• Neither actually, I think the issues I encounter happened before the llvm/clang packages get renamed to llvmPackages_16.* and one of the approach I did was adding the nix-shell initialization into .bashrc at the time to workaround my ignorance of NixOS.

    There weren’t a lot of documentation to address my troubles with NixOS at the time, so yesterday evening, I reinstalled NixOS on a VM and started on reading up documentation to re-learn NixOS and trying to get it working. It still confusing however, but I’m taking my time to learn NixOS with a honest try.
