I am trying to execute the turtle example following the steps in: http://www.ros.org/wiki/ROS/Tutorials/BuildingPackages When I come to the point of building packages for next tutorials it shows an error in my installed packages: # rosdep install turtle_teleop rxtools Failed to find rosdep libbluetooth-dev for package turtle_teleop Failed to find rosdep libx11-dev for package turtle_teleop ERROR: ABORTING: Rosdeps [u'libbluetooth-dev', u'libx11-dev'] could not be resolved Then, I installed them: # apt-get install libbluetooth-dev libx11-dev Reading package lists... Done Building dependency tree Reading state information... Done libbluetooth-dev is already the newest version. libx11-dev is already the newest version. 0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded. However, this does not make any change in building the packages. Can you help me to know how can I solve this problem? Kind regards, Renato. _________________________________________________________________ Hotmail: Trusted email with powerful SPAM protection. https://signup.live.com/signup.aspx?id=60969
