First post. Please be gentle. I cannot seem to find a package to install OpenCL platforms for Fedora 37. I am using NVIDIA version 525.8902 on GeForce GTX 1660 TI in dedicated GPU (turned off Intel) mode on Lenovo Legion 5 laptop. darktable-cltest indicates it finds libOpenCL.so.1 but could not get platforms: Unknown OpenCL error.
Do you have secure boot on?
How did you install NVidia driver? I used RPMFusion repo and followed their Nvidia howto steps

$ rpm -qa|grep nvidia

I see the cuda-libs but not just the cuda.
Try this and restart the computer.
sudo dnf install xorg-x11-drv-nvidia-cuda
Worked. OpenCL successfully initialized. Thanks. Not sure how I was supposed to figure that out. No hints given by cltest.
It is part of the rpm fusion link that was provided above. It is not a darktable issue.
g-man,
You are, of course, correct. Thanks for the hand spank (sincerely).
40 years of building software make me acutely aware that one does not always have visibility into the nuances of architectural layers below those with which one directly interfaces. My comment was made out of frustration, not criticism. Not being an expert in OpenCl, and having never written code that uses it’s API, my hope was that darktable would point me to the error of my ways and suggest what it was looking for that was not found in a manner that would enlighten this newbie adventurer into that space. I accept full responsibility for not having an intimate knowledge of OpenCL and its boundaries with darketable, of which I am quickly becoming a huge fan.
It is always good to learn from those with more experience. Thus the value of this platform. Unfortunately, sometimes one don’t know what one does not know. Party on Garth.
