[mpich-discuss] Fatal error in MPI_Init

Wed Aug 5 16:38:35 CDT 2009

Hi,

I could make the program work, but there are some points I still would like
to clarify.

The problem is that my program also links to another library using its dll
file. However, in my development environment, these dll's are not placed in
the same directory where I build my application. Actually, I keep these
dll's in the library's installation directory and my PATH environment
variable points to this folder.

I could just figure out of the problem because I was trying to reduce my
applications size and, in order to do that, I replaced many of the
subroutines by dummy ones. When I disabled my part of the code related to
the second library, it worked.

So, the solution I found was to copy the needed dll's to my application's
folder. But I'm not so comfortable with this because this scheme had always
worked, even with MPICH1 (i.e., when I link and run my application with
MPIRUN).

Is such behavior expected? Why does mpiexec work differently from mpirun?
Any mistake from my side?

Another point is that I use to include 'mpif.h' in my Fortran routines that
use MPICH2 and, I link my application with mpich2.lib and fmpich2.lib, which
are the import libraries I have created from mpich2.dll and fmpich2.dll,
using OpenWatcom "wlib" utility.

I didn't know that the correct library to use was mpich2mpi.dll. Sorry for
the question, but what are the differences?
As I could make it run with mpich2.dll and fmpich2.dll, what kind of errors
may I expect?

Thanks again.
