OK! I found what was wrong: I did not rboot after installing the cuda
package and the udev rule was not taken into account

Problem is solved now! Thank you for having pointed this module!

Seems a package containing this is missing: ptxjitcompiler

[darktable-user] how to enable opencl in darktable

[François Patte]

Bonjour,

I try to use opencl with darktable.

I have an nvidia geforce gtx 1050 ti graphic card, using the nvidia
proprietary driver on fedora 27.

launching darktable -d opencl returns:

[opencl_init] could not find opencl runtime library 'libOpenCL'
[opencl_init] could not find opencl runtime library 'libOpenCL.so'
[opencl_init] found opencl runtime library 'libOpenCL.so.1'
[opencl_init] opencl library 'libOpenCL.so.1' found on your system and
loaded
[opencl_init] found 2 platforms
[opencl_init] could not get device id size: -1
[opencl_init] found 1 device
[opencl_init] discarding CPU device 0 `pthread-Intel(R) Core(TM) i5-3330
CPU @ 3.00GHz'.
[opencl_init] no suitable devices found.
[opencl_init] FINALLY: opencl is NOT AVAILABLE on this system.
[opencl_init] initial status of opencl enabled flag is OFF.
[pixelpipe_process] [thumbnail] using device -1


Who can help me?

Thank you.
