Failure to build with hipcc support

[luyatshimbalanga]

When using HIPcc option to build OIDN, failure happened from the log extract:

-- Check for working CXX compiler: /usr/bin/hipcc - broken
CMake Error at /usr/share/cmake/Modules/CMakeTestCXXCompiler.cmake:60 (message):
  The C++ compiler

    "/usr/bin/hipcc"

  is not able to compile a simple test program.

  It fails with the following output:

What exactly do you mean by "HIPcc option"? How exactly do you invoke CMake? What version of ROCm are you using?

[luyatshimbalanga]

Adding -DOIDN_DEVICE_HIP_COMPILER=%{_bindir}/hipcc \ in supplement to -DOIDN_DEVICE_HIP=ON \ running on ROCm 6.0

[atafra]

You shouldn't manually set OIDN_DEVICE_HIP_COMPILER. The ROCm path should be automatically detected. It isn't? If it's not detected, you should rather set ROCM_PATH instead. In any case, ROCm's clang++ should be used (which should be detected automatically) instead of hipcc.

[luyatshimbalanga]

Thanks for the pointer. After setting ROCM_PATH and had to manually apply OIDN_DEVICE_HIP_COMPILER to use clang++-17 (version 17 on Fedora which use version 18 by default), the build failed at the following line:

It looks like the failure occurred for gfx1030 line.
I include the build.log for reference.

Why did you have to set OIDN_DEVICE_HIP_COMPILER? This isn't necessary with a regular installation of ROCm (tested with versions between 5.5.0 and 6.1.0). Also, you set it to /usr/bin/clang++-17, which seems to be the system Clang instead of ROCm's own Clang. That won't work.

Please follow the ROCm install instructions at https://rocm.docs.amd.com/projects/install-on-linux/en/latest/
Currently this is the only supported ROCm installation method by OIDN.
