Hi,

I have a problem for compiling boost with MPI. I use the last version of MPICH2, unfortunately with a bug in mpicxx.h . So I used these commands lines :

- b2 toolset=gcc --j4 --layout=system release --prefix=C:\librairies\boost-1.53.0 --user-config=user-config.jam cxxflags=- DMPICH_SKIP_MPICXX install

- b2 toolset=gcc --j4 --layout=system release --prefix=C:\librairies\boost-1.53.0 --user-config=user-config.jam define=MPICH_SKIP_MPICXX install

and always the same error :

gcc.link.dll bin.v2\libs\mpi\build\gcc-mingw-4.7.2\release\threading-multi\libmpi.dll.a

And I think the flag "MPICH_SKIP_MPICXX" override some others defined in libs/mpi/build/Jamfile.v2. Anyone know how to add this flag without overriding the existing ones ?

Thanks in advance.
