Hi all, I need some help with building Boost.MPI. My system is a Debian testing (lenny) system and I'm following the instructions at [lenny uses 1.35 and not 1.36]: http://www.boost.org/doc/libs/1_35_0/doc/html/mpi/getting_started.html I'm using Open MPI and I can compile and run the test implementation fine (mpi-test.cpp). So, I moved to the next step on configuring and building. My bjam is 3.1.16. I copied user-config.jam to my home directory, with the line "using mpi ;" added at the end. Then, I ran "bjam --with-mpi" in the "top-level Boost directory" [*] and I get this error: error: no Jamfile in current directory found, and no target references specified. Firstly, I'm not sure if I have everything installed... But I also don't know what the "top-level Boost directory" is. I've tried these locations: /usr/share/boost-build/ /usr/share/boost-build/build/ /usr/share/boost-build/tools/ [it had an mpi.jam file in it] /usr/include/boost/ And also replaced "using mpi ;" with "using mpi : /usr/bin/mpic++ ;". I'm currently trying this as root user, so I don't think root privileges is the problem. (bjam came with a "Hello World" example and that compiled fine; so I don't think it's something wrong with bjam.) Any help would be appreciated... Thanks! Ray
