[Boost-users] Selecting among different MPI versions

Hi,

I'm trying to build boost 1.38 with MPI support. The problem is that
my system has more than one version of MPI installed, and the boost
build uses the wrong one. I don't know how boost decides which one to
use. The following are the only default defined by gcc, and none of
them contains mpi.h

g++ -Wp,-v -E -
ignoring nonexistent directory
"/usr/lib/gcc/x86_64-redhat-linux/4.1.1/../../../../x86_64-redhat-linux/include"
#include "..." search starts here:
#include <...> search starts here:
 /usr/local/include
 /usr/lib/gcc/x86_64-redhat-linux/4.1.1/include
 /usr/include
End of search list.

When I try building boost, I get a bunch of messages of the form

...failed gcc.compile.c++
bin.v2/libs/mpi/build/gcc-4.1.1/release/threading-multi/graph_communicator.o...
gcc.compile.c++ bin.v2/libs/mpi/build/gcc-4.1.1/release/threading-multi/group.o
g++: /opt/intel/mpi-rt/3.1: No such file or directory
g++: unrecognized option '-rpath'
In file included from ./boost/mpi/config.hpp:20,
                 from ./boost/mpi/exception.hpp:16,
                 from ./boost/mpi/group.hpp:18,
                 from libs/mpi/src/group.cpp:9:
/usr/local/intel/impi/3.1/include/mpi.h:35:8: error: #error The wrong
version of mpi.h file was included, check include path.

and the version of MPI I want to use is in /usr/local/mpich/...

So is there some option to tell boost which mpi.h to include. I tried
setting the CPLUS_INCLUDE_PATH variable, but it didn't change
anything. I have no control over the OS itself.

Thanks,

a
