I took off the OMPI_IMPORTS actually and it now compiles correctly. Maybe those are to be defined if I had built shared lib version of mpi libs.

thanks

Does this happen also for other MPI_* functions? Probably you need to add OMPI_IMPORTS as an extra preprocessor.

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
