hi everyone,
Now I try this tutorial Coding a realtime Cartesian controller with
KDL(http://www.ros.org/wiki/pr2_mechanism/Tutorials/Coding%20a%20realtime%20Cartesian%20controller%20with%20KDL),
but when I compiled the source code, it always gives me these errors:
/home/cob/ros/ros-tutorials/ros_pkg_tutorials/my_controller_pkg/src/my_cart_controller_file.cpp:

my_controller_ns::MyCartControllerClass::init(pr2_mechanism_model::RobotState*,
ros::NodeHandle&)’:

Does anybody know how to solve this problem?
Thank you in advance!
