Hi,
I get this style of errors when trying to link against libmpid.lib (compiled with instructions from README.Windows part 1 cmake): mylib.lib(myfile.obj): : error LNK2001: unresolved external symbol __imp__MPI_Address I set BUILD_SHARED_LIBS to false, so I generate static libs. I've also checked that the /MDd is set and indeed libmpid.lib are built against the DLL version of the C++ runtime when I open the solution in vs2010. I myself link my application against the /MDd as well. I don't know why it's looking for __impl__MPI_Address (__impl__ is a prefix related to DLLs somehow). I gather this MPI_Address() function resides in libmpi.lib and libmpid.lib PS: I didn't have these link errors when I built against the prebuilt win libraries from the website, what are the CMAke flags for those? Thanks, MM
