Hi, I made two patches to be able to compile ghemical locally on my amd64 with gcc-4.1.1. The libghemical patch works along with a patch I attached to the mopac7 site at sourceforge. The ghemical patch might be wrong, but anyway, -lglut is a necessity for me and teh MAIN__ stuff is needed when using libf2c Cheers, Jean -------------- next part -------------- A non-text attachment was scrubbed...
