Hi Tomas,
Thanks for your input. For me, OpenCL is now working, (nearly)
without workarounds, using the packages from Debian testing (nvidia
driver v. 340).
My steps:
- Debian testing, ocl-icd-libopencl1 is providing
libOpenCL.so.1
- Purge all nvidia packages
- Reboot (to console)
- Install nvidia-driver and nvidia-opencl-icd
- At this point clinfo shows OpenCL support, darktable
can’t use it
- Install nvidia-cuda-toolkit (or probably any other OpenCL
development package)
Now darktable can use OpenCL.
Thanks Micheal, I never came so close to get OpenCL working, after
months (I didn't put much effort though). Purging and reinstalling
seemed to work.
I had to install also libopencl-dev to make it work. And I previously
created the symlink libOpenCL.so.
Now I get this:
$ darktable -d opencl
