[MPI] compilation error with msvc 64bit due to size_t datatype
Hello, I cannot compile boost.mpi with msvc 8.0 64bit. The complete error message is attached. The reason is that is_mpi_datatype<std::size_t> derives from mpl::true_ with the 32 bit compiler while it derives from mpl::false_ with the 64bit compiler. Unfortunately, I do not understand the reason, so I cannot fix it. I would be grad if someone could help. best regards, Andreas Buhr -- Ist Ihr Browser Vista-kompatibel?

The problem here is that Boost.MPI isn't properly defining the MPI datatype for "std::size_t". Could you try changing the "#if 0" on line 255 of boost/mpi/datatype.hpp to "#if 1"? - Doug

Thanks a lot, that fixed it. I am able to compile boost 1.35 with mpi using MSVC 2005 64bit if "long long" and "unsigned long long" are defined as MPI datatype, the definition enabled by the procedure you described. Andreas

Great! The Boost trunk and release branches have a more correct version of this fix, along with another datatype-related fix that solved some problems I ran into with MSVC 2008. - Doug
