I believe he's not referring to simultaneous use of pa_monad and another extension in user code, but of Camlp4MacroParser *in* the sources of pa_monad. Since pa_monad is build with ocamlc -I +camlp4 -pp camlp4orf -c pa_monad.ml changing that to ocamlc -I +camlp4 -pp "camlp4orf Camlp4MacroParser.cmo" -c pa_monad.ml might work. -- Mauricio Fernandez - http://eigenclass.org _______________________________________________ Caml-list mailing list.
