printing the AST of a caml function

[Zorg 421 <zorglub421@gmail.com>]

Hello,

I want to play/understand the caml AST, so I try using this code snippet:

---
let factstring = "let rec fact n = if n < 1 then 0 else n * fact (n-1)" in
let tree = Parse.implementation (Lexing.from_string factstring) in
Printast.implementation (Format.formatter_of_out_channel stdout) tree
---

and this build script (~15 minutes spent in ordering correctly the .cmx :-/ )

---
#!/bin/sh
ocamlopt -I /opt/godi/lib/ocaml/compiler-lib/ misc.cmx linenum.cmx
warnings.cmx location.cmx lexer.cmx syntaxerr.cmx config.cmx
clflags.cmx parser.cmx parse.cmx printast.cmx lexing.cmx format.cmx
factast.ml -o factast
---

But the linker is confused by the Lexing module of stdlib:

Files /opt/godi/lib/ocaml/std-lib/lexing.cmx
and /opt/godi/lib/ocaml/std-lib/stdlib.cmxa both define a module named Lexing

How can I prevent the linker to look in /opt/godi/lib/ocaml/std-lib/
or /opt/godi/lib/ocaml/std-lib/stdlib.cmxa ?

regards.
