Does anybody succeeded to get OpenCL support for Darktable working? As far as I know, OpenCL support in darktable does work on Apple ARM silicon, so I hope it might be achievable for Rock 5 too. OpenCL seems to be available in my system, clinfo gives the expected output, clpeak measures the performance.
When I launch darktable, it looks fine at the beginning as it finds OpenCL in the system. So far so good. But then it fails to compile the OpenCL kernel, see the output below. And I’m totally out of idea to tell why, because it complains about invalid build options which are out of my control and about failing to open the directory with the CL kernel sources. But this directory does exist and is user accessible.
I’m using the panfork driver and running Wayland. Should I use the ARM blob instead? If so, how to switch?
Many thanks for any idea!
