Hello Folks,
i am just leanring roscpp and i want to re-write the [Simple Publisher and Subscriber](http://wiki.ros.org/ROS/Tutorials/WritingPublisherSubscriber(c%2B%2B)) Tutorial with an integer instead of a string. So how have i to write the callback function?
void chatterCallback(const std_msgs::UInt16 msg)
{
ROS_INFO("I heard: [%d]", msg->data);}
}
But `catkin_make` says:
error: ‘UInt16’ was not declared in this scope
Have i missed some additional headers so `std_msgs/UInt16` message isn't declared yet?
The same problem also appears also for `ros::Publisher chatter_pub = n.advertise("test", 5);`.
Someone has a hint for me?
