| + | If you have a recent Mac with 64-bit EFI, and intend on making an EFI binary to run on it, you will need a 64-bit cross compiler. I don't know of any automated way of getting one, so you'll have to build it yourself following the instructions at http://wiki.osdev.org/GCC_Cross-Compiler_for_x86_64 --- good luck! | ||
