Please do a fresh version of the --download-parmetis run and send the
configure.log to petsc-maint at mcs.anl.gov This mailing list is not for large
attachments or configure failures.
To make sure everything is clean please remove

Dear developers,
I have compiled petsc-3.1-p8 for a while. Now I would like to use
superlu as an ilu preconditioner, since it offers the drop tolerance
option. I have read in a thread
(https://lists.mcs.anl.gov/mailman/htdig/petsc-users/2010-December/007439.html)
that one can run the code with
There is a tiny bit of information in the PETSc users manual about Eclipse:
\section{Eclipse Users} \sindex{eclipse}
If you are interested in developing code that uses PETSc from Eclipse or
developing PETSc in Eclipse and have knowledge of how to do indexing and build
libraries in Eclipse pl
Did you call KSPSetFromOptions(ksp)?
Run your code with '-options_table' to dump list of options inputted
or '-options_left' to dump list of unused options.
I tested with petsc-3.1/src/ksp/ksp/examples/tutorials/ex2.c:
./ex2 -pc_type ilu -pc_factor_mat_solver_package superlu
-mat_superlu_ilu_dropt
Does Eclipse use its own proprietary project files vs. makefiles? ---John

Try using Cygwin to build the PETSc libraries with VC++. This way
you'll have the *.lib (vs. *.a Unix/Linux/Cygwin libraries) files you
can link against. Go to the install PETSc instructions and follow the
ones for Win32.

Dear all,
Is there a preprocessor directive to check if PETSc has been compiled with hdf5
or not ? (something like PETSC_HAS_HDF5?!!)
Best,
Ata

We cannot handle winmail.dat attachments.
Seems likely you have ierr declared both in the module and in your routine,
and the compiler cannot handle that. Since you are using ierr as an argument to
your subroutines I don't think you should be declaring it in the module at all.
