Hi,

I am trying to get boost::mpi working on windows system so I have download 1_35_0 version and compile it for msvc 7.1.

When I tried to compile sample code
#include <boost/mpi.hpp>
#include <iostream>
#include <boost/serialization/string.hpp>

namespace mpi = boost::mpi;

int main(int argc, char* argv[])
{
mpi::environment env(argc, argv);
mpi::communicator world;

if (world.rank() == 0) {
    world.send(1, 0, std::string("Hello"));
    std::string msg;
    world.recv(1, 1, msg);
    std::cout << "I am Process #" << world.rank() << " This is message from 1" << msg << "!" << std::endl;
} else {
    std::string msg;
    world.recv(0, 0, msg);
    std::cout << "I am Process #" << world.rank() << " This is message from 0"<< msg << ", ";
    std::cout.flush();
    world.send(0, 1, std::string("world"));
}
/*

std::string value;
if (world.rank() == 0) {
    value = "Hello, World!";
}

broadcast(world, value, 0);

std::cout << "I am Process #" << world.rank() << " of " << world.size() << " says " << value
            << std::endl;
*/
return 0;
}
