@bjorn3 do you have recommendations for installing a linker that works here?

[bjorn3]

https://www.mingw-w64.org/downloads/#llvm-mingw points to https://github.com/mstorsjo/llvm-mingw/releases for getting an LLVM based MinGW toolchain. I think https://github.com/mstorsjo/llvm-mingw/releases/download/20250709/llvm-mingw-20250709-ucrt-x86_64.zip would work. You need to configure the bin/clang.exe binary inside this zip as linker.

hmm, so no it does not work?

You may need to add the right lib directory to the PATH env var. Note: Windows uses ; as separator, not :. On Windows PATH also acts as equivalent of LD_LIBRARY_PATH on Linux.

[bjorn3]

This should be the x86_64 path, not the armv7 library path, right

[folkertdev]

eh yes. but also I don't think writing to the github_path would actually have much effect here.

clearly, I have no idea what I'm doing here, and it's tough to debug in CI

[folkertdev]

well, idk, feel free to give this a go but it's very user-hostile. Does anyone use this stuff?
