I'm desperately stuck with the following issue: I = fail to compile a program using a module, but have no problem using the mod= ule in question in the toplevel.

Here is how I use it in the topleve= l

$ ocaml
=A0=A0=A0=A0=A0=A0=A0 Objective Caml version 3.12.1<= br style=3D"font-family:courier new,monospace">
# #directory "/home/pveber/usr/ocamlbrew/ocaml-= 3.12.1/lib/ocaml/site-lib/R";;
# #load "/home/pveber/usr/ocamlbrew/oc= aml-3.12.1/lib/ocaml/site-lib/R/R_math.cma";;
# Rmath.pow;;
- : float -> float -> float =3D <fun><= br style=3D"font-family:courier new,monospace">

Now with the following program:
$ cat test.ml
let x =3D Rmath.pow 2.

I try to compile with the options corresponding to the toplevel directi= ves:

$ ocamlc -o r= math -I /home/pveber/usr/ocamlbrew/ocaml-3.12.1/lib/ocaml/site-lib/R /home/= pveber/usr/ocamlbrew/ocaml-3.12.1/lib/ocaml/site-lib/R/R_math.cma test.ml
File "test.ml", line 1, characters 8-17:
Error: Unbound module Rmath

I'm missing something obvious, but I can't see what. Does it re= mind someone of something?

Cheers,
=A0 Philippe.
