[petsc-dev] Fwd: [petsc-users] configure error on Titan with Intel

[Mark Adams]

We have Titan working but we have a problem that we need lstdc++ to get
PETSc to configure.  Otherwise it fails to build fortran.  This seems to
only be needed for GNU.  This is for PGI.  If we remove this C++ works,
otherwise there is a missing external.  I guess I can just deploy two
version, on for fortran and one for C++ (I have a C++ and a fortran code
that I support).
