Has anyone encountered this : error: no type named ‘_action_goal_type’ in ‘struct move_base_msgs::MoveBaseActionGoal_<std::allocator<void> >’ typedef typename ActionSpec::_action_goal_type ActionGoal; \
I am using the move_base server in my project. So I need to send an action goal. But implementing the actionlib part is giving this error for all the micros in its header files. What should be done?
