Hi, oh, your reply on 24. Sep. 2013 was addressed only to 720...@bugs.debian.org and wasn't being cc'ed, so I have not received a copy of it.
On Christmas holidays I've tried to build opencv with opencl support on Debian Jessie without(!) proprietary OpenCL SDK. It is enough to install just 2 additional packages: ocl-icd-dev and ocl-icd-opencl-dev in make opencv automatically discover a presence of OpenCL support and enable building the ocl module. So you could for now just extend build-depends on these 2 packages from main. There will be no proprietary/contrib dependencies for installing the future package libopencv-ocl. Once one needs to use it, then only these users will have to install some non-free OpenCL ICD from amd/intel/nvidia. Or(!) one can install locally some free (though not 100% functioning) OpenCL ICD and use it. I can't see no impacts on the opencv ocl module itself. This was the idea of OpenCL ICD: one can link to the loader (e.g. libOpenCL.so from ocl-icd-libopencl1) but then use a proprietary one. If it works out with Gallium - it would be great! But the main thing for now is to have the ocl module packaged and then one can experiment with the either OpenCL implementation.
