Hi,
I tried to enable opencl on my notebook with dedicated graphic card.
In most cases this fails (yes, sometimes, very rare, it is enabled, but
after restarting the computer or even darktable, it's disabled)
It doesn't matter if running on onboard or dedicated GPU.
Debug shows a compile/build error and that's why I report to you.
