@chadchoi Anyway, since you got the latest version of Geany running, you should be able to test the LSP plugin by getting the artifact from
https://github.com/geany/geany-plugins/actions/runs/12283983695/
and installing geany-plugins from there (no need to install Geany itself, you'd have to fight with the libstdc++ problem again).
As far as I can tell, it works, but I didn't use it for real development so I'm interested in any feedback.
I have your version up and running. We should continue the discussion about it on #4082.
