Hello There seems to be some problem with my inscription on this list, since i could send this message yesterday but did not receive the answer. I looked at the archives to find out I had this answer; so sorry for writing back so late. So if someone care to answer this post, please include my address as Gcc Allin Cottrell: On Mon, 11 Oct 2004 jean.magnanb at univ.u-3mrs.fr wrote: ../lib/.libs/libgretl-1.0.so -ldl -L/usr/local/lib \ /usr/lib/libxml2.so -lpthread -lz -lm \ /usr/lib/libglib-2.0.so -lreadline -lcurses These are fortran-related references that are undefined. Somehow you're missing a link to libf2c (and probably lapack too). Can you take a look at your config.log, and see what it says after "checking for LAPACK"? You could also look for the line starting "LAPACK_LIBS =" in the Makefile in the lib directory, and see what it says. Well, what I did with LAPACK_LIBS is I had to define it for the ./configure to happen, it was apparently no where expected: "LAPACK_LIBS =/usr/lib/liblapack.a ./configure", and then configure happened all right. Maybe I should say the same for make?
