I tried to follow the tutorial for the pid joint. With ROS groovy and Gazebo 1.3. If I add the build dir to the ROS_PACKAGE_PATH and run using: rosrun gazebo gazebo -u ../ It can find the plugin..

Error [Plugin.hh:126] Failed to load plugin

I also tried it using the standalone Gazebo 1.5. Then the box is spawned but Gazebo crashes as I push the play button.

For the first issue using gazebo 1.3 most probably you are missing the GAZEBO PATHS to the plugin.

Here is an example how to add yout package plugin library:

$ export GAZEBO_PLUGIN_PATH=/<path>/your_package/lib:${GAZEBO_PLUGIN_PATH}

For the second issue when you run your code with gazebo 1.5, this might appear because your code could be built against the gazebo 1.3 libraries from groovy, that's why you get that error when you run the plugin.

To avoid this when you build your package you should comment out <depend package="gazebo"/> line from your manifest.xml file. Afterwards in the CMakeLists.txt file add the following lines to link against yout gazebo 1.5 libraries:

## link to gazebo libraries 
include (FindPkgConfig)
  pkg_check_modules(GAZEBO gazebo)

Cheers, Andrei

Thanks for your response! The build dir with the is both in the gazebo and ros path. But that does not help. I builded these not as a ros package, will try that later.
