How to get codelldb on NixOS

1

Is it possible to get codelldb on nixos? If so how? I was not able to find it on search.nixos.org

Yes. https://github.com/DieracDelta/vimconfig/blob/a0493511d5a05e004c8944b8d1a4e251d7a42333/modules/lsp.nix#L324

I tried installing it on MacOS on an M1, but it fails:

nix-shell -p vscode-extensions.vadimcn.vscode-lldb

...
error: could not compile `codelldb` (lib) due to previous error

Ah, yes! It is broken on master nixpkgs. However, there’s a branch of nixpkgs with a working codelldb (and corresponding PR that has not been merged). The fix works great (been using it for several months now with no problems :slight_smile: ). https://github.com/DieracDelta/vimconfig/blob/a0493511d5a05e004c8944b8d1a4e251d7a42333/flake.nix#L16
