failed to execute: roslaunch turtlebot_bringup kinect.launch [closed]

edit

Hi all,

I just started using turtlebot and I was following the instructions in the tutorials. Everything is fine until this step:

http://ros.org/wiki/turtlebot/Tutorials/Looking%20at%20Camera%20Data

when I try to execute 'roslaunch turtlebot_bringup kinect.launch', a lot of failures comes, which are similar to the following messages:

"[ERROR] [1339737590.517331183]: Failed to load nodelet [/kinect_laser_narrow] of type [pointcloud_to_laserscan/CloudToScan]: Failed to load library /opt/ros/electric/stacks/turtlebot/pointcloud_to_laserscan/lib/libcloud_to_scan.so. Make sure that you are calling the PLUGINLIB_REGISTER_CLASS macro in the library code, and that names are consistent between this macro and your XML. Error string: Cannot load library: /opt/ros/electric/stacks/perception_pcl/pcl/lib/libpcl_visualization.so.1.1: symbol __cxa_pure_virtual, version libmysqlclient_16 not defined in file libmysqlclient.so.16 with link time reference I am unsure what is going on... I tried running it on the turtlebot laptop and the workstation with ssh -X, they both gave me those errors.

I got Ubuntu 10.04.4, ROS electric.

Thanks in advance! Midnight
