[petsc-users] Petsc with Elemental installation in Cray

[venkatesh g]

Hi, when I use --with-cxx-dialect=C++11, I get the error

Could not determine compiler flag for with-cxx-dialect=C++11, use CXXFLAGS

Kindly let me know the syntax or how to enable this.

w.r.t --with-mpi-dir on Crays, I will keep it in mind and will not pass
them as you have told Barry, they locate it automatically.

Thank you
Venkatesh
