compiling error when using mpich2

Message

Our cluster seems to be unstable w.r.t to mpich1 so we are migrating to mpich2. This requires recompilation of vasp. I am compiling vasp on a test machine which is an intel xeon with dual core processor. When I try to compile vasp4.6.28, I get the following error:

IPO Error: unresolved : mpi_conversion_fn_null_
Referenced in mpi.o

and the installation crashes.

I am using the mpif90 compiler which was compiled using ifort.

Is this an error in vasp or mpich2 ?? Can someone please help

Thanks

this error is not vasp-related

Thanks, Has anyone ever tried to compile vasp using mpich2 coz I have no idea how to even start looking for the cause of this error.

I had exactly the same issue:
IPO Error: unresolved : mpi_conversion_fn_null_
Referenced in mpi.o

what is the solution?
