Don’t

Don’t use clangd exe downloaded by clangd extension in vscode.
Don’t need tasks.json like files.

Steps

Install msys2 https://www.msys2.org/
Install C++ toolchain

1
pacman -Syu
2
pacman -S mingw-w64-x86_64-gcc
3
pacman -S mingw-w64-x86_64-cmake # use cmake --build ., no need make
4
pacman -S mingw-w64-x86_64-clang
5
pacman -S mingw-w64-x86_64-clang-tools-extra # clangd is here

Find your clangd.exe in C:\msys64\mingw64\clangd.exe
Put the path in your vscode clangd settings.

Done.

Test

Create unix like cmake project
cd build
cmake ..
Reload vscode window and see if it can find headers

If you want lsp without cmake

Add this two flags to your vscode clangd fallback flags:

1
-IC:/msys64/mingw64/include/c++/14.1.0
2
--target=x86_64-w64-windows-gnu

check if a single file can find headers.

(Tested ok)

Use ninja

In msys2:

1
pacman -S mingw-w64-x86_64-ninja

Write cmake as usual. ref: https://blog.51cto.com/u_15127539/3336648

1
cd build
2
# I forget if I need to specify "build for ninja". This just works on my win10 now
3
cmake ..
4
ninja install

Go to install/bin/ and check generated executable.
