November 2022
I finished implementing the old-style macros (comparison to trunk) and GCC and GFortran (except for 6 and older) now build. There are still many failing builds, some of these seem related to the builds running under Rosetta2 but there are other problems. RustC is failing to build (a bootstrap stage compiler is exiting unsuccessfully), Python’s requests is failing to build due to CFFI (Could this be related to #187636, since these builds are running under Rosetta2 on aarch64-darwin?), Libepoxy is another common dependency failing due to a segmentation violation. So lots of issues to figure out, if anyone feels like they may be able to help, feel free to reach out.
This month marks an end to my Nix 
macOS sponsorship. I’m grateful for having had the opportunity to focus on Nixpkgs development for macOS. Going forward I won’t be able to spend as much time on this but I do want to finish the bump. If you’re short on time but want to help out the situation for Nix on macOS, consider contributing financially to the Open Collective.
Happy Holidays and a great 2023 to everyone!
