ROS SubscriberOptions problem in tutorial code

edit

Hi there,

following the tutorials (up to project structure) I ran into the following error:

[Err] [Model.cc:1256] Exception occured in the Load function of plugin with name[velodyne_control] and filename[/home/cdfghglz/WS/gazebo/plugins/velodyne/build/libvelodyne_plugin.so]. This plugin will not run.

I suspect the following to be the culprit:

Also it seems like the ros/subscribe_options.h is not being used. Any ideas what might cause this?

Thanks!
