how to echo custom-defined message remotely?
There are two machines, A and B, connected via Ethernet cable, and their connections are established. One of the ROS package implemented at the machine A has custom messages, and I would like it to be read at the machine B by using the command rostopic echo <topic-name>
.
When I typed the command, I got the following error message.
ERROR: Cannot load message class for [<message-name>]. Are your messages built?
Does this mean that I have to build the custom message at the machine B as well? If so, how?
