With a bit of digging I can see that the configure.ac file that (on a machine that demonstrates this problem) autom4te sees:
% cd autom4te.cache/ % grep AC_PROG_LIBT * output.0:AC_PROG_LIBTOOL output.1:AC_PROG_LIBTOOL output.3:AC_PROG_LIBTOOL requests: 'AC_PROG_LIBTOOL' => 1, requests: 'AC_PROG_LIBTOOL' => 1, requests: 'AC_PROG_LIBTOOL' => 1, requests: 'AC_PROG_LIBTOOL' => 1, % so AC_PROG_LIBTOOL is clearly there, but seems to be "weeded out" from later runs. I contrast this with a different configure.ac on that same machine, which shows: % cd autom4te.cache/ % grep AC_PROG_LIBT * output.0:AC_PROG_LIBTOOL output.1:AC_PROG_LIBTOOL output.2:AC_PROG_LIBTOOL output.3:AC_PROG_LIBTOOL output.4:AC_PROG_LIBTOOL requests: 'AC_PROG_LIBTOOL' => 1, requests: 'AC_PROG_LIBTOOL' => 1, requests: 'AC_PROG_LIBTOOL' => 1, requests: 'AC_PROG_LIBTOOL' => 1, requests: 'AC_PROG_LIBTOOL' => 1, % What can I do to debug this problem? I'm running automake 2.59. H _______________________________________________ http://lists.gnu.org/mailman/listinfo/libtool
