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 1.4.5 or later is required;
|
|
1.4.11 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 (especially if this version is not an official
|
|
release) 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.

|
Licensing
|
|
|
|
Autoconf is released under the General Public License (GPL).
|
|
Additionally, Autoconf includes a licensing exception in some of its
|
|
source files; see the respective copyright notices for how your
|
|
project is impacted by including scripts generated by Autoconf.
|
|
|
|
This version of Autoconf uses GPLv2+ plus the above-mentioned
|
|
exceptions for its installed executables, as described in COPYING.
|
|
Meanwhile, several source files within the Autoconf project are under
|
|
GPLv3+, as described in COPYINGv3; these files are used for building
|
|
and installing Autoconf, but are not present in the installed
|
|
programs. The entire Autoconf project will move to GPLv3+ when the
|
|
exception statements have been reformulated in terms of the Additional
|
|
Permissions as described in section 7 of GPLv3.
|
