Hello,

I am trying to update my package pi_tracker to Hydro without switching to catkin (I know, I know). Everything builds fine with my Groovy-compatible manifest and CMakeList.txt file except when trying to generate a new message type.

My message type is called Skeleton.msg in my msg directory and it is defined as follows:

Header header
int32 user_id
string[] name
float32[] confidence
geometry_msgs/Vector3[] position
geometry_msgs/Quaternion[] orientation

The error I get when running rosmake is:

roslib.msgs.MsgSpecException: Cannot load type 'geometry_msgs/Vector3'.  Perhaps the package is missing a dependency.

However I do have the following line in manifest.xml:

<depend package="geometry_msgs"/>

And I can run:

$ rosmsg show geometry_msgs/Vector3
float64 x
float64 y
float64 z

So what am I missing?

Thanks!
patrick

P.S. The full error message is shown below:
