Hello all. I have just installed automake 1.10 and autoconf 2.61 on my system. I am developing a package which uses GNU Autotools and the configure.ac file for my package contains the following line ; AC_PROG_LIBTOOL When I run autoconf it complains, giving me the following message ; configure.ac:57: error: possibly undefined macro: AC_PROG_LIBTOOL If this token and others are legitimate, please use m4_pattern_allow. See the Autoconf documentation. In response to this message I placed the following line in my configure.ac file ; m4_pattern_allow([^AC_PROG_LIBTOOL$]) Now autoconf doesn't complain. But when I run the resulting configure script I get the following message ; /home/craig/source_code/c++/src/nana/configure: line 3420: AC_PROG_LIBTOOL: command not found The AC_PROG_LIBTOOL macro never used to cause a problem before when I used earlier versions of autoconf and automake. Have I done something wrong or has something changed in the latest version of the Autotools that I should know about? Any help on this matter would be greatly appreciated.Thanks in advance for any help. - Craig Sanders _______________________________________________ Autoconf mailing list Autoconf@xxxxxxx http://lists.gnu.org/mailman/listinfo/autoconf
