6.35. Autoconf-2.68
The Autoconf package contains programs for producing shell scripts that can automatically configure source code.
Approximate build time: 4.8 SBU
Required disk space: 12.4 MB
6.35.1. Installation of Autoconf
Prepare Autoconf for compilation:
./configure --prefix=/usr
Compile the package:
make
To test the results, issue:
make check
This takes a long time, about 4.7 SBUs. In addition, 6 tests are skipped that use Automake. For full test coverage,
Autoconf can be re-tested after Automake has been installed.
Install the package:
make install
6.35.2. Contents of Autoconf
Installed programs: autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate, and ifnames
Installed directory: /usr/share/autoconf
Short Descriptions
autoconf Produces shell scripts that automatically configure software source code packages to adapt to many
kinds of Unix-like systems. The configuration scripts it produces are independent—running them
does not require the autoconf program.
autoheader A tool for creating template files of C #define statements for configure to use
autom4te A wrapper for the M4 macro processor
autoreconf Automatically runs autoconf, autoheader, aclocal, automake, gettextize, and libtoolize in the
correct order to save time when changes are made to autoconf and automake template files
autoscan Helps to create a configure.in file for a software package; it examines the source files in a
directory tree, searching them for common portability issues, and creates a configure.scan
file that serves as as a preliminary configure.in file for the package
autoupdate Modifies a configure.in file that still calls autoconf macros by their old names to use the
current macro names
ifnames Helps when writing configure.in files for a software package; it prints the identifiers that the
package uses in C preprocessor conditionals. If a package has already been set up to have some
portability, this program can help determine what configure needs to check for. It can also fill in
gaps in a configure.in file generated by autoscan
