16 | Autoconf is a tool for producing shell scripts that automatically
|
---|
17 | configure software source code packages to adapt to many kinds of
|
---|
18 | UNIX-like systems. The configuration scripts produced by Autoconf are
|
---|
19 | independent of Autoconf when they are run, so their users do not need to
|
---|
20 | have Autoconf.

28 | The autoheader program can create a template file of C #define

37 | If you have a lot of Autoconf-generated configure scripts, the
|
---|
38 | autoreconf program can save you some work. It runs autoconf (and
|
---|
39 | autoheader, where appropriate) repeatedly to remake the Autoconf
|
---|
40 | configure scripts and configuration header templates in the directory
|
---|
41 | tree rooted at the current directory.

48 | <para>
|
---|
49 | The autoscan program can help you create a configure.in file for
|
---|
50 | a software package. autoscan examines source files in the directory
|
---|
51 | tree rooted at a directory given as a command line argument, or the
|
---|
52 | current directory if none is given. It searches the source files for
|
---|
53 | common portability problems and creates a file configure.scan which
|
---|
54 | is a preliminary configure.in for that package.

|
---|
60 |
|
---|
61 | <para>
|
---|
62 | The autoupdate program updates a configure.in file that calls
|
---|
63 | Autoconf macros by their old names to use the current macro names.

|
---|
70 | <para>
|
---|
71 | ifnames can help when writing a configure.in for a software
|
---|
72 | package. It prints the identifiers that the package already uses in C
|
---|
73 | preprocessor conditionals. If a package has already been set up to
|
---|
74 | have some portability, this program can help you figure out what its
|
---|
75 | configure needs to check for. It may help fill in some gaps in a
|
---|
76 | configure.in generated by autoscan.
