Hello list, Some experts on the GSL (GNU Scientific Library) mailing list pointed me to this mailing list. I am having troubles checking for the appropriate library when linking to the GSL library (I wanted to use custom blas libraries, like ATLAS or MKL). Although I already have it working now, I do not know why I had this particular problem. Perhaps one of you know the answer? First of all, the version of autoconf I am using appears to be: $ autoconf --version autoconf (GNU Autoconf) 2.61 Now, if I would use the recommended way to link to the GSL library with the GSL blas library, I would write in my configure.ac: AC_CHECK_LIB(m,main) AC_CHECK_LIB([gslcblas], [cblas_dgemm]) AC_SEARCH_LIBS(gsl_atanh, gsl) Which gives: checking for main in -lm... yes checking for cblas_dgemm in -lgslcblas... yes checking for gsl_atanh in -lgsl... yes However, the following should also work: AC_CHECK_LIB(m,main) AC_SEARCH_LIBS(gsl_atanh, gsl, [], [], -lgslcblas) Which gives: checking for main in -lm... yes checking for gsl_atanh in -lgsl... no The GSL guy that pointed me towards this list did the same thing, and there he had a 'yes' on the last line. Does one of you know what the problem there is/could be? Thanks! Rutger ps. I am not on this mailing list, so please CC me in your reply _______________________________________________ Autoconf mailing list Autoconf@xxxxxxx http://lists.gnu.org/mailman/listinfo/autoconf
