Create octree

edit

Hi!

This question is really simple I think but I can't figure it out. This code:

#include <octomap_msgs/Octomap.h>//Octomap Binary
#include <octomap/OcTree.h>
#include <octomap_msgs/conversions.h>

int main(int argc, char **argv)
{
  ros::init(argc, argv, "mapper");
  ros::NodeHandle n;
  octomap::OcTree* octomap_ = new octomap::OcTree(0.1f);
  ros::spin();
  return 0;
}

Gives this compile error

CMakeFiles/mapper_node.dir/src/nodes/mapper_node.cpp.o: In function `octomath::Pose6D::Pose6D(octomath::Pose6D const&)':

Isn't this the simplest possible initialization? What am I missing?
