Unknown argument '-hc' found while linking to hip::device #27

I was trying to run the example openmp-helloworld with HIP 3.9.1 and an error occurred.

The compiler I was using is not in the default installation path /opt/rocm so I commented out the compiler setting statements in the original CMakeLists.txt. It seems like the target hip::device cmake found is still from the default installation of ROCm. This target comes with a flag -hc which breaks the build.

$ cmake -S . -B build -DCMAKE_C_COMPILER=hipcc -DCMAKE_CXX_COMPILER=hipcc && cmake --build build -v
