Trying to narrow down my problem: Having problem with the default hw simulator plugin. System can find the gazebo plugin xml and the plugin shared lib but keeps failing to load. I tried to start gazebo with the plugin directly and I get the following error: Can anyone give some insight. System is ros hydro with gazebo 1.9: plugins compiled from source in catkin. Error is similar when starting rrbot demo. But the error from the demo is not as informative.
