]> I am trying to learn to use camlp4. I started by working my way through the tutorial at http://www.ocaml-tutorial.org/camlp4_3.10/foreach_tutorial I created the file : open Camlp4.PreCast open Syntax EXTEND Gram expr: LEVEL "top" [ [ "for"; v = a_LIDENT; "in"; m = a_UIDENT; e = expr; "do"; seq = sequence; "done" -> <:expr< $uid:m$.iter (fun $lid:v$ -> $seq$) $e$ >> ] ] ; END and complied it with the command line: C:\Documents and Settings\Ed Keith\My Documents\playpen\ocaml>ocamlc -I +camlp4 camlp4lib.cma -pp camlp4orf -c pa_foreach.ml So far so good. Then I ran into the following problem when I tried to use it. Here is the result: C:\Documents and Settings\Ed Keith\My Documents\playpen\ocaml>ocaml Objective Caml version 3.11.0 # #load "camlp4o.cma";; Characters -1--1: #load "camlp4o.cma";; Error: Reference to undefined global `Dynlink' # exit 0;; I have searched the web and I am beginning to suspect that I can not use camlp4 on a windows system, is this the case? If so I can move to a Linux box, but if I can not use it to generate portable code it will not be very useful for me to learn it. -EdK Ed Keith e_d_k@yahoo.com Blog: edkeith.blogspot.com
