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. You
|
1994-08-31 02:42:54 +08:00
|
|
|
must install GNU m4 (version 1.1 or later, preferably 1.3 or later
|
|
|
|
|
for better performance) before configuring Autoconf, so that
|
|
|
|
|
Autoconf's configure script can find it. The configuration scripts
|
|
|
|
|
produced by Autoconf are self-contained, so their users do not need to
|
|
|
|
|
have Autoconf (or GNU m4).

Also, some optional utilities that come with Autoconf use Perl, TCL,
|
|
|
|
|
and the TCL packages Expect and DejaGNU. However, none of those
|
1994-08-10 00:21:46 +08:00
|
|
|
are required in order to use the main Autoconf program. If they are
|
|
|
|
|
not present, the affected Autoconf utilities will not be installed.

|
The file INSTALL can 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.
|
|
|
|
|
|
|
|
|
|
The file `acconfig.h' contains short descriptions of the C preprocessor
|
|
|
|
|
variables that Autoconf can define, suitable for copying into other
|
|
|
|
|
packages' configuration headers or Makefile.in files. You can use the
|
1994-07-27 01:15:52 +08:00
|
|
|
program `autoheader' to automatically create a configuration header
|
1993-01-01 07:22:37 +08:00
|
|
|
from a `configure.in', based on the information in `acconfig.h'.
