Re: [Boost-users] boost.MPI test error

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 #include #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 June 9 2010

my compile command: g++ -o testp2p test_p2p.cpp I got error : /boost/mpi/environment.hpp:16:32: error: boost/mpi/config.hpp: No such file or directory

quite likely you have to add "-I./" to the compiler command line::

g++ -o testp2p -I./ test_p2p.cpp
