2016-09-17 11:29:17 -0500	asked a question	failed to load library when running a realtime joint controller Hello,everyone! I'm learning this tutorial Running a realtime joint controller to create a basic real-time joint controller. Everything is okay until I reach this step: 3.3.1 Load If everything looks good, let's try to load our controller: `$ rosrun pr2_controller_manager pr2_controller_manager load my_controller_name` After using above command, I get an error : [ERROR] [1474085129.430380858, 74.606000000]: Could not load class my_controller_pkg/MyControllerPlugin: Failed to load library /home/hadoop436/catkin_ws/devel/lib//libmy_controller_lib.so. 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 = /home/hadoop436/catkin_ws/devel/lib//libmy_controller_lib.so: undefined symbol: _ZN14console_bridge14log_deprecatedEPKciNS_8LogLevelES1_z) [ERROR] [1474085129.430493719, 74.606000000]: Could not load controller 'my_controller_name' because controller type 'my_controller_pkg/MyControllerPlugin' does not exist I suspect the library path of the plugin is wrong because the path is /home/hadoop436/catkin_ws/devel/lib//libmy_controller_lib.so. I ensure that the controller is configured as a plugin and got registered to the controller manager. who can help me to solve this problem?
