problem in running c++ program on Boost.MPI

[Vineet Pratap (Vampaier)]

hi,

 i write simple hello.cpp program that is

#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;
}

my problem is "when i compile this using
mpicxx -I /home/vineet/boost_1_40_0/ hello.cpp -o h.out -L /home/vineet/boost_1_40_0/stage/lib/*
it compile successfully but when run by using:

 mpirun -np 4 ./h.out
./h.out: error while loading shared libraries: libboost_mpi.so.1.40.0: cannot open shared object file: No such file or directory
./h.out: error while loading shared libraries: libboost_mpi.so.1.40.0: cannot open shared object file: No such file or directory
./h.out: error while loading shared libraries: libboost_mpi.so.1.40.0: cannot open shared object file: No such file or directory
./h.out: error while loading shared libraries: libboost_mpi.so.1.40.0: cannot open shared object file: No such file or directory

note: mpich2 is bulid successful

Try adding the location of the libraries to LD_LIBRARY_PATH
