[petsc-users] [SLEPc] ex5 fails, error in lapack

[Santiago Andres Triana]

Hi Dave,

Indeed, I added that last arg myself after the configure script asked for
it (--with-batch seems to need it). I just tried with petsc-3.9.1, without
the --with-batch and --known-64-blas-indices=1 options and everything is
working nicely. I will try again later with the latest version.

Thanks!

Santiago
