Hi, I tried to follow your code on SimpleActionClient but I encountered this error /home/shuttle/ros/stacks/ros_tutorials/simple_navigation_goal/src/simple_navigation_goal.cpp:3:49: error: actionlib_tutorials/FibonacciAction.h: No such file or directory /home/shuttle/ros/stacks/ros_tutorials/simple_navigation_goal/src/simple_navigation_goal.cpp:5: error: ‘actionlib_tutorials’ is not a namespace-name /home/shuttle/ros/stacks/ros_tutorials/simple_navigation_goal/src/simple_navigation_goal.cpp:5: error: expected namespace-name before ‘;’ token /home/shuttle/ros/stacks/ros_tutorials/simple_navigation_goal/src/simple_navigation_goal.cpp:6: error: ‘FibonacciAction’ was not declared in this scope /home/shuttle/ros/stacks/ros_tutorials/simple_navigation_goal/src/simple_navigation_goal.cpp:6: error: template argument 1 is invalid /home/shuttle/ros/stacks/ros_tutorials/simple_navigation_goal/src/simple_navigation_goal.cpp:6: error: invalid type in declaration before ‘;’ token /home/shuttle/ros/stacks/ros_tutorials/simple_navigation_goal/src/simple_navigation_goal.cpp:10: error: ISO C++ forbids declaration of ‘FibonacciResultConstPtr’ with no type /home/shuttle/ros/stacks/ros_tutorials/simple_navigation_goal/src/simple_navigation_goal.cpp:10: error: expected ‘,’ or ‘...’ before ‘&’ token /home/shuttle/ros/stacks/ros_tutorials/simple_navigation_goal/src/simple_navigation_goal.cpp: In function ‘void doneCb(const actionlib::SimpleClientGoalState&, int)’: /home/shuttle/ros/stacks/ros_tutorials/simple_navigation_goal/src/simple_navigation_goal.cpp:12: error: ‘result’ was not declared in this scope /home/shuttle/ros/stacks/ros_tutorials/simple_navigation_goal/src/simple_navigation_goal.cpp: At global scope: /home/shuttle/ros/stacks/ros_tutorials/simple_navigation_goal/src/simple_navigation_goal.cpp:24: error: ISO C++ forbids declaration of ‘FibonacciFeedbackConstPtr’ with no type /home/shuttle/ros/stacks/ros_tutorials/simple_navigation_goal/src/simple_navigation_goal.cpp:24: error: expected ‘,’ or ‘...’ before ‘&’ token /home/shuttle/ros/stacks/ros_tutorials/simple_navigation_goal/src/simple_navigation_goal.cpp: In function ‘void feedbackCb(int)’: /home/shuttle/ros/stacks/ros_tutorials/simple_navigation_goal/src/simple_navigation_goal.cpp:25: error: ‘feedback’ was not declared in this scope /home/shuttle/ros/stacks/ros_tutorials/simple_navigation_goal/src/simple_navigation_goal.cpp: In function ‘int main(int, char**)’: /home/shuttle/ros/stacks/ros_tutorials/simple_navigation_goal/src/simple_navigation_goal.cpp:32: error: initializer expression list treated as compound expression /home/shuttle/ros/stacks/ros_tutorials/simple_navigation_goal/src/simple_navigation_goal.cpp:32: warning: left-hand operand of comma has no effect /home/shuttle/ros/stacks/ros_tutorials/simple_navigation_goal/src/simple_navigation_goal.cpp:35: error: request for member ‘waitForServer’ in ‘ac’, which is of non-class type ‘Client’ /home/shuttle/ros/stacks/ros_tutorials/simple_navigation_goal/src/simple_navigation_goal.cpp:39: error: ‘FibonacciGoal’ was not declared in this scope /home/shuttle/ros/stacks/ros_tutorials/simple_navigation_goal/src/simple_navigation_goal.cpp:39: error: expected ‘;’ before ‘goal’ /home/shuttle/ros/stacks/ros_tutorials/simple_navigation_goal/src/simple_navigation_goal.cpp:40: error: ‘goal’ was not declared in this scope /home/shuttle/ros/stacks/ros_tutorials/simple_navigation_goal/src/simple_navigation_goal.cpp:41: error: request for member ‘sendGoal’ in ‘ac’, which is of non-class type ‘Client’ How do I include the header file in?
