autoreconf - update configure scripts
autoreconf [ --help | -h ] [ --version | -V ] [ --verbose | -v ] [
--debug | -d ] [ --force | -f ] [ --install | -i ] [ --symlink | -s ] [
--localdir=dir | -l dir ] [ --autoconf-dir=dir | -A dir ] [
--m4-dir=dir | -M dir ] [ --cygnus ] [ --foreign ] [ --gnits ] [ --gnu
] [ --include-deps ]
If you have a lot of Autoconf-generated configure scripts, the autore-
conf program can save you some work. It runs autoconf (and autoheader,
where appropriate) repeatedly to remake the Autoconf configure scripts
and configuration header templates in the directory tree rooted at the
current directory. By default, it only remakes those files that are
older than their configure.ac or (if present) aclocal.m4. Since auto-
header does not change the timestamp of its output file if the file
wouldn't be changing, this is not necessarily the minimum amount of
work. If you install a new version of Autoconf, you can make autore-
conf remake all of the files by giving it the --force option.
If you give autoreconf the --autoconf-dir=dir or --localdir=dir
options, it passes them down to autoconf and autoheader (with relative
paths adjusted properly).
autoreconf does not support having, in the same directory tree, both
directories that are parts of a larger package (sharing aclocal.m4 and
acconfig.h), and directories that are independent packages (each with
their own aclocal.m4 and acconfig.h). It assumes that they are all
part of the same package, if you use --localdir, or that each directory
is a separate package, if you don't use it. This restriction may be
removed in the future.
autoreconf accepts the following options:
-h Print a summary of the command line options and exit.
-V Print the version number of Autoconf and exit.
Print the name of each directory where autoreconf runs autoconf
(and autoheader, if appropriate).
-d Don't remove the temporary files.
-f Remake even configure scripts and configuration headers that are
newer than their input files (configure.ac and, if present,
-i Copy missing auxiliary files. This option is similar to the
option --add-missing in automake.
-s Instead of copying missing auxiliary files, install symbolic
-l dir Look for the package file aclocal.m4 in directory dir instead of
in the current directory.
-m dir Look for the installed macro files in directory dir. You can
also set the AC_MACRODIR environment variable to a directory;
this option overrides the environment variable.
-M dir Specify location of additional macro files (m4 by default).
These options are recognized and passed through to automake.
