Revision history [back]

The problem is the include path order allows it to get the underlay, this is what it looks like on my machine:

/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/cc
-Drcl_interfaces__rosidl_typesupport_introspection_c__pyext_EXPORTS
-I/Users/william/ament_test/build/rcl_interfaces/rosidl_typesupport_c
-I/Users/william/ament_test/build/rcl_interfaces/rosidl_typesupport_introspection_c
-I/Users/william/ros2_ws/install/include  <-- this has the old header
-I/Users/william/ament_test/build/rcl_interfaces/rosidl_generator_c  <-- this has the new header
-I/Users/william/ament_test/build/rcl_interfaces/rosidl_generator_py
-I/usr/local/Cellar/python3/3.6.3/Frameworks/Python.framework/Versions/3.6/include/python3.6m

Please open an issue on the https://github.com/ros2/rcl_interfaces/issues repository and reference this question. It might end up needing to be fixed in rosidl instead, but that's the right place for now.
