global_planner is not registered [closed]

edit

I am trying to use the global_planner, I added it in move_base parameters as

base_global_planner: global_planner/PlannerCore

but it keeps saying this planner is not registered. Is there a special way to register it?

These are the errors:

Using the deb (/opt/ros/hydro/share/global_planner)

Exception: According to the loaded plugin descriptions the class global_planner/PlannerCore with base class type nav_core::BaseGlobalPlanner does not exist. Declared types are  SBPLLatticePlanner carrot_planner/CarrotPlanner goal_passer/GoalPasser iri_bspline_navfn/NavfnROS navfn/NavfnROS

If I try using an overlay (catkin_ws/navigation/global_planner)
