macos cross-compilation

[mgovers]

May fix #466 .

We can only test this after attempting to build

@mgovers what do you want to achieve here? We cannot test macOS on arm (only cross compile) in GitHub Actions. They don't have a public M1 runner. The M1 runner large is a paid service for commercial use.

Can we just ask Jean to run the pytest in his laptop?

they should have it now according to https://github.blog/2023-10-02-introducing-the-new-apple-silicon-powered-m1-macos-larger-runner-for-github-actions/ but it doesn't seem to work correctly yet

In addition, we should be able to cross-compile for macos with both x86_64 and arm64 architecture according to https://cibuildwheel.readthedocs.io/en/stable/faq/#arm64

I'm just trying it out now

i will but i've already found out yesterday that he receives all zeros as output from the PGM, which is why i strongly suspect different architectures to be the issue

The M1 runner in GitHub Actions is a paid service even for open-source project.

We already do the cross compilation for a long time. In the macOS build using Intel Mac runner, we build and test x64, and build arm64 but not test it.

Ah ok, that explains.

i see now from the pyproject.toml indeed. Well, one way or another, everything looks like it's borked for M1 processors after this change: https://github.com/PowerGridModel/power-grid-model/compare/v1.6.21..v1.6.22 .

@Thijss Also have run pytest in his M3 macOS. It seems everything runs okay. @Thijss can you comment on that?

pytest result on M3 MacOS on PGM 1.6.53:

[Thijss]

which is somewhat different from 1.6.52:

Here I did git checkout v1.6.52 and pip install power-grid-model==1.6.52

[TonyXiang8787]

pytest result on M3 MacOS on PGM 1.6.53:

The xfail is expected. We have validation test for Newton-Raphshon state estimation. But the core is not ready yet.

The python project has the same issue:

unit tests + validation tests pass on Jean's MacBook. Closing this PR
