Hi,

I'm getting started learning actionlib, and have the example from the tutorials working just fine, and I thought I understood it pretty well. I'm trying to implement a second server (Called counter_server, based on a Counter.action file) so I can learn it better, and am having some trouble.

Quick note, running ROS melodic in ubuntu 18.04 in a VMware VM.

When compiling, this is the error I get:

/home/me/catkinws/src/actionlibtutorials/src/counterserver.cpp:3:10: fatal error: actionlibtutorials/CounterAction.h: No such file or directory

 #include <actionlib_tutorials/CounterAction.h>
          ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

I suspect some sort of a cmake error. This is all of my CMakeLists:

This is the code in counter_server.cpp, but it seems like pretty straightforward C++ and is extremely similar to the code from the tutorial.

#include <ros/ros.h>
#include <actionlib/server/simple_action_server.h>
#include <actionlib_tutorials/CounterAction.h>


class CounterAction{

protected:

  ros::NodeHandle nh_;
  actionlib::SimpleActionServer<actionlib_tutorials::CounterAction> as_;

  std::string action_name_;

  actionlib_tutorials::CounterFeedback feedback_;
  actionlib_tutorial::CounterResult result_

public:

  CounterAction(std::string name): as_(nh, name, boost::bind(&FibonacciAction::executeCB, this, 1),false),
  action_name_(name){
    as_.start();
  }

  ~FibonacciAction(void){}

  void executeCB(const actionlib_tutorials::CounterGoalConstPtr& goal){

    ros::Rate r(1);
    bool success = true;
    int sum = 0;

    ROS_INFO("Starting counter");

    for(int i = 0; i < goal->maxVal; ++i){
      if(as_.isPreeptRequested() || !ros::ok()){
        ROS_INFO("Preempted");
        as_.setPreempted;
        success = false;
        break;
      }
      sum += i;
      feedback_.currentVal = i;
      as_.publishFeedback(feedback_);

      r.sleep();

    }

    if(success){
      result_.sum = sum;
      ROS_INFO("yay did a count");
      as_.setSucceeded(result_);
    }
  }

};

int main(int arcg, char** argv){
  ros::init(argc, argv, "counter");
  CounterAction counter("counter");
  ros::spin();
  return 0;
}



)

I hope you can help! Thanks!
