Wow. Thank you for the tip, CL_CHECK is now giving me an output. This is the error message: (lt-gegl:10486): GEGL-video-degradation.c-WARNING **: Error in video-degradation.c:236@cl_process - invalid kernel
I thought that I had followed the kernel compilation process correctly. Do you notice any mistake? I have pushed my latest change to the branch.
