[ros-users] rosdep cannot resolve bluez

Fri May 7 19:20:38 UTC 2010

D,

when I step through turtle_tf_listener.py with pdb it fails after

-> rospy.wait_for_service('spawn')
(Pdb) zsh: illegal hardware instruction  pdb turtle_tf_listener.py
__name:=turtle_listener

and pdb exits with sigill

cheers, Felix
