Rename works only after goto definition

[jakkarn]

When I open up a C++ file in neovim with coc installed, I can rename or show references of a variable that is defined in a header file but only after I have used go to definition of the variable. Before that, no references are found and rename only works in the local file. Why is this? Is it because I'm missing a compilation database or something else?

I am using Clang as language server installed via the CocCommand.

Should be problem of your language server, checkout https://github.com/neoclide/coc.nvim/wiki/Debug-language-server#using-output-channel

So this is the workspace.showOutput when I open my simple main.cc with a header file that defines a variable. I didn't see any difference in this output after adding "trace.server": "verbose" to the CocConfig file.

Then I apparently get this yarn-error.log in the same directory. I didn't install yarn though, but I thought it wasn't neccesary to use yarn.

The only thing I understand is the compilation database that is missing, but is that neccesary for coc to make rename work on open file? Rename works after goto definition has been used.

It's issue with your language server, not coc.nvim.
