Well, you'd need it if you want backward compatibility (with an older ABI) but, no, you wouldn't need -sysroot just to produce i386 and x86_64 on a 64-bit capable machine running 10.6. Getting back to your previous post: "But I can't seem to get it to work -- it just uses the last architecture specified." Perhaps you're calling ld(1) directly? To link multiple-arch executables (etc), the Apple gcc driver does the dirty work of calling ld multiple times and lipo-ing the results. See the Apple ld(1) man page. -- Ned Deily, n...@acm.org -- http://mail.python.org/mailman/listinfo/python-list
