Hi Jack,
actually bjam is giving you a hint about what you should add to your
compiler command line:

The following directory should be added to compiler include paths:
/lustre/jxding/boost_2010_6_8/boost_1_43_0
The following directory should be added to linker library paths:
/lustre/jxding/boost_2010_6_8/boost_1_43_0/stage/lib
g++ option "-I" adds a directory to the include path and option "-L" adds a directory to the linker library path; in addition to that, to produce the actual executable file, you'll need to link against the "boost_mpi" and "boost_serialization" libraries: libraries are specified using the compiler's "-l" option. So, I'd guess that you need to invoke the mpic++ compiler this way:: mpic++ -o testp2p test_p2p.cpp \ -I/lustre/jxding/boost_2010_6_8/boost_1_43_0 \ -L/lustre/jxding/boost_2010_6_8/boost_1_43_0/stage/lib \ -lboost_mpi -lboost_serialization
It seems that I need to specify I need to use mpi for the bjam builder.
But, I have added "using mpi ;" and "using mpi : /opt/openmpi-gnu/bin/mpic++ ;" in the file /home/myname/boost_2010_6_8/boost_1_43_0/user-config.jam.
I have also added it in the file /home/myname/boost_2010_6_8/boost_1_43_0/tools/build/v2/user-config.jam.
But, I still got the same error. It seems that there is something wrong with the package ? or the compiler cannot understand the "using mpi ;" in the user-config.jam ?
I had to add the "using mpi ;" line to the file "project-config.jam"; creating a "user-config.jam" did not work for me (but I didn't really look into the issue, so likely I did something wrong). Anyway, there is a simple check to see if the Boost.MPI library has been built: search for a file named "libboost_mpi.a" into /lustre/jxding/boost_2010_6_8/boost_1_43_0/stage/lib (or whatever directory "bjam" suggests that you add to the linker library path). If the file is there, MPI support has been built. Best regards, Riccardo -- Riccardo Murri, Hadlaubstr. 150, 8006 Zürich (CH)
