[MPICH] LoadLibrary("mpich2d.dll") fails, how can I link statically on Windows?

[David Ashton]

Robin Boerdijk,

Yes, I forgot about those changes.  We moved the MPI_F_STATUS(ES)_IGNORE
variables from the Fortran library to the C library.  Comment out the lines
in mpi.c that reference them.  If you plan on using those variables, you
will have to wait for the next release.

Hi David,

I recompiled MPICH2 with the latest mpi.c, but now my MPI program fails
to start with the following message displayed by Windows: "First-chance
exception at 0x1002885f (mpich2mpid.dll) in MyMPIProgram.exe:
0xC0000005: Access violation writing location 0x00000000.".

When I run my MPI program in the debugger it breaks at the following
line in mpi.c:

int MPI_Init( int *argc, char ***argv )
{
    int result;
    MPICH_CHECK_INIT(FCNAME);
    result = fn.MPI_Init(argc, argv);
    *fn.MPI_F_STATUS_IGNORE = MPI_F_STATUS_IGNORE; // <- crash
    *fn.MPI_F_STATUSES_IGNORE = MPI_F_STATUSES_IGNORE;
    return result;
}

Apparently, the 

    fn.MPI_F_STATUS_IGNORE = (MPI_Fint**)GetProcAddress(hPMPIModule,
"MPI_F_STATUS_IGNORE");

statement in LoadFunctions() has set fn.MPI_F_STATUS_IGNORE to NULL. 

Do I need to update some more files to make it work?

Best regards,

Robin Boerdijk
