[mpich-discuss] LNK2019 error on Windows 7 and Visual Studio 2008 using MPI

[Jayesh Krishna]

Hi,
 Good to know MPICH2 worked for you. However if your system is x64 I would recommend installing the x64 version of MPICH2 and building a x64 executable (In VS you might have to change the build configuration. Google for building 64-bit apps using VS.).

Regards,
Jayesh

I uninstalled the 64-bit version and installed the 32-bit version of 
MPICH2 and now my code compiles in Visual Studio. It does this with just 
the mpi.lib without the cxx.lib file in the Additional Dependencies box. 
Thanks for the help.
