Hi guys,

I am new in Ubuntu and ROS. The system I am using is ROS Fuerte. It is running in the Ubuntu 12.04 Lts.

When I try to open the openni_tracker I get the following error message:

"[rospack] Error: stack / package openni_tracker not found."

Some months - doing the same procedures - I could normally run the openni_tracker. What might be happening?

It looks like the openni_tracker is not in your ROS package path. Did you source the correct setup.bash file (The one that you used at the time when it worked)?

michikarg thanks for the help. The openni_tracker had been uninstalled. To solve the problem I just installed it. But now when I try to run the openni_tracker I get the following message: [ERROR] [1357217210.034954916]: Find user generator failed: This operation is invalid!
