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.
