Hi, I want to create a custom msg file and use it in arduino. I followed official rosserial tutorial for that. I created a package and a msg file. I can see the message file using "rosmsg show" command. So the custom message successfuly created. The official tutorial link is below. The name of the pacakge which my custom msg file is "imugpsservo". I saw this command for generating header files to inside of the roslib "rosrun rosserialclient makelibrary.py ~/Arduino/libraries imugps_servo". But when i run this command there is no any output in terminal and the header files of my msg file is not created.
