Hi. Thanks for sharing this.
I've run roslaunch turtlebot_rrt rrt_planner.launch,have a error.
Failed to create the turtlebot_rrt/RRTPlanner planner, are you sure it is properly registered and that the containing library is
built? Exception: Failed to load library /home/tree/rosten/devel/lib//libturtlebot_rrt.so. Make sure that you are calling the PLUGINLIB_EXPORT_CLASS macro in the library cod
e, and that names are consistent between this macro and your XML. Error string: Could not load library (Poco exception = /home/tree/rosten/devel/lib//libturtlebot_rrt.so: und
efined symbol: _ZN12class_loader20class_loader_private30getCurrentlyLoadingLibraryNameEv)
Can you guide me to solve this problem?
