I guess you are right.. I have some problems with some basic boost mpi
stuffs itself..

I ran a simple program using boost mpi but I found some problems with that.
I have given the code and actions I have done. The ldd clearly says it cant
find many libraries. I am not sure how to fix this. Could you please help me
?

main.cpp

#include <boost/mpi/environment.hpp>#include
<boost/mpi/communicator.hpp>#include <iostream>namespace mpi =
boost::mpi;
int main(int argc, char* argv[]) {
  mpi::environment env(argc, argv);
  mpi::communicator world;
  std::cout << "I am process " << world.rank() << " of " << world.size()
            << "." << std::endl;
  return 0;}

[pragatheeswaran_at_prairiefire ~]$ mpic++ -I bin/boostpath/include main.cpp -L
