Thanks! I'm not able to recompile Open MPI on Win32, so I've downloaded and installed the Windows installer that I've found in http://www.open-mpi.org/software/ompi/v1.5; then I've configured the user-config.jam adding the line:
using mpi ;
So I've tried to build the boost with this command:
bjam debug release -a --toolset=msvc-10.0 stage
but it can't able to find the MPI install. The compiler message is:
MPI auto-detection failed: unknown wrapper compiler C:/Programmi/OpenMPI_v1.5.2-win32/bin/mpic++.exe Please report this error to the Boost mailing list: http://www.boost.org You will need to manually configure MPI support.
So I've tried to modify the user-config.jam in:
using mpi : C:/Programmi/OpenMPI_v1.5.2-win32/bin/mpic++.exe ;
But the error is the same.
The Boost.MPI getting started page also metions these steps:
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 ;
To see the results of MPI auto-detection, pass --debug-configuration on the bjam command line.
Did you try those? -Julian
