Linux arm builds

[axu2]

Looks like GitHub will add Linux ARM64 runners this year,

Hello,

I am not sure on how to use the new arm64 runners but it is already possible to build for this architecture using qemu:

• https://cibuildwheel.pypa.io/en/stable/faq/#emulation

I will try to have a look at this when I have some time :)

The arm runners are not available yet for general users, but it should be as simple as adding another os to the matrix here:

      matrix:
        os:
          - ubuntu-22.04
          - windows-2019
          - macos-11

Should be available later this year.

I was able to build ARM64 packages using qemu. I think we will build arm packages this way waiting for native ARM64 runners to be available for everyone.

---

I also found that macOS builds were not running anymore (fixed by upgrading from macOS 11 to 12) and that Windows builds were broken (fixed after many tests by sticking to setuptools<74)....

---

A new release of this package will be done when Python 3.13 will be out. ARM64 packages will be available at the same time on PyPI :)

Thanks! While we are at it, can you add armv7 too?

I tried for ARMv7 but I had the following error:

ValueError: 'armv7l' is not a valid Architecture

cibuildwheel lists this architecture in their table... but only for musllinux target (that's maybe why it failed):

• https://cibuildwheel.pypa.io/en/stable/

I don't searched further but if you have info on how to make the build for this arch I could have a look. :)

I think you need to bump the cibuildwheel version too.

And maybe you need an arm64 runner...

v1.1.4 released, the build of the wheels is in progress and should be available soon. The ARM64 wheels for Linux will be available at the same time.

I close this ticket as it is resolved. Maybe you can open an other one for the armv7 target if it matter :)
