error: ‘Octree2BufBase’ was not declared in this scope

Your Environment

• Operating System and version: Ubuntu 16.04
• Compiler: Cmake
• PCL Version: 1.7.0

Context

I am trying to initialize an OctreePointCloudChangeDetector with the following code:

#include <pcl/point_cloud.h>
#include <pcl/octree/octree_pointcloud_changedetector.h>
#include <pcl/octree/octree_pointcloud_density.h>
#include <pcl/octree/octree2buf_base.h>
#include <iostream>
#include <vector>
#include <ctime>


int
main (int argc, char** argv)
{
  srand ((unsigned int) time (NULL));

  // Octree resolution - side length of octree voxels
  float resolution = 32.0f;

  // Instantiate octree-based point cloud change detection class
  pcl::octree::OctreePointCloudChangeDetector<pcl::PointXYZ> octree (resolution);
}

But while compiling this error appears:

/usr/include/pcl-1.7/pcl/octree/octree_pointcloud_changedetector.h:64:43: error: ‘Octree2BufBase’ was not declared in this scope
LeafContainerT, BranchContainerT, Octree2BufBase<LeafContainerT, BranchContainerT>>

I think the issue might be caused by a wrong initialization of the object but I don't know how to initialize it.
Can you help me with the issue?? Thank you

In usr/include/pcl-1.7/pcl/octree the header "octree_pointcloud_changedetector.h" misses an include of the header octree2buf_base.h

CHANGELOG (in "octree_pointcloud_changedetector.h") -> add #include "octree2buf_base.h"
