Add aarch64 windows releases
It would be great to have aarch64 windows builds here -- tools that rely on pbs_installer (such as pdm) are unable to find any python versions to install on aarch64 windows (i.e. Win11 Parallels on a Apple Silicon MBP). Things are detected properly, but the python version list of course doesn't contain any matches:
THIS_ARCH = 'aarch64'
THIS_PLATFORM = 'windows'
Oh hey, I didn't search PRs, just issues; but just found this WIP: https://github.com/indygreg/python-build-standalone/pull/93
I've rebased onto main and am taking a look in https://github.com/indygreg/python-build-standalone/pull/387
This looks blocked by GitHub Actions runner availability https://github.com/indygreg/python-build-standalone/pull/387#issuecomment-2447890742 — unless you have ideas.
Any news on this ? https://github.com/bazelbuild/rules_python depends on this to be able to support python toolchain on windows arm64 (think of all the new laptop using the latest snapdragon soc, surface pro, ...).
I'll look into using paid runners, but I can't do that in this organization. Please see https://github.com/indygreg/python-build-standalone/issues/386#issuecomment-2447892135
ARM on Windows runners are coming to GitHub Actions in the next few months. They're available on private runners now, but I understand that's not an option for most projects. I have a VM as well to test the workflow
They're ~actually available publicly~ (nope that's Linux) available in our org now but the images are missing all the necessary build tools.
@zanieb released it publicly today https://github.blog/changelog/2025-04-14-windows-arm64-hosted-runners-now-available-in-public-preview/
@zanieb any update on this issue ?
The builds are passing, we're just waiting to merge them as we figure out how to handle distributing them downstream, as they the ecosystem isn't ready for them to be the default distribution downstream https://github.com/astral-sh/uv/issues/12906
