Re: [Boost-users] [MPI] compilation error with msvc 64bit due to size_t datatype

I cannot compile boost.mpi with msvc 8.0 64bit. The complete error message is attached.

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"?

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
