I don't remember it exactly, but I think you have to use -m32 to tell gcc that you are going to create a 32-bit executable. Cheers
OK, Hi again Try with this to link. I don't know why, but in a single step gcc seemed to not bypass the good options to ld. gcc -o program -m32 -march=i386 -L/usr/lib -L/lib my.o HTH
