media-gfx/darktable cannot initialize OpenCL support with latest nvidia-drivers. $ darktable -d opencl [opencl_init] trying to load opencl library: '<system default>' [opencl_init] opencl library 'libOpenCL' found on your system and loaded [opencl_init] could not get platforms: -1001 [opencl_init] FINALLY: opencl is NOT AVAILABLE on this system. [opencl_init] initial status of opencl enabled flag is OFF. OpenCL works well with 2XX.XX series of nvidia-drivers. I asked about this problem in darktable-devel mailing list. They claim that 1) https://sourceforge.net/mailarchive/message.php?msg_id=29694734 ... error code -1001 is typical for NVIDIA drivers if there is an installation problem. Maybe the CUDA runtime cannot be found or a version mismatch. 2) https://sourceforge.net/mailarchive/message.php?msg_id=29695325 https://sourceforge.net/mailarchive/message.php?msg_id=29695412 ... 304.37 is also the version shipped with Ubuntu 12.04 (driver updated a few days ago) works perfectly well with DT. # emerge --info Portage 2.1.11.10 (default/linux/x86/10.0/desktop, gcc-4.5.4,

Comparing with files installed by Ubuntu https://sourceforge.net/mailarchive/message.php?msg_id=29695412 and Arch https://www.archlinux.org/packages/extra/i686/opencl-nvidia/ it seems that gentoo ebuild does not install /usr/lib/libnvidia-opencl.so.304.37 (and also libnvidia-wfb.so.304.37 but perhaps this is an another problem) This seems to be a source of the problem.
I just have verified that installing of /usr/lib/libnvidia-opencl.so.304.37 and substituting of /usr/lib/libnvidia-opencl.so instead of /usr/lib/libcuda.so in /etc/OpenCL/vendors/nvidia.icd fixes the bug. I am not sure what is libnvidia-wfb.so.304.37
Created attachment 321726 [details] corrected ebuild I attach the ebuild fixing the bug

The OpenCL issue also breaks boinc.
Fixed in 304.37-r1.
