No arm64 wheels

[joeyballentine]

Pasteboard currently has no arm64 wheels, which can cause installs to fail on M1 MacBooks.

Pasteboard also has no wheels for recent Python versions; they keep adding new ones 😅. As far as I can see, the GitHub provided macOS runners are x86. If you would like to sponsor/provide M1 runners, let me know.

You don't actually need an M1 runner to build for arm64. At least with cmake (which I have been told just runs clang under the hood), you can cross compile for arm64, and with cibuildwheel you can build an arm64 whl file, all on an x64 runner. Here's just one example: https://github.com/joeyballentine/ncnn-vulkan-python/blob/92eab45bd7c3c3392c1d3137898ab461f6d9b591/.github/workflows/release.yml#L286

The project doesn't use cmake. cibuildwheels seems like a cool project, but isn't trivial to integrate. E.g. there is no point building linux or windows wheels. And it's surprisingly complicated under the hood.

I was able to get clang to output a universal object file. But then linking it always produces a single arch shared object. It seems like you either have to output two wheels (one per arch), or fuse the shared objects via lipo. I'm not really sure why this can't be done by the linker... And I'm not really sure how to do this with setup.py/build.py for poetry.

I'm sure it's possible, but right now, I don't have the time to investigate this further.

You don't need to use cibuildwheel to build all those things, you can configure it to just build for a specific platform. Check out the action config I sent you, it's configured for just macos.

As for the universal .so file, you can use cibuildwheel to build a universal2 wheel that can support both. And all cibuildwheel does it runs your setup.py inside its own environment that lets you build these special wheels. It's really not as complex as you make it out to be

Yeah, that's not going to fly. pasteboard is provided as is, and as I mentioned I don't have the time. I'll assume you meant no offence, but I won't be insulted. If you would like to cut a PR for this, please go ahead.

Thanks to #19 and the v0.4.0 release, we now have universal wheels for 3.11 and 3.12. No idea why pypa/build doesn't build them for previous version, but that's a viable workaround now. As a reminder, pasteboard is basically unmaintained ( #18 ).
