Well, for a detailed answer one needs to see the config.log contents for this error. > Could you do likewise for Fortran? You can do that yourself, for Fortran 77: s/C++/Fortran 77/g s/CXX/F77/g s/cxx/f77/g and Fortran: s/C++/Fortran/g s/CXX/FC/g s/cxx/fc/g Cheers, Ralf _______________________________________________ Autoconf mailing list Autoconf@gnu.org http://lists.gnu.org/mailman/listinfo/autoconf
