@Nexesenex Does this fix your issue?

Not yet, @ikawrakow.

I now get this in the file llama.cpp:

[ikawrakow]

That's not actual ik_llama.cpp but rather your modified fork, or?

[Nexesenex]

That's not actual ik_llama.cpp but rather your modified fork, or?

I tried to compile the main branch, same result. :/

[ikawrakow]

@Thireus I see you are trying to fix the Windows build of the main branch. Have you tried this PR?

[Thireus]

Ah! Thanks for pointing this out: yes I've been trying to switch to MSVC flags to use the experimental version of openmp but without success so far. I'll try this PR.

[Thireus]

Looking good so far, it's compiling. We'll see if it produces release builds in a few hours - https://github.com/Thireus/ik_llama.cpp/actions/runs/20555781303
