how to set coc config clangd.path to wsl clangd in windows , because win version clangd.exe always crash

[WillDawnlll]

i test these configs , and all not work :
1 . set "clangd.path" to "wsl clangd" ,
2. set "clangd.path "\wsl$\Debian\usr\local\bin\calngd" ,
3. or "d:/tool/wsl_clangd.bat" (just "wsl clangd")

i not familiar with js , but simply check the code , may be the reason is clangd execute bin path append ".exe" in windows ?

I would like to do something similar. Except that my approach would be to make clangd.exe work since the code base I'm compiling has some windows exclusive instructions, therefore I need Windows' clangd to work. I can't use WSL's.

I get this log when I try to open some C++ file:

with the following config:

CocLocalConfig

{
    "languageserver": {
        "clangd": {
            "command": "/mnt/c/Program\\ Files/LLVM/bin/clang.exe",

            "filetypes": ["c", "cc", "cpp", "c++", "objc", "objcpp"]
        }
    }
}

I've just realized that my config did not make use of coc-clangd. However, I tried:

{
    "clangd": {
        "path": "clangd.exe"
    }
}

but I got the following message:

[coc.nvim] clangd was not found on your PATH. :CocCommand clangd.install will install 14.0.3.

I also tried with:

"path": "/mnt/c/Program\\ Files/LLVM/bin/clang.exe"

and it didn't change anything.

Sorry I don't have a Window env to test.

@sim590 if you run nvim server on the wsl, then you can use msys clangd.exe on the windows side

which clangd
/mingw64/bin/clangd
