How to enable OpenCl in darktable on ubuntu

Software darktable
1

I have a PC with dual GPU (onboard Intel Alder lake an an Intel Arc A770) I installed all driver-Packages from Intel : 2.1. Overview — Intel® software for general purpose GPU capabilities documentation.
Darktable is finding the ‘libOpenCL’
The output from darktable-cltest is:

darktable-cltest.txt (1.4 KB)

and the output from clinfo is:
CLinfo.txt (62.2 KB)

darktable recognizes the Intel_driver I think:
8a254d674950b2a4d6ff97aa7d54d65a7ef2a62b_2_616x500

What can I do else to enable OpenCl?

This is the platform check that is stopping the use of OpenCL. It is detecting two platforms that are the same (Intel). The intent of the check was to prevent system that had multiple drivers for the same card. In your case, you have two different intel.

I noticed your GitHub post. Lets continue the conversation there.
