geneweb and ocaml 3.07 : help.. :-)

[Christian Perrier <bubulle@debian.org>]

Well, as some of you may know, I'm not an ocaml expert...I'm even not
a coding expert, by the way.

I maintain the geneweb package because it's part of my hobby,
mostly. Also because I think I can make good work with it as long as
it does not invlove digging in the dirt^W code.

So I'm needing some Ocaml competences for helping me.

With ocaml 3.07 release, the geneweb package does not compile from
sources anymore.

This is probably trivial, but I cannot handle this by myself.

Here are the symptoms :

camlp4r pa_ifdef.cmo -DUNIX -o wserver.ppi wserver.mli
ocamlc.opt -warn-error A  -I `camlp4 -where` -c -intf wserver.ppi
File "wserver.mli", line 24, characters 15-46:
The type constructor format expects 3 argument(s),
but is here applied to 4 argument(s)
make[2]: *** [wserver.cmi] Erreur 2

And the offending code :

ifdef OCAML_307 then
value wprint : format 'a out_channel unit unit -> 'a
else
value wprint : format 'a out_channel unit -> 'a;
    (* To be called to print page contents. *)
 
(you will notice the possible OCAML_307 define)

I tried to compile with -DOCAML_307 but the same happens. Probably
because the define is implicit when camlp4r is the 3.07 version.

The only way to get through this is by commenting stuff :

(* ifdef OCAML_307 then
value wprint : format 'a out_channel unit unit -> 'a
else *)
value wprint : format 'a out_channel unit -> 'a;
    (* To be called to print page contents. *)
 

But this is probably silly.. :-)

I could ask Daniel de Rauglaudre, upstream author, but I prefer asking
here first as Daniel is currently very busy and I'd prefer trying this
as a last option....

I would probably need an ocaml expert as co-maintainer for
geneweb... :-)
