Hi everyone,

Well, i am trying to launch gazebo simulator on my system along with an object of Kuka Youbot in it. The "emptyworld" command seems to be working fine and the Gazebo launches successfully. the error occurs when i try to introduce a object in it, but typing the following commands:
1. roscore in one TW 2. roslaunch youbotdescription youbotarmdescription.launch in another TW and 3. roslaunch youbotdescription youbotarm_publisher.launch in an other TW

The first two commands seems to be working fine, that is the process runs successfully, but as soon as i run the third command in a TW, the gazebo runs successfully for about 5 seconds and the process dies automatically closing the Gazebo simulator and throws the following error:

"Main simulation loop failed /home/youbot/rosstacks/simulatorgazebo/gazebo/build/gazebo/server/controllers/ControllerFactory.cc:99 : Exception: Failed to load libgazeboroscontrollermanager.so: libgazeboroscontrollermanager.so: cannot open shared object file: No such file or directory

Service call failed: transport error completing service call: unable to receive data from sender, check sender's logs for details spawning success None [gazebo-2] process has died [pid 2498, exit code -11]. log files: /home/youbot/.ros/log/e142418c-136d-11e1-ad57-002682c60600/gazebo-2.log [youbotgazebomodel-3] process has finished cleanly. log file: /home/youbot/.ros/log/e142418c-136d-11e1-ad57-002682c60600/youbotgazebomodel-3.log"

I have no clue how to proceed with this, so, please help me with this issue. Thank you in advance....
