I was trying to build the laser_proc repo for ros2 found here , but I am getting these errors. However it used to build properly until a couple days ago, I am guessing before this PR was merged : https://github.com/ros2/rclcpp/pull/4.. . because the errors pertain to changes made in this PR, however when I include rclcpp header file and use parameters in other codes it builds and works fine, for example talker code from demo_nodes_cpp works fine with parameters callbacks and everything, so what is going wrong in this laser_proc package?

The CMake code of that package sets the compiler flag -std=c++11. If you are using the current ROS 2 code base you will need C++ 14.
