Anybody know how to fix ycm (clangd?) for find STL files?

Also I see in YcmDebugInfo :

-- Server has Clang support compiled in: False
-- Clang version: None

but clangd is running. Is it OK?

I have try to reconfigure ycm by run 'python3 install.py --clangd-completer'. I have try to use system clangd by configure g:ycm_clangd_binary_path. Anyway ycm doesn't find STL files.

    Use the plugin's official support channels. – romainl Apr 09 '23 at 17:15
  • I found the solution myself. The problem reason is clangd can't find headers in /usr/include/c++/11/ Some details of the environment: the compilator is accessible by /usr/bin/g++ . The STL library is accessible by /usr/include/c++/11/ . Solution: add to .vimrc `let g:ycm_clangd_args = [ '--query-driver=/usr/bin/c++' ]` There are g:ycm_clangd_args is the ycm option for add flags to clangd, --query-driver is the clangd flag for find STL, /usr/bin/c++ is magic string clangd find STL in /usr/include/c++/11/ – Vasilii Apr 16 '23 at 08:55
  • Well, make it an answer. – romainl Apr 16 '23 at 09:21
