Ubantu16.04 When I run the command rosrun kinect2_viewer kinect2_viewer it shows: /home/cyc/catkin_ws/devel/lib/kinect2_viewer/kinect2_viewer: /usr/local/cuda-8.0/lib64/libOpenCL.so.1: no version information available (required by /home/cyc/catkin_ws/devel/lib/libkinect2_registration.so) /home/cyc/catkin_ws/devel/lib/kinect2_viewer/kinect2_viewer: /usr/local/cuda-8.0/lib64/libOpenCL.so.1: no version information available (required by /home/cyc/catkin_ws/devel/lib/libkinect2_registration.so) Segmentation fault (core dumped)

I was able to fix this by uninstalling OpenCL. Then I had to delete my build folders for libfreenect 2 (including $HOME/freenect2) and then reinstalling libfreenect2 again (do cmake, make, make install, etc). Then I did catkin_make for iai_kinect2 and everything worked.
