[mpich-discuss] Hi

Hi,
 The linker error indicates that you have not specified the MPICH2
libraries as "Additional dependencies" for the linker.
 Specify the path of MPICH2 libraries (the default path is "c:\program
files\mpich2\lib") in "Additional library directories" (Project properties
--> Configuration properties --> Linker --> Additional library
directories). Specify the MPICH2 libraries (mpi.lib) as "Additional
dependencies" (Project properties --> Configuration properties --> Linker
--> Input --> Additional dependencies).
 You can find this information in the windows developer's guide (available
at
http://www.mcs.anl.gov/research/projects/mpich2/documentation/index.php?s=
docs). You can also refer to the example project files installed with
MPICH2 (examples\examples.sln).
 Let us know if you still have problems.
 
Regards,
Jayesh
