I’m rather a = win32 user of MPI, so i may be missing some issues.

In your command lin= e, you are rather linking with the lan-mpi library, so it is normal that the mpi version that gets linked is the lan-mpi version.

There should be ano= ther mpi library, rather in the mpich2 install directory.

 

Hope this helps.

Hi there!! Here we go!
Well.. I'm still having some troubles with OcamlMPI.
Mr. Andres Varon, I just tried to compile test.m= l file (i.e.: regression test), which is available on the latest release prov= ided by Mr. Xavier Leroy, by doing what you suggested me to do. Unfortunately, it still didn't work. Thanks anyway, mate!

So, after some time working on that issue, I've eventually got it compiled = by doing the following:

[rodiney@homer ocamlmpi-1.01]$ ocamlc -o testmpi mpi.cma unix.cma test.ml -ccopt -L/usr/lib/lam -ccopt -L/usr/lib/ocaml/ocamlmpi -ccopt -llam -ccopt -lutil

Here is the output:

[rodiney@homer ocamlmpi-1.01]$ ocamlc -o testmpi mpi.cma unix.cma test.ml -ccopt -L/usr/lib/lam -ccopt -L/usr/lib/ocaml/ocamlmpi -ccopt -llam -ccopt -lutil
File "test.ml", line 144, characte= rs 6-9:
Warning Y: unused variable res.
[rodiney@homer ocamlmpi-1.01]$

As you all can see, there is only a warning message. I mean.. no big deal. = So, that command line works pretty good.
The problem occurs when I try to execute 'testmpi' file.
I'm  getting the following message when doing this:

rodiney@homer ocamlmpi-1.01]$ mpirun -np 1 ./testmpi
---------------------------------------------------------------------------= ------------
It seems that there is no lamd running on the host homer.

This indicates that the LAM/MPI runtime environment is not operating.

Please run the "lamboot" command the start the LAM/MPI runtime
environment.  See the LAM/MPI documentation for how to invoke
"lamboot" across multiple machines.
---------------------------------------------------------------------------= ------------

The same message appears by doing 'mpiexec -n 1 ./testmpi' as well.

I would like to remember you, guys, that I'm using MPICH2 implementation of= MPI (mpich2-1.0.6).
So, although MPICH2 is already installed and configured properly, the messa= ge displayed above is just asking to start 'lamboot'. However, 'lamboot' is a = tool provided by LAM/MPI: yet another an MPI implementation. Why it is asking me= for 'lamboot' if I'm using the 'mpd' daemon (i.e.: the process manager) from MPICH2??

Hmm. OK.. I've just started 'lamboot' and I did 'mpiexec -n 1 ./testmp' (or 'mpirun -np 1 ./testmpi') once more. Below is the output:

[rodiney@homer ocamlmpi-1.01]$ mpiexec -n 1 ./testmpi
