Sorry if this turns out to be a dup, but I think my original message got bounced by the list bouncer. On Oct 22, 2007 10:10 AM, Douglas Gregor <dgregor@osl.iu.edu> wrote:
How about putting a
#define MPICH_IGNORE_CXX_SEEK 1
at the top of boost/mpi/config.hpp, before the inclusion of mpi.h?
If that works for you, I'll go ahead and make the change in Subversion. I'd normally just test this myself, but I don't have easy access to an MPICH2 installation at the moment.
IAydin's suggestion to add that flag to the global <cxxflags> fixes the problems, but that's not necessarily the solution to hang your hat on - it should work out of the box (albeit the user may have to add the path to his mpicxx wrapper anyway). I tried your suggestion, but it didn't work. I tracked down the problem to three files that are including mpi.h directly, but not including boost/mpi/config.hpp: ./boost/mpi/detail/packed_oprimitive.hpp ./boost/mpi/detail/packed_iprimitive.hpp ./boost/mpi/detail/mpi_datatype_primitive.hpp I've submitted two patches tha define MPICH_IGNORE_CXX_SEEK in those three files and in boost/mpi/config.hpp. Ticket #1486, here: http://svn.boost.org/trac/boost/ticket/1486 -- Benjamin A.
