Hello all, I am new comer in ROS. I just finished the tutorial and made Publisher and Subscriber node. Here is a question. Can I subscribe messages from normal C++ code without ROS? For instance, I want to subscribe "chatter" topic in the tutorial with normal socket connection (without ROS subscribe method). If possible, how can I do it? Any information is welcome. Thanks in advance. Keisuke --------------------------------- 2010 FIFA World Cup News [Yahoo!Sports/sportsnavi]
