NAME

autoreconf - Update generated configuration files

SYNOPSIS

autoreconf2.72 [OPTION]... [DIRECTORY]...

DESCRIPTION

Run 'autoconf2.72' and, when needed, 'aclocal', 'autoheader2.72', '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 'autoreconf2.72' remake 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 generated and standard files obsolete
-i, --install: copy missing standard auxiliary files
--no-recursive: don't rebuild sub-packages
-s, --symlink: with -i, install symbolic links instead of copies
-m, --make: when applicable, re-run ./configure && make
-W, --warnings=CATEGORY: report the warnings falling in CATEGORY (comma-separated list accepted)

Warning categories are:

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

-W also understands:

all: turn on all the warnings
none: turn off all the warnings
no-CATEGORY: turn off warnings in CATEGORY
error: treat all enabled warnings as errors

Library directories:

-B, --prepend-include=DIR: prepend directory DIR to search path
-I, --include=DIR: append directory DIR to search path

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