Hi All, I'm new to autoconf. I have been building an application which will use autoconf 2.68. autoconf 2.68 is throwing below errors. Please find the errors list below: ======================================================= build_script : Running reautoconf script Autoconf in './ilnclient' configure.in:112: error: AC_LANG: unknown language: ../../lib/autoconf/lang.m4:82: _AC_LANG_SET is expanded from... ../../lib/autoconf/lang.m4:89: AC_LANG is expanded from... /home/panthangi/aaa/aaahpsrc/trunk/server/aclocal.m4:975: AC_CHECK_ALL_TOOLS is expanded from... configure.in:112: the top level autom4te: /usr/local/bin/m4 failed with exit status: 1 ======================================================== If I use autoconf 2.13, the autoconf generates configure scripts without any errors. Could anyone please help me how to resolve these errors in autoconf 2.68 ? And Can I have any tool which will automatically convert the configure.infiles (which were written for autoconf 2.13) from 2.13 to autoconf 2.68. PS: I'm using m4 (GNU M4) 1.4.15 version.and libtool 2.4 version. Thanks in advance. -Naresh _______________________________________________ Autoconf mailing list Autoconf@xxxxxxx http://lists.gnu.org/mailman/listinfo/autoconf
