Description
Describe the bug
When attempting to build LAMMPS with Kokkos, I am experiencing silent failures of the offload bundling, due to a mismatch in targets. The offload bundler call is:
"/soft/llvm/bin/clang-offload-bundler" "-type=o" "-targets=host-x86_64-unknown-linux-gnu,sycl-nvptx64-nvidia-cuda" "-inputs=CMakeFiles/lmp.dir/home/joe/sources/lammps_stack/lammps/src/main.cpp.o" "-outputs=/tmp/main-335138.o,/tmp/main-967baf.o" "-unbundle" "-allow-missing-bundles"
but later:
"/soft/llvm/bin/clang-offload-deps" "-targets=sycl-nvptx64-nvidia-cuda--sm_80" "-outputs=/tmp/-fffb95.bc" "/tmp/-7e2d11.out"
Note the additional (erroneous?) --sm_80 which means nothing is found.
To Reproduce
I've tried to make a reproducer but have been unable, I'm afraid. So, building LAMMPS is required.
Environment (please complete the following information):
- OS: Linux
- Target device and vendor: Nvidia GPU
- DPC++ version: Introduced in merge fc2f897
Additional context
I believe @AidanBeltonS has an upcoming PR which solves this issue.
