Thanks, Harlan. I tried to use AS_HELP_STRING and found that we cannot double quote its parameters. For example, I wrote a testing configure.ac like this: AC_INIT([Foo], [1.0], [root@xxxxxxxxxx], [foo]) AC_ARG_WITH( bar, AS_HELP_STRING([--with-bar=DIR], [[Where to find bar libs]]) ) Then I run autoconf to generate the configure script. But when I run `configure --help' it outputed like this: Optional Packages: --with-PACKAGE[=ARG] use PACKAGE [ARG=yes] --without-PACKAGE do not use PACKAGE (same as --with-PACKAGE=no) --with-bar=DIR Where, to, find, bar, libs Why the HELP string for `--with-bar' was seperated by commas? Anything I did wrong? _______________________________________________ Autoconf mailing list Autoconf@xxxxxxx http://lists.gnu.org/mailman/listinfo/autoconf
