[petsc-users] Petsc with Elemental installation in Cray

[venkatesh g]

Hi all,

I am trying to install elemental with Petsc.

I configure using:

./configure --with-cc=gcc --with-cxx=g++ PETSC_ARCH=linux-intel_elemental
-with-blas-lapack-dir=/opt/intel/composer_xe_2015.1.133/mkl/lib/intel64/
--with-mpi-dir=/opt/cray/mpt/7.0.5/gni/mpich2-intel/140
--with-scalar-type=complex --with-fortran-kernels=1
-known-mpi-shared-libraries=0 --with-large-file-io=1
--with-64-bit-indices=0 --with-batch FC=ifort
--with-valgrind-dir=/mnt/lustre/esd2/esdveng/valgrind
--download-elemental=/home/proj/14/esdveng/apps/Elemental-0.84-p5.tgz
--download-cmake=/home/proj/14/esdveng/apps/cmake-2.8.12.2.tar.gz

I get this error:

Cannot use elemental without enabling C++11, see --with-cxx-dialect=C++11

Pls let me know what flag must I use and its syntax.

Venkatesh
