How to load a library

[eureka-cpu]

I'm trying to understand how I would add a library, for instance Base (ocamlPackages.base). Adding it to my mkShell doesn't seem to work, which I guess makes sense. How would I add this library so that I can use it?

You add it to the depends of your opam file. opam-nix will pick it up automatically on the next nix develop.

That seemed to at least build, but if I add base to a module with open Base it still says unbound module. Apologies if this is a noob question and I'm just incorrectly trying to load a module.

Can you give me an example repo to see what you are doing exactly?

Was trying to follow along a guide that writes an interpreter and they are using base. Really I'm just trying to get a feel for the language, writing test and using modules.
