Hi thanks
Although I added the link for the library, I still got the same error:----------------------------------------------------------------------------- mpic++ -o tp2p test_p2p.cpp  -I/home/mypath/boost_2010_6_8/boost_1_43_0test_p2p.cpp:6:38: error: /boost/mpi/environment.hpp: No such file or directorytest_p2p.cpp: In function âint main(int, char**)â:test_p2p.cpp:18: error: âenvironmentâ is not a member of âmpiâtest_p2p.cpp:18: error: expected `;' before âenvâ------------------------------------------------------------------------------
According to the instruction of boost.mpi:
http://www.boost.org/doc/libs/1_43_0/doc/html/mpi/getting_started.html#mpi.testing
I also tried :mpic++ -I/path/to/boost/mpi my_application.cpp -Llibdir  -lboost_mpi-gcc-mt-1_35 -lboost_serialization-gcc-d-1_35.a
But also errors: ----------------------------------------------------------------------------------------------------- mpic++ -I/home/mypath/boost_2010_6_8/boost_1_43_0/boost/mpi -o tp2p test_p2p.cpp -Llibdir   -lboost_mpi-gcc-mt-1_35 -lboost_serialization-gcc-d-1_35.atest_p2p.cpp:6:38: error: /boost/mpi/environment.hpp: No such file or directorytest_p2p.cpp:11:38: error: boost/mpi/communicator.hpp: No such file or directorytest_p2p.cpp:14: error: âboostâ has not been declaredtest_p2p.cpp:14: error: âmpiâ is not a namespace-nametest_p2p.cpp:14: error: expected namespace-name before â;â tokentest_p2p.cpp: In function âint main(int, char**)â:test_p2p.cpp:18: error: âmpiâ has not been declaredtest_p2p.cpp:18: error: expected `;' before âenvâtest_p2p.cpp:19: error: âmpiâ has not been declaredtest_p2p.cpp:19: error: expected `;' before âworldâtest_p2p.cpp:20: error: âworldâ was not declared in this scope-----------------------------------------------------------------------------------------------------------
I have built and installed mpi libraries.
Why ? 
Any help is appreciated. 

thanks
Jack
