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'

   `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  AUTOM4TE,  AUTOCONF,  AUTOHEADER,  AUTOMAKE,
   ACLOCAL, AUTOPOINT, LIBTOOLIZE, M4, and MAKE are honored.
