Circular Dependency - Matlab Simulink

edit

Hi all,

I'm trying out the Matlab Simulink Robotics Systems Toolbox and I'm getting a circular dependency error when I try and build. All I'm doing is subscribing to a sensor_msgs topic and then publishing the same message on a normal std_msgs topic. Even when I try and build just this ROS node on it's own with no other I get the error below. What's interesting is if I change the subscribed topic to a std_msgs/float32 for example it builds fine.

CMake Error at /media/sf_ADS/build/catkin_generated/order_packages.cmake:7 (message):
  Circular dependency in subset of packages:

  rosbag, rostest, sensor_msgs, topic_tools
Call Stack (most recent call first):

This is the CMakeLists.txt - is it correct?

and this is the package.xml

  <run_depend>roscpp</run_depend>
  <run_depend>sensor_msgs</run_depend>

</package>

I don't understand enough about this yet and can't interpret the log/error file well enough.

Any help would be much appreciated!

Thanks guys
