Integration with emacs org mode?

Has anyone successfully used Ocaml in org mode ? I am able to evaluate simple code in source code blocks, but unable to use modules.

When I evaluate source code block given below :

#+BEGIN_SRC ocaml
  open Some_Module
#+END_SRC

I get :
Error: Unbound module Some_Module

Above code evaluates with no error in normal source code file in spacemacs.

It works fine here.

#+begin_src ocaml
open List
let res = map (fun x -> x+1) [1;2]
#+end_src

#+RESULTS:

2 | 3 |

Where is Some_Module defined?

Sorry I did not test any other module and open List does indeed work. Bad assumption.

I wanted to open Owl module, which does not work.

#+BEGIN_SRC ocaml
  open Owl
#+END_SRC

You probably need to #load the library first.

Thanks brab. I used #require which became available only after #use “topfind” .
So far code blocks below works.

#+BEGIN_SRC ocaml
  #use "topfind" ;;
  #require "owl";;
  open Owl
#+END_SRC

and

#+BEGIN_SRC ocaml :results output
  let m = Mat.uniform 2 2 in
  Mat.(print m)
#+END_SRC

Does all of this imply that Org mode uses the top level to interpret OCaml code and does not run the compiler?
