I don’t think it is. You wrote: > [2] The string "x86_64-darwin" is used by Nix (it also shows up in some > Guix files), and it seems to be synonymous with "x86_64-apple-darwin". > If you run a command like "gcc -dumpmachine" on a recent version of > macOS, you'll see something like "x86_64-apple-darwin16.7.0". AFAIK on macOS “gcc” and “g++” are just aliases for clang. In order to build a version of GCC that can build binaries for macOS you need XCode or parts of it (the libraries it provides). There is no usable port of the GNU C library for Darwin, so you must link with the non-free C library provided by XCode. This means that step 1 won’t work. The C library abstracts away the peculiarities of the kernel. Without a maintained port of the GNU C library for Darwin I see no way to build software targeting macOS without XCode. -- Ricardo GPG: BCA6 89B6 3655 3801 C3C6 2150 197A 5888 235F ACAC https://elephly.net
