Usage: $0 [OPTION] ... [TEMPLATE-FILE]
|
|
|
|
Run \`autoconf' (and \`autoheader', \`aclocal' and \`automake', 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 predecessors. If you install a new version of
|
|
Autoconf, 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 every files are 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:
|
|
-A, --autoconf-dir=ACDIR Autoconf's macro files location (rarely needed)
|
|
-l, --localdir=DIR location of \`aclocal.m4' and \`acconfig.h'
|
|
-M, --m4dir=M4DIR this package's Autoconf extensions
|
|
|
|
Unless specified, heuristics try to compute \`M4DIR' from the \`Makefile.am',
|
|
or defaults to \`m4' if it exists.
|
|
|
|
The following options are passed to \`automake':
|
|
--cygnus assume program is part of Cygnus-style tree
|
|
--foreign set strictness to foreign
|
|
--gnits set strictness to gnits
|
|
--gnu set strictness to gnu
|
|
--include-deps include generated dependencies in Makefile.in
|
|
|
|
The environment variables AUTOCONF, AUTOHEADER, AUTOMAKE, and ACLOCAL
|
|
are honored.
|
|
|
|
