So... I just committed the initial round of changes to allow attaching a
Preconditioner object to either a linear or nonlinear solver and it
works!
I'm already using this in my code with a special preconditioner object to do
fairly complicated solver library (petsc/trilinos) agnostic preconditi

I just committed a configure test for Hypre that will def

Does PETSc end up including any HYPRE headers from the PETSc headers?
If so then #ifdef
So it looks like we only snoop petscconf in our Makefile(.in). Should
I just snoop for HYPRE_LIB there and add a -DPETSC_HAS_HYPRE to our
compile line? Or should I go snoop petscconf manually during
configure so a #define can get set in libmesh_configure.h?

Thanks John... I'll work up a configure test for this.

Looks like HYPRE_INCLUDE and HYPRE_LIB will be set in
$PETSC_DIR/bmake/${PE
Does anyone know how to snoop to see if Petsc is configured with Hypre
support? I don't see a simple #define HAS_HYPRE or some such anywhere
in the Petsc source.
Thanks,

I'll take care of this immediately... thanks for pointing it out. I
looked at the code and thought that that function would be present
regardless of whether or not you configured Petsc with Hypre... guess
I was wrong.
Thanks!

Dear Derek/Roy,
Just to briefly join in the preconditioner discussion: Have you also
thought about something like a ShellPreconditioner class (analogously
to the ShellMatrix)? It's not that I would need it now, but someone
(perhaps me) might need it in the future, and it would certainly be

Unfortunately, it doesn't link for me. I get:

Ok - I went ahead and committed that so that I can work on the next
step... which is allowing you to attach a Preconditioner to the linear
solver. But now we need some discussion on that.
First, do we want to support the old style of specifying a
preconditioner type for a LinearSolver? Or

So... I've got the initial Preconditioner class and a PetscPreconditioner
