NAME
autoreconf2.13 - update configure scripts
SYNOPSIS
autoreconf2.13 [ --help | -h ] [ --force | -f ] [ --localdir=dir | -l
dir ] [ --macrodir=dir | -m dir ] [ --verbose ] [ --version ]
DESCRIPTION
If you have a lot of Autoconf-generated configure scripts, the
autoreconf2.13 program can save you some work. It runs autoconf2.13
(and autoheader2.13, 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.in or (if
present) aclocal.m4. Since autoheader2.13 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 autoreconf2.13 remake all of the
files by giving it the --force option.
If you give autoreconf2.13 the --macrodir=DIR or --localdir=DIR
options, it passes them down to autoconf2.13 and autoheader2.13 (with
relative paths adjusted properly).
autoreconf2.13 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.
autoreconf2.13 accepts the following options:
--help
-h Print a summary of the command line options and exit.
--force
-f Remake even configure scripts and configuration headers that are
newer than their input files (configure.in and, if present,
aclocal.m4).
--localdir=DIR
-l DIR Look for the package file aclocal.m4 in directory DIR instead of
in the current directory.
--macrodir=DIR
-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.
--verbose
Print the name of each directory where autoreconf2.13 runs
autoconf2.13 (and autoheader2.13, if appropriate).
--version
Print the version number of Autoconf and exit.
