Error loading my rqt plugin from rqt_gui

Hello! I have written a quick rqt plugin, starting with the roscreate-qt-pkg command to create a package and then following the rqt tutorials. When trying to load the plugin in rqt_gui, I get the following error: "Failed to load nodelet [control_centre/MyPlugin_1] of type [control_centre/MyPlugin]: Failed to load library /home/pioneer/ros_workspace/control_centre/lib/libcontrol_centre.so. Make sure that you are calling the PLUGINLIB_REGISTER_CLASS macro in the library code, and that names are consistent between this macro and your XML. Error string: Cannot load library: No manifest in /home/pioneer/ros_workspace/control_centre/lib/libcontrol_centre.so: control_centre__MyPlugin" I am using ROS fuerte on Ubuntu 12.04. My manifest.xml is the following: ... My plugin.xml is the following: Controls for toggling various rescueneer robot features.Rescueneer Control Centresystem-help.. My CMakeLists.txt is the following: ############################################################################## # Rosbuild2 ############################################################################## if(ROSBUILD) include(rosbuild.cmake OPTIONAL) return() endif() ############################################################################## # CMake ############################################################################## cmake_minimum_required(VERSION 2.4.6) ############################################################################## # Ros Initialisation ############################################################################## include($ENV{ROS_ROOT}/core/rosbuild/rosbuild.cmake) rosbuild_init() #set the default path for built executables to the "bin" directory set(EXECUTABLE_OUTPUT_PATH ${PROJECT_SOURCE_DIR}/bin) #set the default path for built libraries to the "lib" directory set(LIBRARY_OUTPUT_PATH ${PROJECT_SOURCE_DIR}/lib) #include_directories( ${PROJECT_SOURCE_DIR}/include/control_centre ) # Set the build type.

The code compiles and I can run it as a stand-alone application, but I can't seem to open it in rqt_gui. Thanks!
