MinGW issue - Githubissues

Hey there,

I've been using Neovim with clangd for C and C++, and I'm encountering an issue with my configuration when working with C++ files that include windows.h. While I've set up my configuration file config.yaml to use MinGW compilers without any problem for C files, it seems like clangd can't find windows.h when processing C++ files.

These is my old config.yaml (was working well with c):

CompileFlags:
  Compiler: x86_64-w64-mingw32-gcc
  Add: ["-I../headers", "-I$INCLUDE_PATH"]

Here's my new config.yaml:

If:
  PathMatch: .*\.c .*\.h

CompileFlags:
  Compiler: x86_64-w64-mingw32-gcc
  Add: ["-I../headers", "-I$INCLUDE_PATH"]
---

If:
  PathMatch: .*\.cpp .*\.hpp

CompileFlags:
  Compiler: x86_64-w64-mingw32-g++
  Add: ["-I../headers", "-I$INCLUDE_PATH"]
---

However, when I include windows.h in a C++ file and run clangd, it gives me an error saying that the file is not found:

clangd --enable-config --check=path/to/main.cpp

Now, I encountered an issue with the new config. It's throwing an error message here:

These is neovim LSP log if it's can help.

Do you think this problem is related to my new config? If so, how can I configure clangd to use Mingw compilers for both C and C++? I've tried adjusting the paths and configurations, but haven't had any luck so far. Any suggestions on how to resolve this would be greatly appreciated.

Thanks!
