Now I see the problem. The Open MPI binaries were build with Microsoft
cl compiler, it has different name conventions, so the symbols couldn't
be resolved by g++ compiler. I've started the native MinGW compiler
support, some projects can already be built via gcc or g++, but it's not
finished yet.

Hi,
Which command did you use to compile your code?
I tried following code on my Windows 7 machine with compile
command "mpicxx hello.cpp":
hello.cpp
===================================
# include "mpi.h"
using namespace std;
int main ( int argc, char *argv[] )
{
int rank, size;
MPI::Init ( argc, argv );
size = MPI::COMM_WORLD.Get_size ( );
rank = MPI::COMM_WORLD.Get_rank ( );
printf("Rank # %d \n", rank);
MPI::Finalize ( );
return 0;
}
console output :

When I tried CMake with GUI for version 1.4.3, no .sln file

Hi,
I've solved the same weird error on Linux, but have not
tried Windows yet. The error recurs on Linux system, when I
firstly use mpich on my Linux, the program works fine, then I
uninstalled it and switched to your open-mpi, the error came
out without warning, and I tried to change the compiler to
mpic++ other than g++, the error remains. So I doubt if the
Boost.MPI is compatible with current MPI system, I recompiled
the Boost.MPI library and substituted the old ones, the code
with Boost library came back to work. So I guess the old
compiled Boost library depends on other library like mpich,
so it can't work with current open-mpi because they are
incompatible, however, I'm still confused why simple code (In
the last mail I sent to you) which does not depend on Boost
library(I never used mpich on Windows before), can not work.
Wishes~

Hi,
The code works for me under MinGW console with the
pre-compiled installer. Could you try "which mpicc" to
ensure that the correct Open MPI commands are in path?
For building Open MPI by your self with CMake, you have
to configure it in the GUI and then generate the sln
files by pressing the generate button. I don't recommend
to use the other two means, they haven't been tested for
some while.

hi,
the following code:
int main(int argc, char **argv)
{
int procnum;
/* Initialize MPI */
MPI_Init(&argc, &argv);
/* Find out this processor number */
MPI_Comm_rank(MPI_COMM_WORLD, &procnum);
/* Find out the number of processors */
std::cout << "I'm process: " << procnum << std::endl;
MPI_Finalize();
return 0;
}
also goes with the same rank "0" error, I think if
there's something wrong with the auxiliary program
"mpirun" ?
BTW, I tried all the 3 means on your
http://svn.open-mpi.org/svn/ompi/trunk/README.WINDOWS.txt guideline
but none worked to compile my own dll for
http://www.open-mpi.org/software/ompi/v1.4/downloads/openmpi-1.4.3.tar.bz2,
the first approach failed because I found no .sln file
in the distributed tarballs after configuring with
cmake, the second mean I can not use is the lacking of
ompi-static.tgz file, the 3rd solution I tried does not
work neither, because I don't know what the ash.exe
shell interpreter you are actually pointing to, so I'd
be much appreciated if you can tell me the a working
approach. Thanks very much.

Hi,
I've never tried this Boost.MPI with Open MPI on
Windows. Does it work without the Boost.MPI library?
Did you run your test under MinGW?

following codes:
int main(int argc, char **argv)

mpi::environment env(argc, argv); // Boost.MPI class
boost::mpi::communicator worldCom; // Boost.MPI class
std::cout << "rank():" << worldCom.rank() << std::endl;

and successfully compiled and linked with your
library as "a.exe" by mingw, however, if I run it:
>mpirun -np 4 a.exe
the command will create 4 process with the same
rank "0", I wonder if it's the bug of your unstable
release for windows?
BTW, can you publish the Visual studio project to
the subversion? Thanks very much.
