these answers did not help me.
in my workspace, I have my custom message stereo_msgs/RectifiedImage.msg I want to publish that.
when I do rostopic list, I can see "/mycustomtopic"
but when I do rostopic echo, "ERROR: Cannot load message class for [stereo_msgs/RectifiedImage]. Are your messages built?"
my_msg_pub_ = nh.advertise<stereo_msgs::rectifiedimage>("mycustomtopic", 1);
this is in my main function
and in my callback function (i am subscring to other message type),
my_msg_pub_.publish(myimage);
