Build error for Kokkos::Cuda backend

[pkestene]

I'm trying to build current main branch against kokkos with cuda backend activated.

I've encountered at least two errors for which I would need help:

1. about Kokkos_TrackDuplicates.hpp

   [ 48%] Building CXX object tests/CMakeFiles/resilience_tests.dir/TestResilience.cpp.o
   In file included from /data/pkestene/install/trilinos/kokkos/github/kokkos-resilience_pk/tests/TestResilience.cpp:45:

   make[1]: *** [CMakeFiles/Makefile2:485: tests/CMakeFiles/resilience_tests.dir/all] Error 2
   make: *** [Makefile:146: all] Error 2

   I'm not able to find header Kokkos_TrackDuplicates.hpp in kokkos sources even with git grep.

2. about header impl/Kokkos_Tags.hpp

   [ 46%] Building CXX object tests/CMakeFiles/resilience_tests.dir/TestResilience.cpp.o
   In file included from /data/pkestene/install/trilinos/kokkos/github/kokkos-resilience_pk/tests/TestResilience.cpp:46:

   61 | #include <impl/Kokkos_Tags.hpp>
     |          ^~~~~~~~~~~~~~~~~~~~~~
   compilation terminated.

   header impl/Kokkos_Tags.hpp exists in Kokkos sources, but it is not installed anymore.

These errors are trigger when I use kokkos 4.1.00

Which version / git hash of Kokkos do you recommend ?

Thanks for reporting this. Quick question -- are you intending to use Cuda Resilient Execution Spaces? They are currently still very much work in progress. The build script unfortunately enables them automatically, so I can make a fix to turn them off.
