Hi , Edit ros_service_examples/CMakeLists.txt downloaded from repo here . Add two lines in the end of CMakeList.txt add_dependencies(mp3_inventory ros_service_examples_gencpp) add_dependencies(mp3_controller ros_service_examples_gencpp) It works fine in ROS Lunar .

@xiongdemao You should create a catkin workspace with sub directory src first . Something examples is like catkin_ws |-devel └src 　　└ros_service_examples Please follow ROS tutorial to create workspace and download...
