Hi, first, run aclocal, it should install the AC_PROG_LIBTOOL macro to aclocal.m4. Then run autoconf. The info from your preceding mail does not pbring anything new: % 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, The occurences in requests are normal. The occurence in the output.* file indicates that the macro was not expanded, which indicates a problem.
