Compilation problem when using openmpi-1.3.3

[Kui Gao]

Hi Chris,
	The attached patch is for openmpi-1.3.3. The patch should apply to
the original parallel-netcdf1.1.0. A new MPI_Datatype variable is added in
the struct in order to avoid the convert between nc_type and MPI_Datatype.
	
	Thanks a lot for Rich's patch.

Kui.

I found that the attached patch I created helped me in compiling
parallel-netcdf 1.1.0 with openmpi (version 1.2.7). Note that the patch
should apply to the original parallel-netcdf 1.1.0 distribution. It
contained addition fix (for C++ compiler) I reported early.

Best regards,

Hi Kui,

I applied the patch, and now get a different compilation error:

Hi Chris,
       Thank you very much for your report. It is a bug.        "nc_type
vartype" should be replaced by "MPI_Datatype vartype" at
L66 in src/lib/pnetcdf.h .        The patch file is attached.
       Thanks,

Kui.

Yeah you're right that does look like a bug. Thanks! -- Rob

Hi all,


I'm unable to compile parallel-netcdf-1.1.0 with openmpi-1.3.3  compiler
wrapper script (using gcc 4.4.2). I get the following compilation  error:


mpinetcdf.c:13216: error: incompatible types when assigning to type
'nc_type' from type 'MPI_Datatype'

(*request)->vartype = datatype;


This looks like a bug to me as vartype is an enum field in the
NCMPI_Req data structure.


I am able to compile parallel-netcdf-1.1.0 with mpich2-1.1.1p1
compiler wrapper script. I think this is because MPI_Datatype is
a typedef for an integer in mpich, and so can be freely
mixed with enum types. This is not the case in openmpi where
MPI_Datatype is a typedef for a pointer to struct.


Thanks for any help,
Chris
