I'm guessing these instructions are for the apple gcc? Because doing this with the gcc / gfortran that I've been installing with macports gives gcc-mp-4.8: error: unrecognized command line option '-arch' and trying to compile C code on Mountain Lion with the apple gcc gives llvm-gcc-4.2: error trying to exec '/usr/bin/../llvm-gcc-4.2/bin/powerpc-apple-darwin11-llvm-gcc-4.2': execvp: No such file or directory llvm-gcc-4.2: error trying to exec '/usr/bin/../llvm-gcc-4.2/bin/powerpc-apple-darwin11-llvm-gcc-4.2': execvp: No such file or directory So I'm concluding it is impossible to build universal fortran apps since the apple gcc doesn't come with gfortran. My only hope would be to build separate binaries for each architecture by: 1. access to old OS X machines (+ macports) 2. cross compile I don't have access to old machines (and it would be incredibly inconvenient in any case), and I'm guessing macports doesn't supply cross compilers for older OS X architectures. _______________________________________________ macports-users mailing list [email protected] https://lists.macosforge.org/mailman/listinfo/macports-users
