[petsc-users] METIS double precision

Hello,
How does one configure the PETSc installation to download METIS and have it
use REALTYPEWIDTH 64 (as defined in metis.h)? I am using:
--with-64-bit-indices --download-metis=yes
to get IDXTYPEWIDTH 64. If I were installing METIS independently I would
set the following near the top of metis.h: #define
METIS_USE_DOUBLEPRECISION
The reason for this is I want to call METIS routines outside of PETSc and
prefer double precision.
Thanks,
Matt Overholt
