Compilation error when building LAMMPS pair_flare_kokkos

[namehta4]

Hi,

I am trying to build pair flare inside a lammps container for our users on Perlmutter.
I have encountered the following error during compilation:

[ 95%] Building CXX object CMakeFiles/lammps.dir/opt/lammps/src/KOKKOS/pair_flare_kokkos.cpp.o
/opt/lammps/build/_deps/kokkoskernels-src/common/src/Kokkos_ArithTraits.hpp(871): error: class "Kokkos::Experimental::finite_min<Kokkos::Experimental::half_t>" has no member "value"

/opt/lammps/build/_deps/kokkoskernels-src/common/src/Kokkos_ArithTraits.hpp(871): error: class "Kokkos::Experimental::finite_max<Kokkos::Experimental::half_t>" has no member "value"

with more similar error messages.

I am using Kokkos kernel :

May I please request your help with this error?

Thank you!

Hi Neil,

This is, indirectly, caused by the old LAMMPS version, see #366.

The easiest solution is to use a newer version of LAMMPS; our weekly CI pulls the latest release. Alternatively, you can modify CMakeLists.txt as shown in the above issue.

Hi Anders,

Thank you for your comment.
I will retry building the image.

Thank you!
