This is the first of a few MRs I have planned to support Craft builds for MacOS arm64 (M1).
I currently have an arm64 KDE Connect building under Craft, so this is possible 🥳
This one is pretty simple; I thought it would be good to get the naming of the abi & craft compiler methods agreed upon (as well as the general idea of supporting arm64 mac builds) before I tidy up the rest of my changes.
- Add a warning that compiling arm64 is experimental?
- Use the new method for detecting a arm64 build to add relevant compiler flags to
- Add patches to blueprints that don't yet have M1 support (pixman, which has an upstreamed commit to do this and libpng, which does not)
- And various other blueprint problems (can't use
SSE2in libfftw, openssl and qtbase need some fixes to manually compile themselves)
