My idea is that this error occurs related with urdf , urdf_parser_plugin and liburdfdom-tools .. I searched that liburdfdom-tools is old and not related with ROS but I have been installed that and I couldnt fix it.. there is the time important for develop the robot for my Thesis lead me please.. what can I do for fix it ? by the way I use ROS / indigo
