[Question][Hw2] How to use utop with Llvm?

[woojinnn]

I'm trying to debug my src/domain.ml with utop.
In src directory, when I try to use domain.ml with #use domain.ml;; command, REPL emits this error:

─( 07:01:14 )─< command 2 >────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────{ counter: 0 }─
utop # #mod_use "domain.ml";;
File "domain.ml", line 2, characters 11-23:
2 |   type t = Llvm.llvalue
               ^^^^^^^^^^^^
Error: Unbound module Llvm

How can I troubleshoot this?
