$OpenBSD: INSTALL,v 1.1 1996/08/14 06:19:10 downsj Exp $ [This file is the generic GNU autoconf/configure installation description, see the README for pdksh specific configuration/installation information] This is a generic INSTALL file for utilities distributions. If this package does not come with, e.g., installable documentation or data files, please ignore the references to them below. The `configure' shell script attempts to guess correct values for various system-dependent variables used during compilation, and creates the Makefile(s) (one in each subdirectory of the source directory). In some packages it creates a C header file containing system-dependent definitions. It also creates a file `config.status' that you can run in the future to recreate the current configuration. To compile this package: 1. Configure the package for your system. Normally, you just `cd' to the directory containing the package's source code and type `./configure'. If you're using `csh' on an old version of System V, you might need to type `sh configure' instead to prevent `csh' from trying to execute `configure' itself. Running `configure' takes awhile. While it is running, it prints some messages that tell what it is doing. If you don't want to see any messages, run `configure' with its standard output redirected to `/dev/null'; for example, `./configure >/dev/null'. To compile the package in a different directory from the one containing the source code, you must use a version of `make' that supports the `VPATH' variable, such as GNU `make'. `cd' to the directory where you want the object files and executables to go and run the `configure' script. `configure' automatically checks for the source code in the directory that `configure' is in and in `..'. If for some reason `configure' is not in the source code directory that you are configuring, then it will report that it can't find the source code. In that case, run `configure' with the option `--srcdir=DIR', where DIR is the directory that contains the source code. By default, `make install' will install the package's files in `/usr/local/bin', `/usr/local/man', etc. You can specify an installation prefix other than `/usr/local' by giving `configure' the option `--prefix=PATH'. Alternately, you can do so by consistently giving a value for the `prefix' variable when you run `make', e.g., make prefix=/usr/gnu make prefix=/usr/gnu install You can specify separate installation prefixes for architecture-specific files and architecture-independent files. If you give `configure' the option `--exec-prefix=PATH' or set the `make' variable `exec_prefix' to PATH, the package will use PATH as the prefix for installing programs and libraries. Data files and documentation will still use the regular prefix. Normally, all files are installed using the same prefix. Some packages pay attention to `--with-PACKAGE' options to `configure', where PACKAGE is something like `gnu-as' or `x' (for the X Window System). They may also pay attention to `--enable-FEATURE' options, where FEATURE indicates an optional part of the package. The README should mention any `--with-' and `--enable-' options that the package recognizes. `configure' also recognizes the following options: `--help' Print a summary of the options to `configure', and exit. `--quiet' `--silent' Do not print messages saying which checks are being made. `--verbose' Print the results of the checks. `--version' Print the version of Autoconf used to generate the `configure' script, and exit. `--x-includes=DIR' X include files are in DIR. `--x-libraries=DIR' X library files are in DIR. `configure' also accepts and ignores some other options. On systems that require unusual options for compilation or linking that the package's `configure' script does not know about, you can give `configure' initial values for variables by setting them in the environment. In Bourne-compatible shells, you can do that on the command line like this: CC='gcc -traditional' LIBS=-lposix ./configure On systems that have the `env' program, you can do it like this: env CC='gcc -traditional' LIBS=-lposix ./configure Here are the `make' variables that you might want to override with environment variables when running `configure'. For these variables, any value given in the environment overrides the value that `configure' would choose: - Variable: CC C compiler program. The default is `cc'. - Variable: INSTALL Program to use to install files. The default is `install' if you have it, `cp' otherwise. For these variables, any value given in the environment is added to the value that `configure' chooses: - Variable: DEFS Configuration options, in the form `-Dfoo -Dbar...'. Do not use this variable in packages that create a configuration header file. - Variable: LIBS Libraries to link with, in the form `-lfoo -lbar...'. If you need to do unusual things to compile the package, we encourage you to figure out how `configure' could check whether to do them, and mail diffs or instructions to the address given in the README so we can include them in the next release. 2. Type `make' to compile the package. If you want, you can override the `make' variables CFLAGS and LDFLAGS like this: make CFLAGS=-O2 LDFLAGS=-s 3. If the package comes with self-tests and you want to run them, type `make check'. If you're not sure whether there are any, try it; if `make' responds with something like make: *** No way to make target `check'. Stop. then the package does not come with self-tests. 4. Type `make install' to install programs, data files, and documentation. 5. You can remove the program binaries and object files from the source directory by typing `make clean'. To also remove the Makefile(s), the header file containing system-dependent definitions (if the package uses one), and `config.status' (all the files that `configure' created), type `make distclean'. The file `configure.in' is used to create `configure' by a program called `autoconf'. You only need it if you want to regenerate `configure' using a newer version of `autoconf'.
