Hi,

yeah I think I include the correct header files:


#include "ros/ros.h"
#include "sensor_msgs/PointCloud.h"
#include "sensor_msgs/PointCloud2.h"
#include "message_filters/subscriber.h"
#include "pcl/io/pcd_io.h"
#include "pcl/point_types.h"

and dependencies"

  <depend package="roscpp"/>
  <depend package="ptu_46"/>
  <depend package="pcl"/>
  <depend package="pcl_ros"/>
  <depend package="geometry_msgs"/>
  <depend package="sensor_msgs"/>

  
or am I missing something?
