Re: [Libmesh-users] AW: Petsc/Slepc 2.3.1 and BLOPEX support

Steffen,

I'm working on the LAPACK installation problem on my system. It odd to
me because I used the Fortran LAPACK downloaded and installed
automatically by Petsc. Do you have any suggestions regarding this
problem?

Also, the BLOPEX solver is supported directly by Petsc. Do you think
we still need Slepc to call it from libmesh?

Thanks,

David
