f2c. IRAF uses memory tricks that I don't know how to port to gfortran. Also for f2c to work, I had to use the original f2c.h. Fedora uses a modified f2c.h that has different bit sizes for some of the types that caused a lot of problems. _______________________________________________ Fedora astronomy mailing list astronomy@xxxxxxxxxxxxxxxxxxxxxxx http://fedoraproject.org/wiki/SIGs/Astronomy https://admin.fedoraproject.org/mailman/listinfo/astronomy
