AUTORECONF(1)

NAME
autoreconf - Update generated configuration files

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

DESCRIPTION
Run `autoconf' (and `autoheader', `aclocal', `automake', `autopoint' (formerly `gettextize'), and `libtoolize' where appropriate) repeatedly to remake 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:

-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

--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 [syntax]

  Warning categories include:

`cross'
    cross compilation issues

`gnu'
    GNU coding standards (default in gnu and gnits modes)

`obsolete'
    obsolete features or constructions

`override'
    user redefinitions of Automake rules or variables

`portability'
    portability issues (default in gnu and gnits modes)

`syntax'
    dubious syntactic constructs (default)

`unsupported'
    unsupported or incomplete features (default)

`all'
    all the warnings

`no-CATEGORY'
    turn off warnings in CATEGORY

`none'
    turn off all the warnings

`error'
    treat warnings as errors

The environment variable `WARNINGS' is honored. Some subtools might support other warning types, using `all' is encouraged.

  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, AUTOHEADER, AUTOMAKE, ACLOCAL, AUTOPOINT, LIBTOOLIZE, M4, and MAKE are honored.
