[MPICH2-dev] Error creating custom MPI Type struct

[Shankar, Shashank (US - New York)]

Hello Rajeev,

Yes, I am building the application on Windows (Server 2003, in case that
makes a difference).

I checked the mpi.h file for the mentioned #define's and they are
exactly the same as those you provided.

Thanks!

This code runs on Linux without any problem. You are running on Windows
I
believe. I don't know about the Windows version. In the mpi.h file, just
check wether the #defines for the datatypes appear meaningful (not 0 for
example). In my Linux build, it looks something like:

#define MPI_CHAR           ((MPI_Datatype)0x4c000101)
#define MPI_SIGNED_CHAR    ((MPI_Datatype)0x4c000118)
#define MPI_UNSIGNED_CHAR  ((MPI_Datatype)0x4c000102)
#define MPI_BYTE           ((MPI_Datatype)0x4c00010d)
#define MPI_WCHAR          ((MPI_Datatype)0x4c00040e)
#define MPI_SHORT          ((MPI_Datatype)0x4c000203)
#define MPI_UNSIGNED_SHORT ((MPI_Datatype)0x4c000204)
#define MPI_INT            ((MPI_Datatype)0x4c000405)
#define MPI_UNSIGNED       ((MPI_Datatype)0x4c000406)
#define MPI_LONG           ((MPI_Datatype)0x4c000407)
#define MPI_UNSIGNED_LONG  ((MPI_Datatype)0x4c000408)
#define MPI_FLOAT          ((MPI_Datatype)0x4c00040a)
#define MPI_DOUBLE         ((MPI_Datatype)0x4c00080b)
#define MPI_LONG_DOUBLE    ((MPI_Datatype)0x4c000c0c)
#define MPI_LONG_LONG_INT  ((MPI_Datatype)0x4c000809)
#define MPI_UNSIGNED_LONG_LONG ((MPI_Datatype)0x4c000819)
#define MPI_LONG_LONG      MPI_LONG_LONG_INT

#define MPI_PACKED         ((MPI_Datatype)0x4c00010f)
#define MPI_LB             ((MPI_Datatype)0x4c000010)
#define MPI_UB             ((MPI_Datatype)0x4c000011)
