Hi, I have been wanting to get various Gazebo plugins working with ROS using SDF format, starting with Differential Drive plugin. I had some small success getting Twist messages to change joint states, but now I want to get odometry working. I have just pieced together what I could from erraticgazeboplugins and the DRCSim plugins.


this->transformBroadcaster = new tf::TransformBroadcaster();

Any time I want to declare a TransformBroadcaster type I get this error:

gazebo: symbol lookup error:

/home/thelegace/fuerteworkspace/alesrobot/ales_msgs/lib/ undefined symbol: _ZN2tf20TransformBroadcasterC1Ev

If I comment out the transform broadcaster instantiation my plugin loads fine. The pioneer2dx model file.

Please let know if there any issue with the code or anything else that I am doing.

This seems to be a a linker error, I think. Are you linking the tf library in CMakeLists.txt?

Undefined symbol errors usually indicates that a library cannot be found, or an incorrect library is used.

In your case I believe Gazebo will have to find a library for tf. Check your LD_LIBRARY_PATH environment variable.
