Thanks for the interesting solution. We took a slightly different approach, please see my answer.

My package is building a Python module using SWIG and cmake. It is a pure cmake package, using the <build_type>cmake</build_type> tag in package.xml. The build succeeds, and the PATH and CMAKE_PREFIX_PATH are updated, but PYTHONPATH is not. I can see the Python package installed to install/<package_dir>/lib/python3/dist-packages, so I know the Python package is being installed properly. --merge-install also correctly installs the package but does not update PYTHONPATH. The same package works properly with catkin_make_isolated.

Why is colcon not finding the Python package?

colcon-core version 0.7.1 colcon-cmake version 0.2.26

It turns out we had already solved this problem in a different project. See https://github.com/tesseract-robotics/tesser

It appears that moveit_msgs/CollisionObject uses the type byte which isn't discussed in the documentation for message types found at http://wiki.ros.org/msg . Is this an alias for uint8, int8, or some form of message structure?

I am the author of a communication package called Robot Raconteur that has been developed in parallel with ROS. It is an object-oriented approach that has dynamic object type negotiation with numerous features. I have just released an early testing version of RobotRaconteurROSBridge, a program that allows ROS services and topics to be exposed as Robot Raconteur services. Robot Raconteur has native MATLAB support, so through this bridge it is possible to access ROS topics and services from MATLAB.

EDIT: Robot Raconteur now has dramatically expanded language and platform support. The project website is http://robotraconteur.com . The new bridge is released as a github project:

Hello,

I am a little confused about using messages as data types within another message. Is this possible? How does the system resolve the message type? I noticed that the Header message does not require a package name.
