NAME

autoreconf - Update generated configuration files

SYNOPSIS

autoreconf [OPTION]... [DIRECTORY]...

DESCRIPTION

Run 'autoconf' and, when needed, 'aclocal', 'autoheader', 'automake', 'autopoint' (formerly 'gettextize'), 'libtoolize', 'intltoolize', and 'gtkdocize' to regenerate the GNU Build System files in specified DIRECTORIES and their subdirectories (defaulting to '.').

By default, it only remakes those files that are older than their sources. If you install new versions of the GNU Build System, you can make 'autoreconf' remake all of the files by giving it the '--force' option.

Operation modes:

print this help, then exit
print version number, then exit
verbosely report processing
don't remove temporary files
consider all generated and standard files obsolete
copy missing standard auxiliary files
don't rebuild sub-packages
with -i, install symbolic links instead of copies
when applicable, re-run ./configure && make
report the warnings falling in CATEGORY (comma-separated list accepted)

Warning categories are:

cross compilation issues
GNU coding standards (default in gnu and gnits modes)
obsolete features or constructions (default)
user redefinitions of Automake rules or variables
portability issues (default in gnu and gnits modes)
portability-recursive
nested Make variables (default with -Wportability)
extra portability issues related to obscure tools
dubious syntactic constructs (default)
unsupported or incomplete features (default)

-W also understands:

turn on all the warnings
turn off all the warnings
turn off warnings in CATEGORY
treat all enabled warnings as errors

Library directories:

prepend directory DIR to search path
append directory DIR to search path

The environment variables AUTOCONF, ACLOCAL, AUTOHEADER, AUTOM4TE, AUTOMAKE, AUTOPOINT, GTKDOCIZE, INTLTOOLIZE, LIBTOOLIZE, M4, MAKE, and WARNINGS are honored.
