I’m not sure I understand what you’re asking. It seems like you’re asking why your clangd extension isn’t working? But then you say:

BTW I’m not talking about using clangd with the vscode flatpak package

If you’re on Linux chances are using a package manager. Do you think the package maintainers won’t compile the features(well maybe, Debian)? It still makes no sense as most users would have the feature anyway.

Bro it’s so damn hot here, no idea how you do it. Respect though!
