I was running a Moveit tutorial on Motion Planning (ROS Indigo version) when I got the error,

The class required for this display, 'moveit_rviz_plugin/MotionPlanning', could not be loaded.
Failed to load library /opt/ros/indigo/lib/ Make sure that you are calling the PLUGINLIB_EXPORT_CLASS macro in the library code, and that names are consistent between this macro and your XML. Error string: Could not load library (Poco exception = cannot open shared object file: No such file or directory)

The first time when I launched the tutorial, I got a similar error and fixed it by

sudo apt-get update
sudo apt-get dist-upgrade

as suggested in Rviz motion_planning Error: Failed to load library, but has not worked since.

I have installed opencv3.2.0, is that the reason why this isn't working? Or is the opencv plugin a part of ROS? I checked the library files in Moveit and this is the output:-

>> ls /opt/ros/indigo/lib | grep open

>> ls /opt/ros/indigo/lib | grep motion

>> ls /usr/local/lib | grep

Is there a way to make RViz use the 3.2 version instead?

Any help would be appreciated. Thanks in advance.

It looks like the plugin is compiled against packages that use OpenCV 2.4, and can't be used with a different version. You may be able to recompile the moveit rviz plugin with the updated version of OpenCV
