Slightly trimmed down version of fix by assar@sics.se
(strtol failure is usually simpler to test, and error messages should
identify the program that produces them)
|
|
- don't interfere with MACHINE/MACHINE_ARCH defines for bootstrap
- type clean-up, time_t, and printing `unknown' ints
- fix TARGET/MEMBER bug in archive rules
- memmove...
- cleaner Error handler.
- reentrant brk_string
- .MAKE env variable
- preliminary scaffolding for .NOPATH
Other improvements:
- efree
- shellneed streamlined
- display Stop in .CURDIR after an error.
- document most features and misfeatures.
- add a few OpenBSD notes to the tutorial.

- fix the variable substitution code in make [PR/2748]
1. change s/a/b/ so that it substitutes the first occurance of the
pattern on each word, not only the first word.
2. add flag '1' to the variable substitution so that the substitutions
get performed only once.
***THIS IS AN INCOMPATIBLE CHANGE!***
Unfortunately there was no way to make things consistent without
modifying the current behavior. Fortunately none of our Makefiles
depended on this.
OLD:
VAR = aa1 aa2 aa3 aa4
S/a/b/ = ba1 aa2 aa3 aa4
S/a/b/g = bb1 bb2 bb3 bb4
NEW:
VAR = aa1 aa2 aa3 aa4
S/a/b/ = ba1 ba2 ba3 ba4
S/a/b/1 = ba1 aa2 aa3 aa4
S/a/b/g = bb1 bb2 bb3 bb4
S/a/b/1g = bb1 aa2 aa3 aa4
- add regexp variable substitution via 'C/foo/bar/' [PR/2752]
- add variable quoting via the ${VAR:Q} modifier. This is useful when running
recursive invocations of make(1):
make VAR=${VAR:Q}
will always work... (This may prove useful in the kernel builds...) [PR/2981]
- BSD did not traditionally have <sys/cdefs.h>; use BSD4_4 instead and include
<sys/param.h> to grab it.
- Don't compile the regex code if MAKE_BOOTSTRAP (from gwr)
- Use explicit .c.o rule in Makefile.boot so that the bootstrap process works.
- Use only integral types in procedure arguments. [buf.c buf.h]
- Include <stdlib.h> to get getenv() prototype on SVR4
- if __STDC__ -> ifdef __STDC__ to appease SVR4
- Define const and volatile for non __STDC__
- Implement snprintf() and vsnprintf() for non BSD4_4 systems.
- Make $MACHINE_ARCH settable from the environment.
- Fix .USE directive problems: (reported by cgd)
1. ${.*} variables did not get expanded in dependencies.
2. expanded ${.*} variables in .USE dependencies can cause tree
restructuring; handle it.
3. in compat mode, expand .USE before evaluating the list of targets,
instead of doing .USE expansions on demand, because they can cause
tree restructuring.
- Add a .MADE directive to indicated that the children of a target are
up-to-date, even when they are not. This is to simulate our current
make install behavior with proper dependencies.
- Fix problems in the RE substitution error handling.
- Locate all the children of a node marked as MADE.
- Do not compile-in ${MACHINE} (as per NetBSD PR#3386)
- Disable globbing for targets/dependencies when POSIX is defined.
- Fix globbing so that patterns that don't have a matching number of [] or {}
don't get expanded. (before the [ case got expanded to nothing!) This is
disabled.
- Make sure that the children of nodes that are marked .MADE, are marked
UPTODATE and their timestamps are consistent.
- Don't disable wildcards completely; they are used by other Makefiles.

comment accordingly. Patch from Dale Rahn.

- Merge in FreeBSD and Lite2 changes.
- Fix bug where a non-archive target with a .a suffix would always
be considered to be out of date, since it does not have a TOC.
- Fix NetBSD PR #2930: declare missing variable.

Fix bug reported by Greg Hudson where leaf (source only) nodes were
referenced only by their basename and not by their full pathname. This
breaks when .PATH or MAKEOBJDIR are used. There might be Makefiles
around that try to work around this bug by prepending ${.CURDIR} to
the sources, and they should be found and fixed. Also a lot of the gunk
in suff.c that was attempting to work around the same problem could be
removed.
(christos)
- Move -D flags from Makefile to config.h and explain what they do. Add
-Wall -Wno-unused to CFLAGS. Add new define SYSVVARSUB to enable SysV
style variable substitutions and enable them.
- Add SunOS style command substitutions via SUNSHCMD
- Fix core dump with '{variable = value'
(christos)
Fix bug where make will always exit with 0, even when one or more
parallel jobs failed. (Only affects parallel make code)
(christos)
Protect __P from being multiply defined (for systems that already
define it)
(christos) Add strdup() since ultrix is missing it.
From Larry Schwimmer <rosebud@cyclone.Stanford.EDU>
(christos) Add estrdup(), a checked version of strdup and use it.
(christos) Recognize SVR4 style long filename entries in archives.
(thorpej) Tidy up some RCS ids a bit.

custom search path, like $DESTDIR/usr/share/mk
|

Support SVR4 style archives.
Fix pr/1421 (from Matthew Green) and pr/1997 (from Jeff Thieleke).
In ParseDoInclude(), make a temporary copy of the current file name
while searching for ""-type include files, since the current file name
might not be a writeable string.

then kvm_getargv will show a nice unhacked argument list

Minor:
- ${.PREFIX} should never contain a full pathname
- Fixed gcc -Wall warnings
Major:
- compatMake is now FALSE. This means that we are now running in
full pmake mode:
* rules on dependency lines can be executed in parallel and or
out of sequence:
foo: bar baz
can fire the rule for baz before the rule for bar is fired.
To enforce bar to be fired before baz, another rule needs to be
added. [bar: baz]
* adjacent shell commands in a target are now executed by a single
invocation of the shell, not one invocation of the shell per line
(compatMake can be turned off using the -B flag)
- The -j flag now works... I.e. make -j 4 will fork up to four jobs in
parallel when it can. The target name is printed before each burst
of output caused by the target execution as '--- target ---', when j > 1
- I have changed all the Makefiles so that they work with make -j N, and
I have tested the whole netbsd by:
'make -j 4 cleandir; make -j 4 depend; make -j 4; make -j 4 install'
- I have not compiled or tested this version of make with -DREMOTE.
- Turn compat mode on by default. It gets turned off when the -j without
the -B flag is specified. [Thus you can use -j 1 to turn it off].
- Fix malloc -> emalloc as Gordon noted.
Updates for POSIX/SVR4 compiling:
arch.c: Don't require ranlib stuff. Not everybody has it.
dir.c: SunOS-4 != Solaris; change #ifdef sun to #if sun && !__svr4__
job.c, compat.c: Don't use 'union wait', use int and the W*() macros.
main.c: Check for uname() == -1; some unames return > 0...
util.c, job.c: Add signal() with BSD semantics for svr4, don't use bsd
sigmask and friends.
from cgd@netbsd:
pull in make.h. (PAlloc() now uses emalloc(), which is prototyped in
make.h. If the prototype is not in scope on the Alpha, I see lots
of "cast to pointer from integer of different size" warnings.)
