Hi Guys,

I just dual booted Xubuntu 12.04 along side my existing Ubuntu 10.10 install, and proceeded to to a fresh install of fuerte (on 12.04) by following the instructions on the install tutorial.

I then installed openni_kinect (which installs openni_tracker).

I have a Kinect attached (which works fine on 10.10/electric) and fired up the openni_tracker with the command "rosrun openni_tracker openni_tracker".

I get the following error:

"ERROR 1338827753.716401344: Find user generator failed: This operation is invalid!"

I am wondering if I didn't set up my environment properly, or if there is an xml file missing somewhere.

Please let me know if you have any ideas.

Thanks!

Kel

Hi,

I had the same error in a Ubuntu 12.04 LTS running in a MacBook Pro (with dual boot).

I am the third one that has found the same problem, so I have posted it here: http://answers.ros.org/question/36921/openni_tracker-timeout-error-in-fuerte-ubuntu-1204/

I hope we finally manage to solve it.

I had this problem. Every time I ran the openni_tracker node it threw a "Find user generator failed: This operation is invalid!"

How I solved it: Run the ./install.sh from your NITE download. I used NITE-Bin-Dev-Linux-x86-v1.5.2.21

Hope this helps!

I believe that this is an issue in Fuerte. I've created a bug report of the error.
