Hello,

I'm trying to compile Boost.MPI on a Cray XK6 machine. The MPI wrapper compiler is called `CC` and should be invoked with no particular options. However, Boost complains that `CC` is not known and does not compile Boost.MPI:

MPI auto-detection failed: unknown wrapper compiler CC Please report this error to the Boost mailing list: http://www.boost.org You will need to manually configure MPI support. warning: skipping optional Message Passing Interface (MPI) library. note: to enable MPI support, add "using mpi ;" to user-config.jam. note: to suppress this message, pass "--without-mpi" to bjam. note: otherwise, you can safely ignore this message.

I have added the following to the top-level `project-config.jam` file, but it does not help Jam to DTRT:

using mpi : CC ;

Any hints on how to proceed?

Thanks, Riccardo

The actual line is more like (assuming your are compiling with gcc): using mpi : /opt/cray/xt-asyncpe/default/bin/CC : <include>/opt/cray/mpt/default/gni/mpich2-gnu/include <library-path>/opt/cray/mpt/default/gni/mpich2-gnu/lib <find-shared-library>mpichcxx <find-shared-library>mpich ; Note that your include/library-path directories might be different if depending if you are compiling with gcc/icc/cray/pgi etc Also, you might have to also choose some sub-directory under /opt/cray/mpt/default/gni/mpich2-gnu (some machines have multiple versions)
