The /usr/share/doc/nvidia-cuda-sdk-9.1.85 directory is present. It contains a bunch of readme.txt with the description of what the example is supposed to do, but such an example (the source code) is not present. Here's the content of such directory: - https://paste.pound-python.org/show/sKnMXYC1eu8s2shg2Fob/ Reproducible: Always Steps to Reproduce: Emerge =dev-util/nvidia-cuda-sdk-9.1.85 with the +examples USE flag
All CUDA related stuff is installed to /opt/cuda/, only the documentation is not. The binaries as well as the source code of the examples are located at /opt/cuda/sdk.
