custom msg in pub/sub node

Question

Want to implement user defined msg in nodes I edited CMakeLists.txt to include rosbuild_genmsg().

In the publisher/subscriber node, do I have to include it like in the case of std_msg? (i.e. #include "msg/custom_msg.h" or something?)

Will this correspond to the following change: ros::Publisher chatter_pub = n.advertise**msg::custom_msg**("chatter", 1000);

Further, I want to create a subscriber node, and publish messages to it manually, should the corresponding callback method be modified as:

void chatterCallback(const msg::custom_msg::ConstPtr& msg) { ROS_INFO("I heard: [%s]", msg->data.c_str()); }

Thanks a lot, really appreciate your help.

What you use as msg should be the package name.

Otherwise it should work.
