[opensuse-factory] Heads up regarding WSL and Windows for ARM cross compilation effort.
Hello openSUSE! I would like to raise awareness about the effort which is currently happening for openSUSE's Windows Subsystem for Linux (WSL) on ARM. Guillaume is currently working on the cross-compiling effort for WSL- DistroLauncher on ARM utilizing LLVM instead of GCC that doesn't support Windows for ARM build target. WSL-DistroLauncher is the missing part to build WSL images for aarch64 in OBS. There were some cases where Guillaume's submit requests were rejected and therefore delayed because people referred to the missing support case with GCC/arm64 for Windows. And this is why we need to spread the word. Why is it important? WSL on ARM is not the highest priority item for Guillaume, and we are happy that he found time to work on this effort all, so we want to avoid any delay as it significantly slows down the progress. For those who are interested in helping Guillaume: https://build.opensuse.org/project/show/home:Guillaume_G:WSL https://bugzilla.suse.com/show_bug.cgi?id=1162960 Thank you very much in advance!

The requests were rejected because they broke combinations such as host=powerpc64-suse-linux-gnu target=(AMD64 PE) -> uninstallable host=aarch64-suse-linux-gnu target=(AMD64 PE) -> output target format erroneously changed // an end-user can no longer generate an amd64 WSL loader from an aarch64 system. That is not acceptable and was already communicated in the SRs of that time, https://build.opensuse.org/request/show/816852 . So please don't suggest that the mingw project could be the cause of any eventual delays, thank you. -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org

Do you really expect people to build for x86_64 windows on PowperPC or Arm machines? I really think it is ok to build for aarch64 windows on aarch64 and for x86_64 windows on x86_64. We build openSUSE for aarch64 on aarch64 and openSUSE for x86_64 on x86_64 after all. I do not see any added value at all to keep the ability to build x86_64 windows on non x86 archs. Cheers, Guillaume

This is called cross-compilation and it's a very valuable thing. I don't understand the reasoning behind to remove such a functionality.

The problem is the prefix of packages: 'mingw64-' applies for windows 64-bit and covers both x86_64 and aarch64. Guillaume

No! In packaging context, "mingw64" does not have *any* meaning except to avoid naming clashes with other packages in the distribution. -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org

Kudos to Guillaume for the immense work he does really, but you do realise that "we are happy that <they> found time to work" on anything openSUSE-related is indeed true of all voluntary contributors who contribute to the project in any way they can, right? I can understand WSL on ARM may be an especially important direction for the distro and thus this email... but the release manager essentially saying "don't reject someone's request" because he/she found the time to do this sounds to me like steam-rolling over potentially valid issues project/pkg maintainers may have with his/her submit requests. But perhaps I am misinterpreting you? Sorry if so, and thanks in advance for any clarification.

I think the meaning was more: "Please help to move forward on this topic". And also to make people aware that WSL on Arm is already there and if people want to help to build openSUSE for WSL, they are more than welcome! Cheers, Guillaume
