Regular Expressions in OCaml
I want to use regexps in OCaml and it seems that Str module provides these functionalities.
So I tried with a simple program:
open Str
let regx = regexp "."
but it gives me the following error
File "lol.ml", line 1, characters 0-1: Error: Error while linking lol.cmo: Reference to undefined global `Str'
As if module is not present but if I remove open Str it says that regexp is an unbound value.
I don't get what kind of issue it is, Str should be a standard module (according to http://caml.inria.fr/pub/docs/old-311/libref/Str.html) so I'm clueless.. the only think I thought is that signature (mli) is present but implementation (ml) is not.
I'm running Objective Caml version 3.11.0 according to ocaml tool.
Can anyone help me figuring this out? Thanks in advance

From the manual:
Programs that use the str library must be linked as follows:
ocamlc other options str.cma other files ocamlopt other options str.cmxa other files
