Nice! I have a couple other PRs to take care of first but I'll try to look into this PR 'soon-ish'.

[kassane]

In fact, deployment will still need to be improved to avoid artifact conflicts on Linux.
However, it may require adjustments to the fips repo.

[floooh]

The selection of the correct executable happens here:

https://github.com/floooh/sokol-tools-bin/blob/d80b1d8f20fef813092ba37f26723d3880839651/fips-files/generators/SokolShader.py#L18-L35

(e.g. see the code block which selects between the ARM and Intel version on macOS).

We probably don't need to introduce new fips build-configs like on macOS, because it isn't a cross-compilation scenario (as far as I currently understand it).

🤦 now, renamed not found artifact!!!

ci: https://github.com/kassane/sokol-tools/actions/runs/12844591828/job/35817901710

Error: Unable to download artifact(s): Artifact not found for name: linux-ninja-release
        Please ensure that your artifact is not expired and the artifact was uploaded using a compatible version of toolkit/upload-artifact.
        For more information, visit the GitHub Artifacts FAQ: https://github.com/actions/toolkit/blob/main/packages/artifact/docs/faq.md

I also tried rename in dockerfile fips build linux-ninja-release to fips build linux-$(uname -m)-ninja-release, but get error!

[kassane]

fixed and artifacts generated:
my deploy test: https://github.com/kassane/sokol-tools/actions/runs/12846441876

Merge?

[floooh]

There's two different directory names used here:

https://github.com/kassane/sokol-tools/actions/runs/12846441876/job/35821783093

bin/linux_aarch64 vs bin/linux_arm64 (I also noticed this arm64 vs aarch64 mixup in other places, I would suggest using arm64 everywhere to be consistent with the Mac version)

I'll merge the PR but will change all occurances of aarch64 to arm64 (that's what I mean with being consistent to the macos version) :)

Wait... Hasn't it been fixed already? Did I miss something?

[floooh]

I renamed the CI step from linux-aarch64-ninja-release to linux-arm64-ninja-release and the directory name from bin/linux_aarch64/ to bin/linux_arm64/ (while at it I also renamed the step name linux-x86_64-ninja-release to linux-x64-ninja-release.

E..g this commit:

...looking at the CI now to check if everything is working. Thanks for the PR (ah and I'll also add a changelog entry)

Deploy pipeline after merge: https://github.com/floooh/sokol-tools/actions/runs/12870826429

[floooh]

OK i guess that worked:

(be aware though that the new exec is under bin/linux_arm64, not bin/linux_aarch64)

[floooh]

@kassane do you have a linux-arm64 machine around? I thought I could use my old Raspi but that's only 32-bits :)

If yes, could you check in python3 what's returned here?

import platform
platform.machine()

(on ARM Macs this returns the string arm64 but I wonder what's returned on Linux).

This is needed to fix the executable selection here:

https://github.com/floooh/sokol-tools-bin/blob/176fe04861f57921a365853964961b3f29f24363/fips-files/generators/SokolShader.py#L18-L35

[kassane]

o you have a linux-arm64 machine around?

@floooh , my rpi4b

Oki thanks, I also get aarch64 in a Linux ARM64 Docker image. But I guess I will just check against both arm64 and aarch64 just to be sure:
