Package: clang Version: 1:13.0-54 Severity: normal Dear Maintainer,
The upstream versions of clang-13 and clang-14 fulfill the minimum requirements to build HIP language programs, but contain a bug that prevents them from functioning correctly when the HIP library is installed in /usr. This problem was fixed in upstream llvm, and the change is expected to land in clang-15. The change is very minimal and only affects the HIP language. It can be found here: https://github.com/llvm/llvm-project/commit/6730b44480fcce18bfbbae0c46719250e9eae425 This problem is important to address to help the packaging of ROCm proceed, as the Debian native package will install HIP into /usr. To reproduce the problem: # install HIP to /usr https://gist.github.com/cgmb/edb7b790ab55681fb2ba5385ee02489b # create a HIP language program cat > example.cpp << 'EOF' #include <hip/hip_runtime.h>
