Hi,

I want to used OCaml for parallel computing. For this, I used the Paderborn
University BSP-Library (http://wwwcs.upb.de/~bsp/), i.e, a C-compiler for
parallel computing (like mpicc) and I write a library in the spirit of
ocamlMPI of Xavier Leroy (i.e, a "C file" using <mpi.h> calling the mpi
primitives and a camlmpi.ml file for Interfacing mpi with Objective Caml)

When I compile the library (using ocamlopt), I have no problem. But when I
want an executable:

ocamlopt -thread unix.cmxa threads.cmxa -I /home/gava/lib/
/home/gava/lib/libbsmllib.pub_stubs.a files.cmx files.cmxa
parallel_caml.pub.cmxa  -cc pubcc -o prog prog.ml

where files.cmx(a) are other libraries (tools) in the directory
(/home/gava/lib/). I have this error message:

/usr/local/pub/lib/pc/linux/tcpip/libpub_d.a(system_unix.o): In function

Anybody have an idea ?
Thanks.
