I am following this tutorial on action lib:Writing a Simple Action Server using the Execute Callback But after i build the package and than run the fibonacci_server node i'm not getting any ROS_INFO as shown in the tutorial like this: [ INFO] 1250790662.410962000: Started node [/fibonacci], pid [29267], bound on [aqy], xmlrpc port [39746], tcpros port [49573], logging to [~/ros/ros/log/fibonacci_29267.log], using [real] time When i checked the rqt_graph I'm getting: image description When i run rostopic list -v, i'm getting:

My CmakeLists.txt file is exactly as instructed but after i run the command line: rosrun actionlib_tutorials fibonacci_sver what i get is nothing.

Everything is all right here. To get the image shown in the tutorial (which was taken from rxgraph, an older alternative to rqt_graph:

  1. change visualization in the drop down to Nodes/Topics (all)
  2. uncheck the Actions check box, as well as the Dead sinks and Leaf topics

But I must say I am unsure why the ROS_INFO output does not appear. Maybe this has been removed from rosrun?
