Public bug reported:
OpenCL is not enabled by default.
Steps to reproduce :
* install the nvidia driver
* install darktable
* run darktable on command line : $darktable -d opencl
=>
[opencl_init] could not find opencl runtime library 'libOpenCL'
0.159268 [opencl_init] could not find opencl runtime library 'libOpenCL.so'
0.159327 [opencl_init] could not find opencl runtime library 'libOpenCL.so.1'
0.159333 [opencl_init] no working opencl library found. Continue with opencl
disabled
0.159336 [opencl_init] FINALLY: opencl is NOT AVAILABLE on this system.
Workaround : install package nvidia-opencl-dev
Should darktable depend on nvidia-opencl-dev ?
