Ocaml Error : Unbound module when compiling

Question

I'm learning Ocaml and currently I'm building a graphical interface for a game. I used Graphics and camlimages but now I would like to add some buttons. So I searched for Gtk2 and I'm having problems to compile now. This is a part of my code :

    open Gamebase
    open Game_imp
    open Graphics
    open Graphic_image 
    open Images 
    open Png 

    let _ = GMain.init () 

    let window = GWindow.window 
         ~title:"Simple lablgtk program"
         ~width:320 
         ~height:240 ()

I used

        ocambuild -use-ocamlfind main.ml

before in order to compile combined with _tags file, but in order to include the gtk module, I tried

        ocamlfind ocamlc -g -package lablgtk2 -linkpkg main.ml -o main

which seemed to work in a sample exemple, however when I combine it with my projet, I get "Error: Unbound module Gamebase". I tried

        ocamlfind ocamlc -I +gamebase -g -package lablgtk2 -linkpkg main.ml -o main

but doesn't seem to work. Any hints and kind words are greatly appreciated.

where is the module gamebase is located ? in a specific ml file that is at the same location as main.ml ? — Pierre G.

Simply : ocamlfind ocamlc -g -package lablgtk2 -linkpkg gamebase.ml main.ml -o main

Just take care of the order with which you give the ml file : gamebase.ml must be given first , because main.ml has a dependency on it.
