بسم الله الرحمن الرحيمHello,also i got an errors when i use mpiicpc compiler - in the final step (linking step) - like:/usr/include/c++/5/bits/char_
traits.h:290: undefined reference to `_intel_fast_memcpy'
algobase.h:770: undefined reference to `_intel_fast_memset'and more ...now i have errors with both compilers ...please i need some help to compile lammps with kokkos.Thanks a lot.On Thu, Oct 12, 2017 at 1:38 AM, A.
