I don't know, but I would suspect that your problem is in using '-arch x86_64' and '-march=nocona'. As I understand the first means "build this for the full range of present and future Apple 64 bit Intel hardware and, if specified, lipo it up into a fat binary' While the second means 'optimise this for nocona architecture.' I would have thought you could combine -march nocona with -m64, but combining it with -arch x86_64 might just confuse the compiler. Bill
