unchanged, remove the source. (&up_to_date_p): Don't be verbose, be debug. * bin/autoreconf.in: No longer support --m4dir. (&autoreconf): Display the full path of the configure.ac we are studying. Trace it only once. Be sure to honor --force with gettextize. Always run aclocal. * doc/autoconf.texi: Adjust.

|
|
Run `autoconf' (and `autoheader', `aclocal', `automake', `gettextize',
|
|
and `libtoolize' where appropriate) repeatedly to remake the GNU Build
|
|
System files in the directory tree rooted at the current directory.
|
|
By default, it only remakes those files that are older than their
|
|
predecessors. If you install new versions of the GNU Build System,
|
|
running `autoreconf' remakes all of the files by giving it the
|
|
`--force' option.
|
|
|
|
Operation modes:
|
|
-h, --help print this help, then exit
|
|
-V, --version print version number, then exit
|
|
-v, --verbose verbosely report processing
|
|
-d, --debug don't remove temporary files
|
|
-f, --force consider all files obsolete
|
|
-i, --install copy missing auxiliary files
|
|
-s, --symlink instead of copying, install symbolic links
|
|
|
|
The option `--install' is similar to the option `--add-missing' in
|
|
other tools.
|
|
|
|
Library directories:
|
|
-I, --include=DIR look for FILES in DIR (cumulative)
|
|
|
|
The environment variables AUTOCONF, AUTOHEADER, AUTOMAKE, ACLOCAL,
|
|
GETTEXTIZE, LIBTOOLIZE are honored.
|
|
|
