Hi guys,I was trying to get the "Hello World" program up and running with an Aruino Mega board. I finished the entire thing but got stuck on compiling the actual example code. http://www.ros.org/wiki/avr_bridge/Tutorials/Hello%20World#main.cpp It has an include which is not in the downloadable eclipse project: #include "avrRos/Ros.h" //main avrRos library #include "avrRos/String.h" //std_msg/String library I couldn't find the String.h file on the git hub either: https://github.com/rutgers/avr_bridge Thanks for any help --
