Hi Steffen,
First, thanks for bringing this issue to my attention! The omission
of octree from the perception_pcl was an accident, and I'm really glad
you let me know about it.
Second, the linker error you found when trying to use
OctreePointCloudSinglePoint is present in the stand-alone version of
PCL as well as in ROS, so it appears to be a bug in PCL 1.1. Not sure
what the problem is yet, but I'll look into it.
