[Caml-list] Compiling a file using the Toploop module

[Jean-Baptiste Jeannin <jeannin@cs.cornell.edu>]

Hi all,

I have been using the Toploop module in some code that I have always 
interpreted using the "ocaml" command. I am now trying to compile this 
code using "ocamlc", but I keep getting the following error:

File "try_toploop.ml", line 1, characters 0-1:
Error: Error while linking try_toploop.cmo:
Reference to undefined global `Toploop'


More precisely, this error can be reproduced with a file try_toploop.ml 
containing just the two lines:

module T = Toploop;;
print_int 0;;

It interprets fine with the ocaml interpreter (or as a matter of fact, 
in the toplevel system):
$ ocaml try_toploop.ml
0

However, if I try to compile it, I get:
$ ocamlc try_toploop.ml
File "try_toploop.ml", line 1, characters 0-1:
Error: Error while linking try_toploop.cmo:
Reference to undefined global `Toploop'

I am wondering how to compile such a file using ocamlc, or even if it is 
possible. I have been looking for possible options to include a pointer 
to a toploop.cmo, but could not solve the problem. Thank you for your help!
