This is really strange because our CI works fine. Are you sure you haven't made any modifications to the project files after generation?

[bmahlbrand]

definitely, I also tried cloning fresh a couple of times and had the same error. I'm sure there's something I overlooked on my end.

Not sure what it could be either..

You can check if the archives for LLVM are properly extracted in the LLVM build path: /mnt/c/Users/user/workspace/CppSharp/build/llvm/llvm-0c8f9b-linux-x64-gcc-9-*

Also check the verbose build output (you can invoke make/build with verbose=true make, it should give you the actual compiler parameters being passed by the makefile. If you can paste it on a gist or something then I can take a look.
