I am new to NixOS. I found that my Neovim configuration works directly on NixOS, but soon I discovered some issues. I need to use clangd as the LSP to check my C++ code and support features like code navigation. However, no matter where I place the compile_commands.json file, clangd does not seem to recognize it. As a result, it fails to support syntax checking and symbol navigation—for example, it cannot even jump into <iostream>.
How can I make clangd work on NixOS just like on a regular Linux distribution? Do I need to use home-manager? I am not a fan of this approach because I prefer to keep my Neovim configuration unified across different Linux distributions rather than customizing it specifically for NixOS. Can something like nixvim solve this problem?
