13.4.5 configure.ac at top level
configure.ac
or configure.in
- this is the source from which autoconf
generates the configure
script.
Declare the package and version.
This is done by a set of lines like these:
PACKAGE=gettext VERSION=0.21 AC_DEFINE_UNQUOTED(PACKAGE, "$PACKAGE") AC_DEFINE_UNQUOTED(VERSION, "$VERSION") AC_SUBST(PACKAGE) AC_SUBST(VERSION)
or, if you are using GNU automake, by a line like this:
AM_INIT_AUTOMAKE(gettext, 0.21)
Of course, you replace ‘gettext’ with the name of your package, and ‘0.21’ by its version numbers, exactly as they should appear in the packaged tar file name of your distribution (gettext-0.21.tar.gz, here).
- Check for internationalization support. Here is the main m4 macro for triggering internationalization support. Just add this line to configure.ac:
AM_GNU_GETTEXT([external])
Have output files created.
The AC_OUTPUT directive, at the end of your configure.ac file, needs to be modified in two ways:
AC_OUTPUT([existing configuration files po/Makefile.in], [existing additional actions])
The modification to the first argument to AC_OUTPUT asks for substitution in the po/ directory. Note the ‘.in’ suffix used for po/ only. This is because the distributed file is really po/Makefile.in.in.
