Thanks !

So far, I've been able to recompile noweb and findlib. However, I have
a problem with ocaml-equeue, which doesn't compile:

ocamlfind ocamlopt  -package "" -c -thread unixqueue_mt.ml
ocamlfind: ocamlopt does not support multi-threaded programs for your
configuration

After some search, I found that the ocaml available in Mandriva was
compiled without -with-pthread. So I recompiled the ocaml package with
this option, but I still get the same error.

I've looked inside findlib code, but I don't really understand what's
going on. It seems that there are two types of threads: Posix Threads
(on Ocaml thread mapped to one Posix thread), and VM Threads (threads
simulated by Ocaml). The following source code:

  ( match !threads with
        `None ->
          ()

      | `VM_threads ->
          if which = "ocamlopt" then
            failwith "ocamlopt does not support multi-threaded programs
for your configuration"; pass_options := !pass_options @
[ "-vmthread" ]; predicates := "mt" :: "mt_vm" :: !predicates;

      | `POSIX_threads ->
          pass_options := !pass_options @ [ "-thread" ];
          predicates := "mt" :: "mt_posix" :: !predicates;

seems to indicate that VM_Threads are not possible with ocamlopt.
However, I compiled ocaml with POSIX_threads, so it should work,
doesn't it ? Am I missing something ? How can I check that my Ocaml
compiler was really compiled with -with-pthread ?

Thanks !

Thomas
