I have a c project and I would like to use the feature of LSP in Neovim such as gd (go to definition).

I follow each of these materials to configure LSP

However, I've encountered some problems.

  1. Following the guide in clangd.llvm.org/installation, I execute sudo apt-get install clangd-10 to install clangd (sudo apt-get install clangd-12 will result in E: Unable to locate package clangd-12 even though I have executed sudo apt-get update). But when I want to check the version of clangd by executing clangd --version, I got Command 'clangd' not found as it is not installed yet.

  2. After executing bear <my_build_command>, I got the complile_command.json. But when I open .c file in the project, I got the information: Spawning language server with cmd: clangd failed. The language server is either not installed, missing from PATH, or not executable.

I think the problem may result from 1. After Googleing the related information and tried to reinstall clangd, clangd --version still result in the same: Command 'clangd' not found.

Do I missing something or what? Any one can give me a help? Thanks.

  • I have the impression that your current problem is more related to the installation of clangd on Ubuntu than related to Vim and the relation between clangd and Vim. I recommend you to contact some clangd knowledgeable people first (although some could also follow this site ;-) ). Commented Jun 29, 2023 at 16:47

    Hi @VivianDeSmedt Thanks for replying. Finally, I fixed it somehow. For someone else might need the information, I follow the answer part of this post, and then clangd --version gives me the version information.

  • Thanks for the follow up. Did you also solved the integration with Vim? Commented Jun 30, 2023 at 3:57

    Yes. In my case, installation of clangd is just the last thing to make LSP working on Neovim.
