have.
Porters must be very thorough in their checks.
In case of doubt, ask.
.Pp
If
.Ev PERMIT_PACKAGE_CDROM
is set to
.Sq Yes ,
.Ev PERMIT_PACKAGE_FTP
and
.Ev PERMIT_DISTFILES_FTP
will default to
.Sq Yes .
.Pp
If
.Ev PERMIT_PACKAGE_FTP
is set to
.Sq Yes ,
.Ev PERMIT_DISTFILES_FTP
will default to
.Sq Yes .
.It Ev PKG_ADD
User settings.
Path to
.Xr pkg_add 1
command, with possible options.
.It Ev PKG_ARCH
Comma-separated list of architectures on which this package may install.
Defaults to ${MACHINE_ARCH},${ARCH}.
Use * for arch-independent packages.
.It Ev PKG_ARGS
Special arguments to pass to
.Xr pkg_create 1 ,
in addition to the default ones.
For mips64 and pic libraries, see
.Qq The generation of package information .
.It Ev PKG_CREATE
User settings.
Path to
.Xr pkg_create 1
command, with possible options.
Signing options should be set separately in
.Ev SIGNING_PARAMETERS .
.It Ev PKG_CREATE_NO_CHECKS
Porters switch.
Set to
.Sq Yes
to avoid checking the ports tree when solving
.Ev WANTLIB
.Po
see
.Ar wantlib-args
.Pc .
May result in bogus packages that mix
.Cm @depends
lines obtained from
the ports tree with
.Cm @wantlib
lines that come from the installed system.
Set to
.Sq Warn
to have the differences printed as a warning instead of an error
.Po
the default
.Pc .
.It Ev PKG_DBDIR
User settings.
Path to package installation records.
Defaults to
.Pa /var/db/pkg .
.It Ev PKG_DELETE
User settings.
Path to
.Xr pkg_delete 1
command, with possible options.
.It Ev PKG_INFO
User settings.
Path to
.Xr pkg_info 1
command, with possible options.
.It Ev PKG_TMPDIR
See
.Xr pkg_add 1 .
Normally points to
.Pa /var/tmp ,
as per default.
.It Ev PORTHOME
Setting of env variable
.Ev HOME
for most shell invocations.
Default will trip ports that try to write into $HOME while building.
.It Ev PORTPATH
Path used by most shell invocations.
Don't override unless really needed.
.It Ev PORTSDIR
Root of the ports tree (default:
.Pa /usr/ports ) .
.It Ev PORTSDIR_PATH
Path used by dependencies and
.Pa bsd.port.subdir.mk
to look up package specifications.
Defaults to
.Pa ${PORTSDIR}:${PORTSDIR}/mystuff .
.It Ev PKGDIR
Location for packaging information (packing list, port description, messages).
Default: pkg.
.It Ev PKGFILE
Full path to the created package for the given subpackage.
Read-only.
.It Ev PKGFILES
Full path to all created packages.
Read-only.
.It Ev PKGNAME
Name of the created package.
Default is ${DISTNAME}.
This does not take flavors into account.
See
.Ev FULLPKGNAME
for that.
Specific revisions and epoch changes should be
handled by
.Ev REVISION
and
.Ev EPOCH
instead.
.It Ev PKGNAMES
Read-only.
List of all package names generated by the port, with
.Ev FLAVORS
and
.Ev MULTI_PACKAGES
taken into account.
Mostly used as
.Sq make show=PKGNAMES
to verify that bumped package names are correct.
.It Ev PKGNAME-foo
Package name for sub-package foo, if the default value
of ${PKGNAME}${SUBPACKAGE} is not appropriate.
.It Ev PKGPATH
Path to the current port's directory, relative to ${PORTSDIR}.
Read-only.
.It Ev PKGSPEC
Default package spec for using this port as a dependency.
Defaults to
.Sq stem-* ,
derived from the
.Ev FULLPKGNAME .
Do not override without very good reasons,
namely software that coexist as different incompatible versions with the
same stem, e.g., already a mess.
.It Ev PLIST_DB
User settings.
Directory used to save generated packing-lists, as persistent information.
Packing-lists are processed by a script,
.Xr register-plist 1 ,
which complains when packing-lists change without a
.Ev REVISION
bump.
It also knows enough about package version numbers when something in the
package or its dependencies goes backward, thus catching
.Ev EPOCH
issues.
This directory is never cleaned during normal operation.
.Sq make clean=plist
should only ever be used during debugging by port maintainers.
Defaults to
.Pa ${PORTSDIR}/plist/${MACHINE_ARCH} .
If set to empty, will not register anything: very much unsafe.
.It Ev PORTS_BUILD_XENOCARA_TOO
EXPERIMENTAL.
Set to
.Sq Yes
to build xenocara through ports.
This is highly experimental and not recommended.
.It Ev PREFERRED_CIPHERS
List of cryptographic ciphers to use, in order of preference.
Default is
.Sq sha256 .
The first cipher that matches in ${CHECKSUM_FILE} is verified.
.It Ev PREFIX
Base directory for the current port installation.
Usually ${LOCALBASE}, though some ports may elect a location under
.Pa ${VARBASE} ,
and some multi-package ports may install under several locations.
Additionally, firmware files generally install under
.Pa ${BASESYSCONFDIR} .
.It Ev PREPARE_CHECK_ONLY
Build settings.
Prevent the
.Ar prepare
stage from installing anything, let it just check dependencies, and
handle [:target] dependencies.
Mostly used by
.Xr dpb 1 ,
which already installs everything before running
.Ar prepare .
.It Ev PROGRESS_METER
User-settings.
Defaults to
.Sq Yes .
Forces commands like
.Xr ftp 1
and
.Xr pkg_create 1
to use their progress-meter even in the absence of a terminal.
.It Ev PROPERTIES
List of properties specific to a given machine architecture.
Most often obtained through
.Xr bsd.port.arch.mk 5 .
These can be checked like this
.Bd -literal -offset indent
\&.include <bsd.port.arch.mk>
\&.if ${PROPERTIES:Mapm}
# then add build options specific to apm arches
\&...
\&.if !${PROPERTIES:Mlp64}
# build options specific to lp32 arches
\&...
.Ed
For
.Ev MULTI_PACKAGES
setup, use of
.Ev ONLY_FOR_ARCHS-sub
and
.Ev BUILD_PACKAGES
is generally preferred (and simpler).
Possible properties include
.Bl -tag -width no_shared
.It apm
architecture possesses suspend (apm) support.
.It be
architecture is big-endian.
.It gccN
gccN architecture.
.It elf
.Xr elf 5
architecture.
.It le
architecture is little-endian.
.It lp64
lp64 architecture.
.It no_shared
architecture has no shared library support.
.It llvm
there is
.Pa lang/llvm
support on this architecture.
.It mono
there is
.Pa lang/mono
support on this architecture.
.El
.It Ev PSEUDO_FLAVOR
List of flavors in
.Ev FLAVOR
that are actually pseudo-flavors.
Only for introspection purposes.
Read-only.
.It Ev PSEUDO_FLAVORS
Extra list of flavors that do not register in package names, but are still
used to control build logic, and work directory names.
Its only use should be for disabling part of a multi-packages build,
for instance:
.Bd -literal
FLAVOR=no_gnome make package
.Ed
.Pp
Pseudo-flavors should be named as
.Sq no_something
to disable the build of subpackage
.Sq -something
.Po
and possibly some others, by restricting
.Ev BUILD_PACKAGES
.Pc .
Pseudo-flavors should always be handled through
.Xr bsd.port.arch.mk 5 .
A pseudo-flavor can remove several subpackages through the following
construct.
.Bd -literal -offset indent
# pseudo-flavor no_gui will also remove gtk and gtk3
MULTI_PACKAGES = -main -gtk -gtk3 -gui
# ...
\&.include <bsd.port.arch.mk>

# remove extra build components
\&.if !${BUILD_PACKAGES:M-gui}
BUILD_PACKAGES := ${BUILD_PACKAGES:N-gtk:N-gtk3}
\&.endif

# normal configure setup, e.g.,
\&.if ${BUILD_PACKAGES:M-gtk}
# ...
.Ed
.Pp
Caveat: creation of a separate working directory is mandatory for a
pseudo-flavor.
If, at a later time, a full build with all subpackages is required,
all the work will need to be done again.
.Pp
See also
.Ev BUILD_ONCE .
.It Ev RCDIR
Location for daemon startup scripts.
Defaults to
.Pa /etc/rc.d .
Do not change.
.It Ev RECURSIVE_FETCH_LIST
See
.Xr mirroring-ports 7 .
.It Ev REFETCH
User settings.
If set to true,
.Ar checksum
will analyze ${CHECKSUM_FILE}, and try retrieving files with the correct
checksum off
.Pa ftp.openbsd.org ,
in the directory
.Pa /pub/OpenBSD/distfiles/$cipher/$value/$file .
.It Ev TEST_DEPENDS
See
.Ev BUILD_DEPENDS
for specification.
Test dependencies are only checked if the test stage is invoked.
.It Ev TEST_FLAGS
Extra flags passed to ${MAKE_PROGRAM} to run the regression tests.
Empty by default.
.It Ev TEST_IS_INTERACTIVE
Set to
.Sq Yes
if port needs human interaction to run its tests, or set to
.Sq X11
if the tests need an active X11 display to work.
.It Ev TEST_LOG
Command used to log the results of regression tests to TEST_LOGFILE.
.It Ev TEST_LOGFILE
Log file containing the results of regression tests.
.It Ev TEST_TARGET
Target to run regression tests.
Defaults to
.Sq regress ,
except for
.Sq perl
and
.Sq gnu
.Ev CONFIGURE_STYLE ,
which default to
.Sq test
and
.Sq check ,
respectively.
.It Ev REORDER_DEPENDENCIES
Points to a list of files that specify inter-dependencies for
.Xr make 1 .
If defined, each line of the file is either a comment (starting with #)
or a pair of two files: most_recent older.
At the end of
.Ar post-patch ,
.Xr touch 1
will be used to ensure those files are put in the proper order.
The files are assumed to be under
.Pa ${WRKSRC} .
The notation /file can be used to ask for a recursive search, e.g.,
to make sure that all Makefile.in are up-to-date.
See
.Pa ${PORTSDIR}/infrastructure/mk/automake.dep
for an example.
.It Ev REPORT_PROBLEM
See
.Xr ports 7 .
.It Ev REPORT_PROBLEM_LOGFILE
See
.Xr ports 7 .
.It Ev REVISION
Revision number of the current package.
Defaults to empty (very first package), then
numbering starts at 0.
Gets automatically incorporated into
.Ev FULLPKGNAME
as
.Sq p${REVISION}
to form a full package-name conforming to
.Xr packages-specs 7 .
.It Ev RUN_DEPENDS
Specification of ports this port needs installed to be functional.
Same format as
.Ev LIB_DEPENDS .
The corresponding packages will be built right before the
.Ar install
stage, and
.Xr pkg_add 1
will take care of installing them.
.It Ev SEPARATE_BUILD
Many GNU configure ports can be built in a directory distinct from the
place they were unpacked.
For some specific ports, this is even mandatory.
Set to
.Sq yes
or
.Sq simple
if this is the case.
The ports infrastructure will generate a separate ${WRKBUILD} directory
in which the port will be configured and built.
Wipe ${WRKBUILD} to start anew, but skipping the extract/patch stage.
.It Ev SETENV
Normally set to
.Li /usr/bin/env -i .
Prepended to every command invocation that requires a clean environment.
Do not override.
.It Ev SHARED_LIBS
List of shared libraries that the port may build, as a list of the form
.Sq libname
.Sq libversion .
Used to set variables of the form
.Ev LIBlibname_VERSION
that are then used for substitution by
.Xr pkg_create 1 .
The porter is responsible for making sure the port uses those version numbers
when shared libraries are built.
.Pp
The intent is that the
.Ox
ports system must have control over shared library versions because of global
changes that may require bumping the major version of every shared library in
the system, or simply because the third party programmers do not understand
the rules for shared library versions, thus breaking the update mechanism.
For that reason it is advised to set libversion to 0.0 when first importing a
port.
.Pp
Porters of software using libtool should make sure
.Ev MAKE_FLAGS
get propagated to the libtool invocations.
This should be enough in most cases.
.It Ev SHARED_ONLY
Set to
.Sq Yes
if port can only be built on architectures with shared libraries.
.It Ev SIGNING_PARAMETERS
User settings.
Set to
.Xr pkg_create 1
options for signing packages directly during their creation.
.It Ev SKIPDIR
See
.Xr ports 7 .
.It Ev STATIC_PLIST
Normally set to
.Sq yes .
Can be set to no for ports that do not have a static plist.
Do not change without a very good reason.
Note that the only good reason to not have a static plist is for ports such
as
.Pa databases/ports-readmes
which actually build a bunch of files depending on the current ports tree.
This breaks all introspection mechanisms within the ports tree, including
.Pa databases/pkglocatedb
which will not include that port.
.It Ev STARTAFTER
See
.Xr ports 7 .
.It Ev STARTDIR
See
.Xr ports 7 .
.It Ev SUBPACKAGE
Set to the subpackage suffix when building a package in a multi-package port.
Read-only.
Used to test for dependencies or to adjust the package name.
.It Ev SUBST_CMD
A command that can be used to perform
.Ev SUBST_VARS
substitution on arbitrary files.
In normal mode,
.Pp
.Dl ${SUBST_CMD} file1 file2 ...
.Pp
will substitute files in place, creating backup copies of them.
In copy mode,
.Pp
.Dl ${SUBST_CMD} -c src1 dest1 src2 dest2
.Pp
will copy files over while performing the substitution, as suitable for
copying template files over from
.Pa ${FILESDIR}
to
.Pa ${PREFIX} ,
for instance.
This uses
.Xr pkg_subst 1
with suitable parameters.
Read-only.
.Pp
${SUBST_CMD}
can be used like
.Xr install 1 :
.Dl ${SUBST_CMD} Oo Fl g Ar group Oc Oo Fl o Ar owner Oc Oo Fl m Ar mode Oc file...
to set file
.Ar owner ,
.Ar group
and/or
.Ar mode .
.Pp
Note that
.Ev SUBST_CMD
is not really appropriate when variables have subpackage variations, like
.Ev PREFIX
or
.Ev FULLPKGNAME .
Use the appropriate
.Ev SUBST_CMD-sub
instead.
.It Ev SUBST_CMD-sub
.Ev SUBST_CMD
with subpackage-dependent semantics, like packing-list substitution.
It will substitute the right variable depending on the desired subpackage,
e.g.,
.Ev SUBST_CMD-foo
will substitute the value of
.Ev FULLPKGNAME-foo
for
.Li ${FULLPKGNAME} .
.It Ev SUBST_VARS
Make variables whose values get substituted to create the actual package
information.
Always holds
.Ev ARCH ,
.Ev BASE_PKGPATH ,
.Ev FLAVOR_EXT ,
.Ev FULLPKGNAME ,
.Ev HOMEPAGE ,
.Ev LOCALBASE ,
.Ev MACHINE_ARCH ,
.Ev MAINTAINER ,
.Ev PREFIX ,
.Ev RCDIR ,
.Ev SYSCONFDIR ,
.Ev TRUEPREFIX ,
and
.Ev X11BASE .
The special construct
.Sq ${FLAVORS}
can be used in the packing-list to specify the current list of dash
separated flavors the port is compiled with (useful for cross-dependencies
in
.Ev MULTI_PACKAGES ) .
Add other
variables as needed.
Some variable names are prefixed by a ^.
This is only relevant for
.Ar update-plist ,
where it means the variable will only be substituted at the beginning of
a path.
.It Ev SUDO
User settings.
If set to
.Xr sudo 8
in
.Xr mk.conf 5 ,
the ports tree will only invoke root's privileges for the parts that
really require it.
.It Ev SUPDISTFILES
Supplementary files that need to be retrieved under some specific
circumstances.
For instance, a port might need architecture-specific files.
.Ev SUPDISTFILES
should hold a list of all distribution files and patchfiles that are not
always needed, so that a mirror will be able to grab all files, or that
.Ar makesum
will work.
Having an overlap between
.Ev SUPDISTFILES
and
.Ev DISTFILES ,
.Ev PATCHFILES
is admissible, and in fact, expected, as it is much simpler to build
an error-free list of files to retrieve in that way.
See the xanim port for an example.
.It Ev SYSCONFDIR
Location for this port's configuration files, should always be derived
from
.Ev BASESYSCONFDIR ,
which defaults to
.Pa /etc .
Passed to gnu configure scripts and substituted in PLISTs.
.It Ev SYSTRACE_FILTER
Location of the systrace filter file which is the basis for a port's
actual systrace policy file.
Defaults to
.Pa ${PORTSDIR}/infrastructure/db/systrace.filter .
.It Ev SYSTRACE_FILTER_CCACHE
Location of the supplementary systrace filter file which is used when
.Ev USE_CCACHE
is enabled.
Defaults to
.Pa ${PORTSDIR}/infrastructure/db/systrace.filter.ccache .
.It Ev SYSTRACE_SUBST_VARS
List of variables used in ${SYSTRACE_FILTER} that will be substituted
by their real value when creating the systrace policy file.
Always holds
.Ev WRKOBJDIR ,
.Ev PORTSDIR ,
and
.Ev DISTDIR .
.It Ev TAR
Name of the tar binary.
.It Ev TARGETS
Read-only.
Set to the list of special targets for a port
.Po
.Ar {pre,do,post}-*
and module hooks
.Pc .
Used by introspection tools such as the sqlports package.
.It Ev TEMPLATES
Base location for the templates used in the
.Ar readmes
target.
User settings.
Defaults to
.Pa ${PORTSDIR}/infrastructure/templates .
.It Ev TRUEPREFIX
Read-only.
Mostly the same as ${PREFIX}, except it never gets ${DESTDIR} prepended
during
.Ar fake .
Refer to
.Qq THE FAKE FRAMEWORK
for details.
.It Ev TRY_BROKEN
User settings.
If set to
.Sq Yes ,
don't set
.Ev IGNORE
for
.Ev BROKEN
ports, so that we will attempt to build them.
.It Ev UNLOCK_CMD
User settings.
If set, expands to a command that will release a lock.
This lock will reside in
.Pa ${LOCKDIR} .
.It Ev UNMESSAGE
File recorded in the package and displayed during deinstallation.
Defaults to ${PKGDIR}/UNMESSAGE if this file exists.
Leave empty if no message is needed.
.It Ev UNZIP
Name of the unzip binary.
.It Ev UPDATE_COOKIES_DIR
User settings.
Used to store cookies for package updates and defaults to
.Pa ${PORTSDIR}/update/${MACHINE_ARCH} .
If set to empty, will revert to a file under
.Pa ${WRKDIR} .
.It Ev USE_CCACHE
User settings.
Set to
.Sq Yes
to use ccache when building ports.
Adds a build dependency on devel/ccache, and sets up the build
environment so that it is used.
.It Ev USE_GMAKE
Set to
.Sq Yes
if GNU make (${GMAKE}) is needed for correct behavior of this port.
.It Ev USE_GROFF
Set to
.Sq Yes
to use groff to build manpages.
This sets groff as a build dependency, and also tells
.Xr pkg_create 1
to format manpages behind the scene using groff while building packages.
.It Ev USE_LIBTOOL
Defaults to
.Sq Yes .
Set to
.Sq gnu
if the base
.Xr libtool 1
is insufficient and GNU libtool is required.
Set to
.Sq \&No
to disable the use of
.Xr libtool 1
entirely; this should not be set under normal circumstances.
Adds dependencies if necessary, and passes LIBTOOL environment variable to

.It Ev USE_MFS
Set to
.Sq Yes
to build ports under an
.Xr mfs 8
filesystem.
Mostly for use by
.Xr dpb 1
and not intended to be a user setting.
See
.Ev WRKOBJDIR_MFS
for configuration.
.It Ev USE_SYSTRACE
User settings.
Set to
.Sq Yes
to protect port building with systrace.
.It Ev USE_X11
Normally, presence of ${X11BASE} is enforced by default for building ports.
But there is an experimental way to hook the xenocara build into
.Xr dpb 1 ,
which requires knowing whether a port requires X11 to already
be there.
.Pp
The infrastructure mostly sets
.Ev USE_X11
automatically based on
.Ev WANTLIB
values, there are a few ports (about 20) that require X11 components without
any library telltale.
.It Ev VARBASE
User settings.
Base location for ports that install stuff outside of
.Pa ${LOCALBASE} .
Defaults to
.Pa /var .
.It Ev WANTLIB
Extra list of library specifications that a package will need.
May include system and X11 libraries.
See
.Xr library-specs 7
for more details.
.Pp
As a special extension,
.Ev WANTLIB
may include absolute paths, e.g.,
.Pa ${LOCALBASE}/lib/expat.=4
to distinguish between base libraries and port libraries.
Use with caution, this is very seldom needed.
.It Ev wantlib_args
Controls the behavior of
.Xr pkg_create 1
related targets, see

.It Ev WARNINGS
User settings.
If set to

add
.Ev CDIAGFLAGS
to
.Ev CFLAGS
and
.Ev CXXDIAGFLAGS
to

.It Ev WRKBUILD
Subdirectory of ${WRKDIR} where the actual build occurs.
Defaults to ${WRKSRC}, unless SEPARATE_BUILD is involved, in which case
it is set to an appropriate value.
.It Ev WRKCONF
Subdirectory of ${WRKDIR} where the actual configure set occurs.
Defaults to ${WRKBUILD}.
.It Ev WRKDIR
Location where all port activity occurs.
Apart from the actual port, may
hold all kinds of cookies that checkpoint the port's build.
Read-only.
Note that WRKDIR may be a symbolic link.
During ports building,
.Pa ${WRKDIR}/bin
is put at the front of the
.Ev PATH .
.It Ev WRKDIR_LINKNAME
Name of a symbolic link to create within the port directory which will
point to the port's ${WRKDIR}.
See
.Ev OLD_WRKDIRNAME .
.It Ev WRKDIST
Subdirectory of ${WRKDIR} in which the distribution files normally unpack.
Base for all patches.
Defaults to
.Pa ${WRKDIR}/${DISTNAME} .
Note that WRKDIST may be a symbolic link, if set to ${WRKDIR}.
.It Ev WRKSRC
Subdirectory of ${WRKDIR} where the actual source is.
Base for configuration (default: ${WRKDIST}).
Note that WRKSRC may be a symbolic link, if set to ${WRKDIR}.
.It Ev WRKINST
Subdirectory of ${WRKDIR} where port normally installs (see
.Ar fake
target).
.It Ev WRKOBJDIR
Used as a base for the actual port working directory.
Defaults to
.Pa ${PORTSDIR}/pobj .
The real working directory ${WRKDIR} is created there.
Can be set on a per-${PKGPATH} basis.
For instance, setting WRKOBJDIR_www/mozilla=/tmp/obj
will affect only the mozilla port.
If explicitly unset (WRKOBJDIR=), the working directory is
created within the port directory.
.It Ev WRKOBJDIR_MFS
Alternate location for the port working directory.
The intent is to use an
.Xr mfs 8
based filesystem for small ports with
.Xr dpb 1 .
Active when
.Ev USE_MFS
is
.Sq Yes .
Defaults to
.Pa /tmp/pobj .
.It Ev X11BASE
Where X11 has been installed.
Default:
.Pa /usr/X11R6 .
.It Ev XAUTHORITY
Points to a suitable authority file for X11 interactive regression tests.
Defaults to
.Pa ${HOME}/.xauthority .
.It Ev XMKMF
Invocation of xmkmf for a
.Li CONFIGURE_STYLE=imake
port.
Defaults to xmkmf -a -DPorts.
The -DPorts is specific to
.Ox
and is always appended.
.It Ev YACC
Name of yacc program to pass to GNU-configure, defaults to yacc.
GNU-configure would always try to use bison otherwise, which leads to
unreproducible builds.
Set to bison if needed.
.El
.Sh DIAGNOSTICS
Note that some of these messages are actually emitted by some other external
commands, but grouped here for convenience: easier to look for in
.Xr dpb 1 Ns 's
logs.
.Bl -diag
.It "Error: change in plist between ..."
Error message comes from
.Xr register-plist 1 .
.It "Error: duplicate item in packing-list"
Error message comes from
.Xr pkg_create 1 ,
and will result from incorrect packing-lists, such as including several
fragments with the same file, or having incorrect
.Ev PKG_ARGS-sub .
.It "Error: Libraries in packing-lists...and libraries from installed packages don't match"
The ports tree and the installed packages are out-of-sync.
Mixing library information from both sources might produce packages that can't
be installed elsewhere.
Cleanest fix is to update the out-of-date source (e.g., update the ports tree,
or build and install new packages).
Developers may use
.Ev PKG_CREATE_NO_CHECKS
instead, assuming they understand the implications.
See print-package-args (wantlib-args) for details.
.It "Fatal: can't flavor a SUBDIR"
A dependency mentions top_subdir,flavor.
Flavor would then be ignored, as it is only applied to individual ports.
.It "Fatal: can't subpackage a SUBDIR"
A dependency mentions top_subdir,-sub.
Subpackage would then be ignored, as it is only applied to individual ports.
.It "Fatal: flavor should never start with a digit"
This would utterly confuse
.Xr pkg_add 1 .
See
.Xr packages-specs 7 .
.It "Fatal: inclusion of <file> from <file>"
.Pa bsd.port.mk
or
.Pa bsd.port.subdir.mk
has been included from a
.Ev MODULE
or from
.Pa Makefile.inc ,
resulting in a double inclusion.
This would lead to weird results, such as
.Ev PKG_ARGS
being defined twice.
.It "Fatal: SUBPACKAGES should always begin with -: <offending list>"
That is the only way to differentiate between
.Ev FLAVOR
and
.Ev SUBPACKAGE
in
.Xr pkgpath 7
specifications.
.It "Fatal: building ports requires correctly installed X11"
All file sets of the base OS, including xenocara, must be installed
before building ports.
.It "Fatal: /usr/local/lib/X11/app-defaults should exist and be a symlink"
/usr/local/lib/X11/app-defaults is distributed as a symlink in the
xshare*.tgz file set.
If xenocara was not fully installed before packages were added, it may
have been created as a directory instead.
.It "Fatal: the licencing info for <pkgname> is incomplete..."
Every port must have explicit defines of all
.Ev PERMIT_*
values.
.It "Fatal: Use 'env FLAVOR=flavor make' instead"
Arguments specified after
.Xr make 1
are hardcoded for all recursive sub-makes, and very difficult to override.
Thus,
.Ev FLAVOR
must be specified in the environment instead.
.It "Fatal: Use 'env SUBPACKAGE=-sub make' instead"
Arguments specified after
.Xr make 1
are hardcoded for all recursive sub-makes, and very difficult to override.
Thus,
.Ev SUBPACKAGE
must be specified in the environment instead.
.It "ldconfig: <dir>: No such file or directory"
Usually produced by
.Xr pkg_add 1
running
.Xr ldconfig 8 .
Some tools such as GNU libtool will add directories living under
.Pa ${WRKINST}
to the shared library path during the
.Ar fake
stage.
Of course,
.Xr ldconfig 8
will later complain after the directory no longer exists.
The bogus tool should be fixed to conform to
.Ox
usage.
.It LIB_DEPENDS <spec> not needed for <FULLPKGPATH>
There doesn't seem to be any WANTLIB to match the given LIB_DEPENDS.
Thus, the LIB_DEPENDS won't turn into a @depends line in the created package.
This is often because of confusion between LIB_DEPENDS and RUN_DEPENDS:
RUN_DEPENDS is needed for dlopen'd libraries.
.Pp
Might be intentional sometimes, if some compile flavors create static binaries,
for instance.
Also, will happen for multi-packages, where one sets LIB_DEPENDS to have
a given build dependency (and corresponding WANTLIB for a given SUBPACKAGE).
.Pp
See print-package-args (lib-depends-args) for details.
.It "Warning: FULLPKGNAME-sub defined but not FULLPKGPATH-sub"
.Ev FULLPKGNAME-sub
has been explicitly defined by the port, instead of relying on the default,
but no value of
.Ev FULLPKGPATH-sub
has been given.
This is often an error.
.It "Warning: symlink(s) point to non existent file."
Warning message comes from
.Xr pkg_create 1 .
The symlink resides in the fake area, under
.Pa ${WRKINST} .
This is only a warning because the symlink may point to a run-time dependency,
which obviously won't exist under
.Pa ${WRKINST}
at the time
.Li make package
is run.
.It "Warning: @option no-default-conflict with no @conflict"
Warning message comes from
.Xr pkg_create 1 .
Most packages that waive "default-conflict" will have explicit conflict markers
instead.
Otherwise, the package will only conflict with the exact same version, with
some possible
.Ev REVISION
bumps.
Any other version or
.Ev FLAVOR
won't conflict.
This is generally an error, apart from very few ports like
.Pa devel/autoconf/* .
.It "groff produced empty result for <manpage>..."
Warning message comes from
.Xr pkg_create 1 .
Manpages are automatically formatted with
.Xr groff 1
if
.Ev USE_GROFF
is set.
The above message denotes an actual problem while formatting the page,
which should be addressed.
In the meantime,
.Xr pkg_create 1
still produces a package, but leaves the manpage unformatted, in the hope
that something will be able to make sense of it.

.El
.Sh THE FAKE FRAMEWORK
The
.Ar fake
target is used to install the port in a private directory first, ready for
packaging by the
.Ar package
target, so that the actual installation will use the package.
.Pp
Essentially,
.Ar fake
invokes a real
.Ar install
process after tweaking a few variables.
.Pp
.Ar fake
first creates a skeleton tree under ${WRKINST}, using the
.Xr mtree 8
specification
.Pa ${PORTSDIR}/infrastructure/db/fake.mtree .
.Pp
A
.Ar pre-fake
target may be used to complete that skeleton tree.
For instance, a few ports may need supplementary stuff to be present (as
it would be installed if the port's dependencies were present).
.Pp
If
.Ar {pre,do,post}-install
overrides are present, they are used with some
important changes, listed in
.Ev FAKE_SETUP :
.Bd -literal -offset indent
TRUEPREFIX=${PREFIX}
PREFIX=${WRKINST}${PREFIX}
${DESTDIRNAME}=${WRKINST}
.Ed
.Pp
Essentially, old install targets work transparently, except for a need to
change PREFIX to TRUEPREFIX for symbolic links and similar path lookups.
Specific traditional post install work can be simply removed, as it will
be taken care of by the package itself (for instance, ldconfig, or
texinfo's install-info).
.Pp
If no
.Ar do-install
override is present, the port is installed using
.Bd -literal -offset 2n
env -i ${MAKE_ENV} ${FAKE_SETUP} ${MAKE_PROGRAM} ${ALL_FAKE_FLAGS} -f ${MAKE_FILE} ${FAKE_TARGET}
.Ed
.Pp
Note that this does set both PREFIX and ${DESTDIRNAME}.
If a port's Makefile both heeds ${DESTDIRNAME},
and references PREFIX explicitly,
FAKE_FLAGS may rectify the problem by setting PREFIX=${PREFIX}
(which will do the right thing, since ${PREFIX} is a
.Xr make 1
construct which will not be seen by the shell).
.Pp
${FAKE_FLAGS} is used to set variables on
.Xr make 1
command line, which will override the port Makefile contents.
Thus, a port that mentions DESTDIR= does not need any patch to work with fake.
.Pp
Files such as
.Pa ${PKGDIR}/README*
or
.Pa ${PKGDIR}/*.rc
get copied to
.Pa ${WRKINST}
at the end of
.Ar fake
(see the FILES section above for details).
.Sh FLAVORS AND MULTI_PACKAGES
Starting with
.Ox 2.7 ,
each port can generate distinct packages through two orthogonal mechanisms:
FLAVORS and MULTI_PACKAGES.
.Pp
The current MULTI_PACKAGES mechanism was introduced after
.Ox 4.0 .
.Pp
The arch-dependent part was refined after
.Ox 5.0 .
.Pp
If a port can be compiled with several options, these options
should be turned into FLAVORS.
The port maintainer will set FLAVORS to be the list of possible options in
the Makefile.
When building the port, the package builder will set
.Li "FLAVOR='option1 option2...'"
to build a specific flavor of the port.
The Makefile should test the value of FLAVOR as follows:
.Bd -literal -offset indent
FLAVOR?=
\&.if ${FLAVOR:Moption1}
# what to do if option1
\&.endif
\&.if ${FLAVOR:Moption2}
# what to do if option2
\&.endif
.Ed
.Pp
.Pa bsd.port.mk
takes care of a few details, such as generating a distinct work directory for
each flavor, or creating a FULLPKGNAME by adding a dash separated list of
flavors to the base package name.
The order in which FLAVOR is specified does not matter: this dash separated
list will be reordered to match the ordering of FLAVORS.
.Pp
It is an error to specify an option in FLAVOR that does not appear in FLAVORS,
to prevent misspellings.
.Pp
In bulk package building, flavors can be specified as a comma
separated list after the package directory, e.g., SUBDIR+=vim,no_x11
.Po
see
.Xr pkgpath 7
.Pc
.Pp
Finally, package information will use templates with the canonical package
extension if they are available: if FLAVOR='option1 option2' and both
COMMENT and COMMENT-option1-option2 are available, COMMENT-option1-option2 will
be used.
.Pp
If one build of a port can generate several distinct packages, set
MULTI_PACKAGES accordingly.
Each extension of a MULTI_PACKAGES name should start with a dash, so that
they cannot be confused with FLAVORS.
In dependency checking and bulk builds, a subpackage can be
specified after a comma, e.g., SUBDIR+=quake,-server.
MULTI_PACKAGES only affects the actual package building step (and the
describe step, since a MULTI_PACKAGES port will produce several
descriptions).
.Pp
If MULTI_PACKAGES is set, the packaging stage happens once for every
subpackage, using subpackage-specific variables.
For instance, if MULTI_PACKAGES=-main -lib -server,
.Ev PKG_ARCH-main ,
.Ev PKG_ARCH-lib
and
.Ev PKG_ARCH-server
will be used for the subpackages respectively called
.Ev FULLPKGNAME-main ,
.Ev FULLPKGNAME-lib
and
.Ev FULLPKGNAME-server .
.Pp
All package information is also derived from
templates with SUBPACKAGE appended.
In the preceding example, the packing-list template for FULLPKGNAME-lib
must be in PLIST-lib.
.Pp
The following variables are subpackage dependent:
.Ev COMMENT ,
.Ev PKG_ARCH ,
.Ev PERMIT_PACKAGE_FTP ,
.Ev PERMIT_PACKAGE_CDROM ,
.Ev PKGFILE ,
.Ev PKGNAME ,
.Ev FULLPKGNAME ,
.Ev REVISION ,
.Ev EPOCH ,
.Ev FULLPKGPATH ,
.Ev RUN_DEPENDS ,
.Ev WANTLIB ,
.Ev LIB_DEPENDS ,
.Ev IGNORE ,
.Ev ONLY_FOR_ARCHS ,
.Ev NOT_FOR_ARCHS ,
.Ev PKG_ARGS ,
.Ev PREFIX ,
.Ev CATEGORIES ,
.Ev MESSAGE ,
.Ev UNMESSAGE ,
.Ev DESCR ,
.Ev PLIST ,
.Ev STATIC_PLIST ,
.Ev PKGSPEC .
.Pp
The usual non-MULTI_PACKAGES variables are simply used as default values
for all subpackages.
So, if you set
.Li "PKG_ARCH=*"
.Li "PKG_ARCH-main=i386"
then
.Ev PKG_ARCH-lib
and
.Ev PKG_ARCH-server
will both be
.Sq * .
.Pp
.Ev WANTLIB
and
.Ev LIB_DEPENDS
are special.
At the beginning of the build, during
.Ar prepare ,
all build dependencies will be checked,
which includes both
.Ev LIB_DEPENDS ,
.Ev WANTLIB
and the subpackage-specific versions of these.
As an exception, any
.Ev LIB_DEPENDS-sub
that references the current port will be ignored as a build dependency,
in order to avoid recursion.
.Pp
.Ev FULLPKGPATH
and
.Ev FULLPKGNAME
are special as well.
You must set
.Ev PKGNAME-sub
or
.Ev FULLPKGNAME-sub
for each subpackage, but
.Ev FULLPKGPATH-sub
is set automatically to the right value.
In very rare cases, one may override
.Ev FULLPKGPATH-sub .
(for instance, if one specific subpackage is not affected by option
settings that affect other subpackages, e.g., for include files packs).
.Pp
In terms of using the port, quite a few targets will have a subpackage
specific subtarget:
invoking
.Ar package
is the same as invoking
.Ar subpackage
for all subpackages,
invoking
.Ar install-all
is the same as invoking
.Ar install
for all subpackages,
and invoking
.Ar update
is the same as invoking
subupdate
for all subpackages.
.Pp
.Ev ONLY_FOR_ARCHS
and
.Ev NOT_FOR_ARCHS
interact with
.Ev MULTI_PACKAGES
and
.Ev IGNORE .
The infrastructure will automatically filter subpackages
that are not suitable for the current architecture.
Thus,
.Ev MULTI_PACKAGES
should always list all subpackages,
even things not buildable on the current architecture,
for indexing purposes.
.Pp
Starting with
.Ox 5.1 ,
.Xr bsd.port.arch.mk 5
should be used to simplify the handling of
.Ev MULTI_PACKAGES
in arch-dependent setups:
.Pp
Make sure
.Ev MULTI_PACKAGES ,
.Ev ONLY_FOR_ARCHS* ,
and
.Ev PSEUDO_FLAVORS
are defined correctly, then
.Bd -literal -offset indent
\&.include <bsd.port.arch.mk>
.Ed
.Pp
This will compute
.Ev BUILD_PACKAGES ,
the list of actual subpackages to build with the current setup,
by taking arch constraints and pseudo-flavors into account.
Then test
.Ev BUILD_PACKAGES
to set up the right configuration, e.g., to check if
.Ev SUBPACKAGE
.Ar -mono
should be built:
.Bd -literal -offset indent
\&.if ${BUILD_PACKAGES:M-mono}
.Ed
.Pp
The
.Pa lang/gcc/4.2
or
.Pa print/poppler
ports should provide examples of proper use.
.Pp
Note that
.Xr dpb 1
will break if all subpackages are not properly listed.
.Sh THE GENERATION OF PACKAGE INFORMATION
Starting after
.Ox 4.1
all package information is processed directly by
.Xr pkg_create 1
from templates in ${PKG_DIR}.
.Pp
.Bl -bullet -compact
.It
If not overridden by the user, determine which set of templates to use,
depending on the current SUBPACKAGE and FLAVOR information.
Set PLIST${SUBPACKAGE}, DESCR${SUBPACKAGE}, COMMENT${SUBPACKAGE}, MESSAGE${SUBPACKAGE}, UNMESSAGE${SUBPACKAGE} accordingly.
.It
Generate the actual DESCR, and if needed, MESSAGE, UNMESSAGE,
from the templates in ${DESCR}, ${MESSAGE}, ${UNMESSAGE}, by
substituting the variables in ${SUBST_VARS}, and by substituting
${FLAVORS} with the canonical flavor extension for this port,
e.g., if FLAVORS=no_map gfx qt2, if FLAVOR=gfx no_map, this is
.Sq -no_map-gfx .
.It
Generate the actual PLIST from the template ${PLIST},
by inserting shared/no-shared fragments, merging other fragments,
and applying the same variable substitutions as other package information.
.El
.Pp
Note that ${COMMENT} is currently not substituted, to speed up
.Ar describe
generation.
.Pp
To avoid substitution, variables can be escaped as follows:
.Li "$\e{PREFIX}"
.Pp
Constructs such as the line
.Li "%%SHARED%%"
or
.Li "!%%SHARED%%"
in the packing-list template trigger the inclusion of the
.Pa ${PKGDIR}/PFRAG.shared${SUBPACKAGE}
or
.Pa ${PKGDIR}/PFRAG.no-shared${SUBPACKAGE} .
.Pp
Similarly, if FLAVORS lists flav1, then the line
.Li "%%flav1%%"
(resp.
.Li "!%%flav1%%" )
will trigger the inclusion of
.Pa ${PKGDIR}/PFRAG.flav1${SUBPACKAGE}
(resp.
.Pa ${PKGDIR}/PFRAG.no-flav1${SUBPACKAGE} )
in the packing-list.
Other fragments can be defined by simply adding
.Li "-Dfrag=1"
or
.Li "-Dfrag=0"
to
.Ev PKG_ARGS
.Pp
If libraries are built using
.Pa bsd.lib.mk ,
special care should be taken for mips64* architectures,
which do not ever build
.Pa *pic.a
files (all mips code is pic already).
.Nm
automatically adds
.Li "-Dno_mips64=1"
or
.Li "-Dno_mips64=0"
to
.Ev PKG_ARGS ,
and the porter only needs to provide the appropriate fragment.
.Pp
.Xr pkg_add 1
now calls
.Xr ldconfig 8
directly, provided dynamic libraries have been annotated with
.Li "@lib libthingy.so.5.0" .
Adding new directories to the dynamic loader cache has been
deprecated.
It is often better to let libraries be visible as a link
under ${LOCALBASE}.
Having a separate directory is enough to trick
.Xr ld 1
into grabbing the right version.
Libraries used only for
.Xr dlopen 3
do not need to be visible.
Some programs will prefer to use rpath to find their own libraries.
.Pp
The special
.Ar update-plist
target does a fairly good job of automatically generating PLIST and
PFRAG.shared fragments.
.Pp
If
.Ev PLIST_DB
points to a directory, all packing-lists from packages generated by
.Xr pkg_create 1
during the
.Ar package
stage are saved in that location by a script:
.Pa ${PORTSDIR}/infrastructure/bin/register-plist .
This script strips some irrelevant information and normalizes the
packing-list somehow, and compares it to existing information, looking
for relevant changes.
Since a package name must always be changed when the packing-list changes,
any attempt to replace a packing-list of a given name with a different
packing-list will be flagged as an error.
.Pp
In MULTI_PACKAGES mode, there must be separate COMMENT, DESCR, and PLIST
templates for each SUBPACKAGE (and optional distinct MESSAGE, UNMESSAGE
files in a similar way).
This contrasts with the FLAVORS
situation, where all these files will automatically default to the
non-flavor version if there is no flavor-specific file around.

.Pa ${PACKAGE_REPOSITORY}/${MACHINE_ARCH}/cdrom .
.It Ev COMMENT
Used to be the name of the comment file for a package.
It now holds the comment itself.
Some magic has been put in to allow for a seamless transition.
.It Ev DESCR_SRC
From
.Nx .
This is DESCR.
.Ox
does not give a specific name to the generated file.
It is not recommended to try to access it directly.
.It Ev EXTRACT_AFTER_ARGS
Was used to cobble together the normal extraction command, as
${EXTRACT_CMD} ${EXTRACT_BEFORE_ARGS} ${EXTRACT_AFTER_ARGS}.
Use
.Ev EXTRACT_CASES
instead.
.It Ev EXTRACT_BEFORE_ARGS
Likewise, use
.Ev EXTRACT_CASES
instead.
.It Ev EXTRACT_CMD
Likewise, use
.Ev EXTRACT_CASES
instead.
.It Ev FETCH_BEFORE_ARGS , Ev FETCH_AFTER_ARGS
Set
.Ev FETCH_CMD
to point to a script that does any required special treatment instead.
.It Ev FETCH_DEPENDS
Used to specify dependencies that were needed to fetch files.
It is much easier to mirror locally weird distribution files.
.It Ev FTP_PACKAGES
User settings.
Base location where packages suitable for FTP (see
PERMIT_PACKAGE_FTP) will be placed.
Now hardwired to
.Pa ${PACKAGE_REPOSITORY}/${MACHINE_ARCH}/ftp .
.It Ev GNU_CONFIGURE
Use
.Ev CONFIGURE_STYLE
instead.
.It Ev HAS_CONFIGURE
Use
.Ev CONFIGURE_STYLE
instead.
.It Ev IGNOREFILES
Set to the list of files that can't be checksummed.
All uses of it have led to postponing the correct action: talking
to the software author and getting him to provide versioned archives.
.It Ev MANn
List of unformatted manpages, per section.
.It Ev MANPREFIX
Location for storing unformatted manpages.
Derived directly from
.Ev PREFIX .
.It Ev MASTERDIR
From
.Fx .
Used to organize a collection of ports that share most files.
.Ox
uses a single port with flavors or multi-packages to produce
package variations instead.
.It Ev MASTER_SITE_SUBDIR
Contents were used to replace
.Sq %SUBDIR%
in all
.Ev MASTER_SITES
variables.
Since
.Sq %SUBDIR%
almost always occur at the end of the directory,
the simpler
.Li ${VARIABLE:=subdir/}
construct is now used instead
.Po
taken from
.Nx
.Pc .
.It Ev MD5_FILE
Use
.Ev CHECKSUM_FILE
instead.
.It Ev MIRROR_DISTFILE
Use
.Ev PERMIT_DISTFILES_FTP
to determine which files can be mirrored instead.
See
.Xr mirroring-ports 7 .
.It Ev NEED_VERSION
Used to set a requirement on a specific revision of
.Nm
needed by a port.
No longer needed as
.Nm
should always be kept up-to-date.
.It Ev NO_CONFIGURE
If ${CONFIGURE_SCRIPT} does not exist, no automatic configuration will
be done anyway.
.It Ev NO_DESCRIBE
All ports should generate a description.
.It Ev NO_EXTRACT
Set EXTRACT_ONLY= instead.
.It Ev NO_INSTALL_MANPAGES
Use
.Ev CONFIGURE_STYLE
instead.
.It Ev NO_MTREE
Starting with
.Ox 2.7 ,
the operating system installation script runs the /usr/local specification
globally, instead of embedding it in each package.
So packages no longer record an
.Xr mtree 8
specification.
Use an explicit
.Sq @exec
command if needed.
.It Ev NO_PACKAGE
All ports should generate a package, preferably before install.
.It Ev NO_PATCH
The absence of a patches directory does the same.
Use PATCHDIR and PATCH_LIST if patches need to be changed dynamically.
.It Ev NO_WRKDIR
All ports should have a working directory, as this is necessary to store
cookies and keep state.
.It Ev NO_WRKSUBDIR
The same functionality is obtained by setting WRKDIST=${WRKDIR} .
.It Ev NOCLEANDEPENDS
Use CLEANDEPENDS instead.
.It Ev NOMANCOMPRESS
.Fx
ships with compressed man pages, and uses this variable to control
that behavior.
.It Ev OBJMACHINE
Starting with
.Ox 3.3 ,
setting
.Ev WRKOBJDIR
creates the whole
.Ev WRKDIR
hierarchy under ${WRKOBJDIR}, so
.Ev OBJMACHINE
is no longer useful.
.It Ev OPSYS
The operating system.
This ports tree is only used on
.Ox .
.It Ev OPSYS_VER
Use
.Ev OSREV
instead.
.It Ev PACKAGES
Base location for packages built, everything is based on
.Ev PACKAGE_REPOSITORY
now.
.It Ev PACKAGING
Used to be set during package creation, so that the port would test it
to tweak some settings at this point.
All its effects are now achieved through
.Ev MULTI_PACKAGES .
.It Ev PATCH_SITES
.Ev PATCHFILES
used to be retrieved from a separate site list.
For greater flexibility, all files are now retrieved from
.Ev MASTER_SITES ,
.Ev MASTER_SITES0 , ... ,
.Ev MASTER_SITES9 ,
using a
.Sq :0
to
.Sq :9
extension to the file name, e.g.,
.Bd -literal -offset indent
PATCHFILES=foo.diff.gz
PATCH_SITES=ftp://ftp.zoinx.org/pub/
.Ed
.Pp
becomes
.Bd -literal -offset indent
PATCHFILES=foo.diff.gz:0
MASTER_SITES0=ftp://ftp.zoinx.org/pub/
.Ed
.It Ev PERMIT_DISTFILES_CDROM
The
.Ox
project does not ship distfiles on cdrom.
Concentrate on real questions instead, make sure
.Ev PERMIT_PACKAGE_CDROM
is set correctly.
.It Ev PKG_CMD
replaced by
.Ev PKG_CREATE .
.It Ev PKGREPOSITORY
Old user settings.
See
.Ev PACKAGE_REPOSITORY .
.It Ev PKGREPOSITORYBASE
Old user settings.
See
.Ev PACKAGE_REPOSITORY .
.It Ev PLIST_SRC
From
.Nx .
This is PLIST.
.Ox
does not give a specific name to the generated file.
It is not recommended to try to access them directly.
.It Ev PKGNAME
Used to refer to the full package name, has been superseded by
.Ev FULLPKGNAME-foo ,
for
.Ev SUBPACKAGE
-foo .
.Ev PKGNAME
now holds the package name, not taking multi-packages or flavors
into account.
Most ports are not concerned by this change.
.It Ev PLIST_SUBST
From
.Nx
and
.Fx .
Use SUBST_VARS instead.
.Ox
does not allow general substitutions of the form VAR=value, but uses
only a list of variables instead.
Most package files gets transformed, instead of only the packing list.
.It Ev RESTRICTED
Port has cryptographic issues.
.Ox
focuses on
.Ev PERMIT_PACKAGE_{FTP,CDROM}
instead.
.It Ev SED_PLIST
Old pipeline for creating packing-lists at the ports level.
Necessary functionality has been integrated directly into
.Xr pkg_create 1 .
.It Ev SCRIPTDIR
Old location for scripts related to the current port.
There is no reason for the semantic distinction, use
.Ev FILESDIR
for those.
.It Ev SCRIPTS_ENV
Used to contain the environment for invoking various scripts.
.Ev CONFIGURE_ENV
and
.Ev MAKE_ENV
are enough.
.It Ev USE_AUTOCONF
Use
.Ev CONFIGURE_STYLE
instead.
.It Ev USE_BZIP2
The framework will automatically detect the presence of
.Pa .tar.bz2
files to extract.
See also
.Ev BZIP2 , EXTRACT_CASES ,
and
.Ev EXTRACT_SUFX .
.It Ev USE_IMAKE
Use
.Ev CONFIGURE_STYLE
instead.
.It Ev USE_ZIP
The framework will automatically detect the presence of
.Pa .zip
files to extract.
See also
.Ev ZIP , EXTRACT_CASES ,
and
.Ev EXTRACT_SUFX .
.It Ev VARNAME
Use make show=name instead of make show VARNAME=name.
.It Ev WRKPKG
Directory used to build package information from the templates under
.Pa ${PKGDIR} .
This information is now built on the fly by
.Xr pkg_create 1 .
.El
.Sh OBSOLETE FILES
.Bl -tag -width files/md5
.It Pa {files,patches,pkg}.${ARCH}
Offensive to introspection, makes it impossible to build a decent sqlports
on a given arch.
Hasn't been used for a long time, and there are lots of mechanisms such as
.Ev PKG_ARGS
and fragment substitution, or
.Ev PATCH_LIST
to achieve similar results.
.It Pa Makefile.${ARCH}
Likewise, offensive to introspection too.
.It Pa ${FILESDIR}/md5
Renamed to
.Pa distinfo
to match other
.Bx ,
and save directories.
.It Pa ${SCRIPTDIR}/{pre,do,post}-*
Identical functionality can be obtained through a {pre,do,post}-* target,
invoking the script manually if necessary.
.It Pa ${SCRIPTDIR}/configure
No longer invoked automatically.
Just inline the instructions in
.Ar do-configure
in the Makefile, or put the script in ${FILESDIR} and
invoke it.
.It Pa ${PKGDIR}/COMMENT
Use COMMENT variable instead.
.It Pa ${PKGDIR}/DEINSTALL*
Use @unexec annotations in the packing-list instead.
.It Pa ${PKGDIR}/INSTALL*
Use @exec annotations in the packing-list instead.
.It Pa ${PKGDIR}/PLIST.noshared
Use PFRAG.shared or PFRAG.no-shared instead.
PLIST.noshared was too easy to forget when updating ports.
.It Pa ${PKGDIR}/PLIST.sed
Use PLIST directly.
Until revision 1.295,
.Nm
did not substitute variables in the packing list unless this special form
was used.
.It Pa ${PKGDIR}/REQ*
Old requirement script.
Was mostly unused anyway.
.It Pa /usr/share/mk/bsd.port.mk
Original location of
.Nm bsd.port.mk .
The current file lives under
.Pa ${PORTSDIR}/infrastructure/mk/bsd.port.mk ,
whereas
.Pa /usr/share/mk/bsd.port.mk
is just a stub.
.It Pa {scripts,files,patches}.${OPSYS}
The
.Ox
ports tree focuses on robustness, not on being portable to other operating
systems.
In any case, portability should not need to depend on operating
system dependent patches.
.It Pa /usr/local/etc
Used by
.Fx
to marshall system configuration files.
All
.Ox
system configuration files are located in
.Pa /etc ,
or in a subdirectory of
.Pa /etc .

.Sh HISTORY
The ports mechanism originally came from
.Fx .
A lot of additions were taken from
.Nx
over the seminal years.
.Pp
Since 1998, the framework has been systematically cleaned-up and reorganized
to remove bugs.
New features have been carefully introduced, trying hard to avoid
inconsistencies.
.Pp
FLAVORS, MULTI_PACKAGES and FAKE are
.Ox
improvements.
Most recent additions do not come from another
.Bx .
.\" Voluntarily undocumented:
.\" AUTOCONF_ENV: probably not needed anyway, should be internal.
.Sh BUGS AND LIMITATIONS
.Ev LOCALBASE ,
.Ev X11BASE ,
.Ev SYSCONFDIR
and
.Ev PREFIX
are not heeded consistently.
Most of the ports tree will probably fall
apart if one tries to build/use stuff elsewhere.
