[petsc-users] SCALAPACK compilation error

[Satish Balay]

Glad it worked.

Generally we recommend upgrading to latest release of PETSc - as thats
what we primarily support. And some of the issues such as this one
might be fixed in it [so its best not to revisit such issues with
older versions].  If not already fixed - we would look at fixing the
issue in the latest version.

Wrt your specific usage - we recommend using --download-fblaslapack [and
not --download-f2cblaslapack=1] when you have a fortran compiler available
[except when using quad precision build]

It does mean you would have to put some effort updating your code to
use the latest version. We do help with installation issues that you
might encounter. Usually you can grab the 'reconfigure_PETSC_ARCH.py'
script from the previous install and reuse it to build any new
versions.  [yes there can be API changes with configure aswell - so
there could be corner cases with this process]
