Custom Message Creation

I've followed the ros tutorial for creating a custom message, but I'm unsure as to where to put it. Does it go in ros_workspace/package/msg/CustomMessage.msg? Or does it go into opt/ros/electric/stacks? If so, where exactly?

I'm making a node to publish a Vehicle.msg message filled by the Joy driver. I'm using the turtle_teleop_joy tutorial as my base. I need the custom message to define the axes.

Your first suggestion is correct. You put it in the msg directory of your message package. Make sure you then update the CMakeLists.txt to add the rosbuild_genmsg() option. Also, be sure to make any package using this message to depend on your message package (unless your messages are located in the same package as your node).

Thanks! I thought this was the source of my error, but I see it successfully generated the msg_gen folder and files in the package folder.

Also if other packages need to use the custom message from package A, make sure the manifest of package A exports the include cflags.

@Ivan Dryanovski: I believe the CFLAGS export is provided automatically, now.
