Ok, so I've been trying to get boost::mpi and OpenMPI to play nicely together on Windows using Visual Studio 2013. Anyway, I've managed to build boost::mpi via manually specifying the path in mpi.jam as advised to at How to build boost::mpi library with Open MPI on Windows with Visual Studio 2010
So far so good.
I add the resulting lib files into my library path (libboost_mpi-vc120-mt-1_55.lib etc.) and proceed to build my application. These lib files are detected and linked in correctly, however there are link errors originating from the boost mpi lib file. So, I add all OpenMPI x64 libraries into my linker and get the same result. Naturally, I'm confused.
One of the link errors boost gives me is:
libboost_mpi-vc120-mt-1_55.lib(request.obj) : error LNK2001: unresolved external symbol ompi_request_null
So, dumpbin to the rescue...
$dumpbin.exe -headers libmpi.lib > mpi.out
Version : 0
Machine : 8664 (x64)

DLL name : libmpi.dll
Symbol name : ompi_request_null
Type : data
Name type : name
Hint : 1187
Name : ompi_request_null
As you can see, libmpi.lib contains the symbol that the boost library can't find, and the library is indeed x64 (as is boost).
I know on unix the link order is important, so I tried manually linking libboost_mpi-vc120-mt-1_55.lib before libmpi.lib, but that didn't change anything.
I'm out of ideas. I don't usually like posting about link errors, but this one seems to have me beat..
