13.4.6 config.guess, config.sub at top level

If you haven’t suppressed the intl/ subdirectory, you need to add the GNU config.guess and config.sub files to your distribution. They are needed because the intl/ directory has platform dependent support for determining the locale’s character encoding and therefore needs to identify the platform.

You can obtain the newest version of config.guess and config.sub from the ‘config’ project at http://savannah.gnu.org/. The commands to fetch them are

$ wget -O config.guess 'http://git.savannah.gnu.org/gitweb/?p=config.git;a=blob_plain;f=config.guess;hb=HEAD'
$ wget -O config.sub 'http://git.savannah.gnu.org/gitweb/?p=config.git;a=blob_plain;f=config.sub;hb=HEAD'

Less recent versions are also contained in the GNU automake and GNU libtool packages.

Normally, config.guess and config.sub are put at the top level of a distribution. But it is also possible to put them in a subdirectory, altogether with other configuration support files like install-sh, ltconfig, ltmain.sh or missing. All you need to do, other than moving the files, is to add the following line to your configure.ac.

AC_CONFIG_AUX_DIR([subdir])
