Hi I run "Linux 2.6.11-gentoo-r11 x86_64" and get he following error when issuing "autoheader": autoheader-2.59: error: AC_CONFIG_HEADERS not found in configure.in The first five lines of my "configure.in" are as follows: AC_PREREQ(2.5) AC_INIT(test, [1.0], [hmobahi@xxxxxxxxx]) AM_INIT_AUTOMAKE AM_CONFIG_HEADER([config.h]) AC_CONFIG_SRCDIR([main.c]) I am using AM_CONFIG_HEADER and not AC_CONFIG_HEADERS because I want to use automake and autoconf. I even issued a "aclocal" and then tried "autoheader" again, but it did not help. I appreciate any help about what the problem is and how to fix it. Thnx --Hossein have got stuck in using autoheader for my project: I have just started learning autoconf _______________________________________________ Autoconf mailing list Autoconf@xxxxxxx http://lists.gnu.org/mailman/listinfo/autoconf
