The boinc package has a USE=cuda flag which pulls in dev-util/nvidia-cuda-toolkit but this is not actually necessary to run CUDA tasks in boinc. The required libraries are already provided by x11-drivers/nvidia-drivers $ equery f x11-drivers/nvidia-drivers | grep libcuda.so /usr/lib/libcuda.so /usr/lib/libcuda.so.1 /usr/lib/libcuda.so.470.63.01 /usr/lib64/libcuda.so /usr/lib64/libcuda.so.1 /usr/lib64/libcuda.so.470.63.01 However, virtual/opencl does need to be installed in order to run OpenCL tasks (nvidia-drivers can run both CUDA and OpenCL tasks). Suggestion: remove the USE=cuda flag and add a USE=opencl flag which adds a dependency on virtual/opencl. Reproducible: Always
Actually, USE=cuda is useful to pull in x11-drivers/nvidia-drivers but I still think the dev-util/nvidia-cuda-toolkit dependency is unnecessary and should be dropped.
I'll try this out on my machine. I wanted to bump the client anyway.
Will be done shortly cuda USE flags stays, opencl USE flag is added. VIDEO_CARDS will be heeded. I really like it that neither the cg-toolkit nor the cuda-toolkit are needed any more. Those are giant monsters!
