Thanks for your reply. 
I added it, but the same error. 
I found the possible reason is that the compiler cannot find the header files in the program. 
This is my program got from the boost download package. --------------------------------------------------------------------------------#include </home/mypath/boost_2010_6_8/boost_1_43_0/boost/mpi/environment.hpp>
#include </home/mypath/boost_2010_6_8/boost_1_43_0/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;}-----------------------------------------------------------------------------------
The g++ compiler can find  "environment.hpp" because I have indicated the absolute path. But, inside the "environment.hpp", it needs other header files such as " boost/mpi/config.hpp". 
I have installed the boost lib in mypath with the prefix=mypath. 
I have also update the PATH and LD_LIBRARY_PATH variable name with the boost path in my shell. 
Why does the compiler not find them ?
Any help is appreciated. 
thanks,
Jack
