I want to use the example in this tutorial and register feedback and active callbacks to pass to the boost::bind. However, i have trouble finding the proper syntax/way to register them.

Well, basically you just have to repeat the syntax given for the doneCB. As far as i understood, you need the binder because you cannot use the () operator to indicate if your function has inputs.

The first parameter references your function, the second one to which object the function belongs to. Afterwards, you just need parameters if you have inputs.

Here's n' example how i implemented this. ac.sendGoal(goal, boost::bind(&MyNode::doneCb, this, _1, _2), boost::bind(&MyNode::activeCB,this), boost::bind(&JacoClient::feedbackCb, this, _1));

If you want more details, you can check out the boost documentation ( it's quite good documented).
