My ARM64 build generates an x86_64 build

[sontek]

Hello, I'm trying to get ARM64 builds published for M1 builds. I have this github action:

https://github.com/sontek/tfparse/blob/fix-arm64-builds/.github/workflows/release.yml#L31-L59

When it runs it does:

CPython 3.10 macOS arm64 - Apple Silicon

Installing Python cp310...

...

    Created wheel for tfparse: filename=tfparse-0.2.0-cp310-cp310-macosx_11_0_x86_64.whl size=6921462 sha256=6e2fa98c54725651d0d6bf1dc8f79e59530affc9c58f1d16a597278e91e5144a

When I expected an arm64 wheel. Am I doing something wrong here?

This is the full action:

I see that your build backend is poetry, and that is invoking setuptools in build.py. I haven't seen this setup before, but the first thing to check is the env vars we set for cross compilation - _PYTHON_HOST_PLATFORM and ARCHFLAGS - check they're reaching setuptools. I wonder if poetry is fiddling with them for some reason.

Thanks! I'll dig into that to see if I can see any issues. I also just attempted to rip out setuptools completely and I'm still seeing the problem:

https://github.com/sontek/tfparse/blob/fix-arm64-builds/build.py#L11-L42

With this build:
https://github.com/sontek/tfparse/actions/runs/3288591323/jobs/5419110550

Could it have something to do with pyproject.toml instead of setup.py driving things? With setuptools completely ripped out I'd expect the wheel to do the right arch?

Looks like the problem might be related to:

python-poetry/poetry#2051
