[petsc-users] METIS double precision

[Matthew Overholt via petsc-users]

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,
