Hi,

I am trying to use a rosbuild based explorer package in ROS Indigo. During compilation it gives the following error:

fatal error: tf2/LinearMath/btVector3.h: No such file or directory
#include <tf2/LinearMath/btVector3.h>

I searched for the file but it was not present. Is there an alternative libraries in Indigo or higher versions of ROS or how should I install this library?

Thanks.
