[mvapich-discuss] Building Panasis support for MVAPICH2, possible issue with included files

[David Gunter]

I believe I have found a bug in the mvapich2 build process when  
enabling Panasas file system support.

I followed the advice in the README.romio file but I was getting an  
error associated with being unable to find mpi.h.

Along with my other configure options, I've included the "--enable- 
romio --with-file-system=panfs+ufs+nfs" part.  I have also made sure  
that CFLAGS contains a "-I/usr/include" since the panasas header  
files are located there.  The build follows the configure set up as  
normal until it gets to building the panfs bit:

...

It appears that mvapich2-0.9.8/src/mpi/romio/adio/include/adio.h  
requires mpi.h, but there is no mpi.h to be found.  I changed a line in
mvapich2-0.9.8/src/mpi/romio/adio/ad_panfs/Makefile.in to point back  
to mvapich2-0.9.8/src/include and it then completes without error.

Here is the change I made:

From:
  INCLUDE_DIR = -I at MPI_INCLUDE_DIR@ -I${srcdir}/../include -I../ 
include -I../../include -I/opt/panfs/include

To:
INCLUDE_DIR = -I at MPI_INCLUDE_DIR@ -I${srcdir}/../include -I../include  
-I../../include -I../../../../include -I/opt/panfs
/include

Thanks,
