Unbound module error from accessing locally defined modules

Hi, I’m a bit new to OCaml, trying to write a BrainF interpreter with it currently. I’m getting an “unbound error module” error when opening an .ml file into another. For example when I run this in dune utop

utop # #use "evalbf.ml";;
File "evalbf.ml", line 2, characters 5-12:
2 | open Parsebf
         ^^^^^^^
Error: Unbound module Parsebf
Hint: Did you mean Parsing?

I also got the same error when compiling with ocamlopt . However dune build runs just fine and doesn’t produce the error. Also, I tried to run dune clean && dune build but the error still persists. Is there a step I’m missing or maybe some bug?

Thanks in advance!

(also i’m not sure if this has anything to do with it but i’m doing the ocaml project inside a nix shell environment, apologies if this isn’t the right place for it)

It depends on your project structure. If your Parsebf module is in a wrapped library, you probably need to access it as Libraryname.Parsebf.
