I use Ubuntu 20.04 and ROS Noetic. I built rviz from source (with newer version of Ogre) and after that the jsk_rviz_plugin/Plotter2D does not load any more. I checked that my new rviz workspace is sourced and everything else regarding rviz seems to work fine. I checked with rospack find and the jsk_rviz_plugins is not found any more. How can it get lost and how can I avoid it happen?
