Hi, here is the output of those commands, modified to reflect the actual tool I told boost to use, which is mpiCC, not mpicxx. What should I do with this output, and why does boost not accept it? Thanks! rcook@rzgpu2 (~ ): /usr/local/tools/openmpi-intel-debug-1.8.4/bin/mpicxx --showme:compile -I/usr/local/tools/openmpi-intel-debug-1.8.4/include/openmpi/opal/mca/hwloc/hwloc191/hwloc/include -I/usr/local/tools/openmpi-intel-debug-1.8.4/include/openmpi/opal/mca/event/libevent2021/libevent -I/usr/local/tools/openmpi-intel-debug-1.8.4/include/openmpi/opal/mca/event/libevent2021/libevent/include -I/usr/local/tools/openmpi-intel-debug-1.8.4/include -I/usr/local/tools/openmpi-intel-debug-1.8.4/include/openmpi -pthread rcook@rzgpu2 (~ ): /usr/local/tools/openmpi-intel-debug-1.8.4/bin/mpicxx --showme:link -pthread -Wl,-rpath -Wl,/usr/local/tools/openmpi-intel-debug-1.8.4/lib -Wl,--enable-new-dtags -L/usr/local/tools/openmpi-intel-debug-1.8.4/lib -lmpi Subject: Re: [Boost-users] Cannot build boost with MPI using Intel openMPI wrapper From: Alain Miniussi (alain.miniussi_at_[hidden]) Date: 2015-06-10 10:07:41 * Next message: Hadidi, Lars: "[Boost-users] Boost Random Numbers: Normal Distribution"http://lists.boost.org/boost-users/2015/06/84409.php * Previous message: Boris Schäling: "Re: [Boost-users] Cannot build boost with MPI using Intel openMPI wrapper"http://lists.boost.org/boost-users/2015/06/84407.php * In reply to: Boris Schäling: "Re: [Boost-users] Cannot build boost with MPI using Intel openMPI wrapper"http://lists.boost.org/boost-users/2015/06/84407.php ________________________________ What is the result of: $/usr/local/tools/openmpi-intel-debug-1.8.4/bin/mpicxx --showme:compile $/usr/local/tools/openmpi-intel-debug-1.8.4/bin/mpicxx --showme:link ?

Hello, I'm seeing this in my build output. I'm hoping someone can help me find out what the actual problem is. Thanks for any assistance.

===============MPI Auto-configuration=============== MPI auto-detection failed: unknown wrapper compiler /usr/local/tools/openmpi-intel-debug-1.8.4/bin/mpiCC Please report this error to the Boost mailing list: http://www.boost.orghttp://www.boost.org/ You will need to manually configure MPI support. MPI launcher: mpirun -np ====================================================

Here are the commands that generated it:

+ mkdir -p //usr/local/tools/boost-intel-1.57.0 + mkdir -p //usr/local/bin + pushd boost_1_57_0 /tmp/dpkg-mkdeb.1Tdcc4kqMi/src/boost_1_57_0 /tmp/dpkg-mkdeb.1Tdcc4kqMi/src + ./bootstrap.sh --prefix=/usr/local/tools/boost-intel-1.57.0 + echo 'using mpi : /usr/local/tools/openmpi-intel-debug-1.8.4/bin/mpiCC ;' >> tools/build/src/user-config.jam

+ ./b2 -j20 --debug-configuration install

It's a while ago that I was using Boost.MPI. But if auto-detection fails, you could pass MPI-related options explicitly. There is this remark in the MPI Jamfile:

# If your MPI implementation does not have a wrapper compiler, or the MPI # auto-detection code does not work with your MPI's wrapper compiler, # you can pass MPI-related options explicitly via the second parameter to the # mpi module: # # using mpi : : <find-shared-library>lammpio <find-shared-library>lammpi++ # <find-shared-library>mpi <find-shared-library>lam # <find-shared-library>dl ;

HTH, Boris
