Cannot access configuration for clangd

[coder1044324]

Before I open a .cpp file, the following error comes up.
[lspconfig] Cannot access configuration for clangd. Ensure this server is listed in server_configurations.md or added as a custom server.
I have ensured that the server is indeed listed in the file, and also that Mason.nvim has installed it. Any ideas for a fix?

Thanks

Also how I could go about getting better syntax highlighting for cpp? If I'm not mistaken highlighting would be independent of this other problem right?

Yes, highlighting is controlled by treesitter and not lsp, but lsp gives you diagnostics.

For the 1st question, I'm not really sure if this helps but since I use Android, I think there are some libc differences that made some lsps not work correctly. I have clangd from Termux packages (couldn't install via mason) and it is in the path, but neovim doesn't detect it. I couldn't build from source either but I managed to find a workaround. I installed coc-clangd via coc-nvim and now the lsp works. You can disable coc-nvim via lazyload or whatever and the lsp will still be attached.

It seems to be working on my end, are you sure you have the :lang cc module enabled? We use https://github.com/p00f/clangd_extensions.nvim to setup the clangd language server in order to get more language-specific features (inlay hints, ast/memory info, etc.).

First run ls ~/.local/share/nvim/mason/bin and check if clangd is in the list of executable binaries. If thats all good, then open up a c or c++ buffer and run :LspInfo, check if the clangd server is configured or not and if neovim can find it.

We use nvim-treesitter for syntax highlighting. Enabling the cc module and telling nyoom sync to install all tree sitter parsers should install the c and c++ parsers. Try running TSPlayground in a c or c++ buffer and lmk if it works or not

Thanks, will try this if other stuff doesn't work!

Just double checked and the module is definitely enabled. clangd is in the list at ~/.local/share/nvim/mason/bin, however :LspInfo doesn't show clangd configured for some reason.

TSPlayground does work..

Also happens to me.
It just happens in a clean install of the nyoom.

It seems like i can reproduce the issue doing the following:

I can also get another error doing the following:

1. Delete ~/.local/share/nvim
2. NyoomSync with cc disabled
3. NyoomSync with cc enabled
4. Open a file with either .c or .cpp

WIth this, when i first open nyoom, i get the follwing:

packer.nvim: Error running config for clangd_extensions.nvim: ...pt/clangd_extensions.nvim/lua/clangd_extensions/init.lua:9: module 'lspconfig' not found:

	no file '/home/fushi/.cache/nvim/packer_hererocks/2.1.0-beta3/lib/lua/5.1/lspconfig.so'

After that, the issue descbried in this post keeps happening everytime nyoom is opened.

#121 Should probably fix this. @coder1044324
