Problem with setup llvm-mos on Windows

[grakoczy]

Hi,

I've just built Picocomputer and configured C665 without any problems. I can build samples and games and all works just fine.
Then I've tried to do the same with MOS-LLVM but with no luck.
I've installed it according to instructions from https://github.com/llvm-mos/llvm-mos-sdk/blob/main/README.md.
When I try to compile example code using command
.\mos-rp6502-clang.bat -Os -o hello.prg ..\examples\hello-getchar.c it works fine.

The problem is when I try to build the code from LLMV template project.
When I select Unspecified for cMake kit it got error:

[main] Building folder: c:/workspace/picocomputer/vscode-llvm-mos-template/build [build] Starting build [proc] Executing command: chcp [proc] Executing command: "C:\Program Files\CMake\bin\cmake.EXE" --build c:/workspace/picocomputer/vscode-llvm-mos-template/build --config Debug --target ALL_BUILD -j 26 -- [build] Microsoft (R) Build Engine 16.11.2+f32259642 dla platformy .NET Framework [build] Copyright (C) Microsoft Corporation.

So I've tried to find kits. It finds llvm but for unknown platform:

[proc] Executing command: C:\llvm-mos\bin\clang.exe -v [kit] Found Kit (trusted): Clang 20.0.0git mos-unknown-unknown [kit] Found Kit (trusted): Visual Studio Build Tools 2019 Release - x86 [kit] Found Kit (trusted): Visual Studio Build Tools 2019 Release - x86_amd64 [kit] Found Kit (trusted): Visual Studio Build Tools 2019 Release - amd64_x86 [kit] Found Kit (trusted): Visual Studio Build Tools 2019 Release - amd64 [kit] Successfully loaded 5 kits from C:\Users\grako\AppData\Local\CMakeTools\cmake-tools-kits.json

Then if I try to switch to mos kit I see the error:

Is there anybody who configured LLVM on windows machine?

Hi,
I've finally resolved this problem installing llvm-mos under WSL2 and using remote development.
