Hi, I'm trying to compile a library that make refference to

gazebo / gazebo / physics / PhysicsTypes.hh -->TrajectoryInfoPtr

The problem is that in Gazebo7 I don't seem to find that function.

In file included from /home/user/catkinws/src/mengegazebo/mengecommon/src/MengePlugin.cpp:8:0: /home/user/catkinws/src/mengegazebo/mengeactorsplugin/../mengecommon/include/MengePlugin.h:58:13: error: ‘TrajectoryInfoPtr’ in namespace ‘gazebo ::physics’ does not name a type
protected: physics::TrajectoryInfoPtr trajectoryInfo;

Is it elsewhere or was it created for GAzebo8. If so, is there any replacement in Gazebo7?

Thankyou.
