[ament_cppcheck] Unable to resolve macro definitions from includes #116
Description
With the latest release of cppcheck (v1.86), tests have started failing in rclcpp with the following error message (or very similar):
There is an unknown macro here somewhere. Configuration is required. If RCLCPP_SMART_PTR_DEFINITIONS is a macro then please configure it.
Example build: https://ci.ros2.org/view/All/job/test_ci_osx/118/
I don't believe this is an error in rclcpp itself, but with how cppcheck is invoked.
If cppcheck is invoked with the -I option, passing the include directory, then the error goes away.
E.g.
cppcheck -I rclcpp/rclcpp/include rclcpp/rclcpp/include/rclcpp/client.hpp
Documentation for the -I option:
-I <dir> Give path to search for include files. Give several -I
parameters to give several paths. First given path is
searched for contained header files first. If paths are
relative to source files, this is not needed.
