Using the cpi VS.NET project distributed with MPICH2 source, there is an attempt to link with mpid.lib. That file is nowhere on our system, after installing the source and the WIN binary distributions. At issue with mpi.lib is that we want to build a debug version of our code. We started with the sample cpi project as a means of seeing a correct build, going from source to cluster runs. Is it necessary to go through the MPICH2 build process to get mpid.lib created? Thank you for any insights you can offer.
