Autoconf
|
|
|
|
Autoconf is an extensible package of M4 macros that produce shell
|
|
scripts to automatically configure software source code packages.
|
|
These scripts can adapt the packages to many kinds of UNIX-like
|
|
systems without manual user intervention. Autoconf creates a
|
|
configuration script for a package from a template file that lists the
|
|
operating system features that the package can use, in the form of M4
|
|
macro calls.
|
|
|
|
Producing configuration scripts using Autoconf requires GNU M4 and
|
|
Perl. You should install GNU M4 (version 1.4.6 or later is required;
|
|
1.4.13 or later is recommended) and Perl (5.005_03 or later) before
|
|
configuring Autoconf, so that Autoconf's configure script can find
|
|
them. The configuration scripts produced by Autoconf are
|
|
self-contained, so their users do not need to have Autoconf (or GNU
|
|
M4, Perl, etc.).
|
|
|
|
You can get GNU M4 here:
|
|
|
|
ftp://ftp.gnu.org/gnu/m4/
|
|
|
|
The file INSTALL should be distributed with packages that use
|
|
Autoconf-generated configure scripts and Makefiles that conform to the
|
|
GNU coding standards. The package's README can just give an overview
|
|
of the package, where to report bugs, and a pointer to INSTALL for
|
|
instructions on compilation and installation. This removes the need
|
|
to maintain many similar sets of installation instructions.
|
|
|
|
Be sure to read BUGS and INSTALL.
|
|
|
|
Mail suggestions to autoconf@gnu.org, report bugs to
|
|
bug-autoconf@gnu.org, and submit patches to autoconf-patches@gnu.org.
|
|
All changes can be tracked at the read-only autoconf-commit@gnu.org.
|
|
Always include the Autoconf version number, which you can get by
|
|
running `autoconf --version'. Archives of bug-autoconf@gnu.org can be
|
|
found in <http://lists.gnu.org/archive/html/bug-autoconf/>, and
|
|
similarly for the other mailing lists.
|
|
