ar_track_alvar MarkerlessDetector issue

edit

This is a cpp for markerless detection and creation. Has anyone gotten these to work. I have been able to get the image creation part to work but am can not get the detector to work. I get the following errors: Do these errors relate to ros in anyway? The markerlessdetector.cpp seemed to compile ok.
