Я пытаюсь создать небольшой проект ROS C++ (http://wiki.ros.org/loam_continuous) на ubuntu. Похоже, я не полностью понимаю принцип ros/rosmake или catkin. Во-первых, я не совсем понимаю, о чем идет речь в домашнем каталоге. Я создал папку carkin_ws в своем домашнем каталоге в соответствии с одним из обучающих программ для начинающих и поместил 4 файла cpp в ./src/loam_continuous/ , когда я запустил rosmake, он дает мне следующее сообщение, которое я не понимаю.проект C++ с использованием rosmake (kinetic on ubuntu 16.04)

когда я взглянуть на лог-файл содержит только это:

make: *** [all] Error 1
Я попытался запустить rosmake с Судом, но это, кажется, не опознает команду, когда я использование sudo. Может ли кто-нибудь указать мне на возможное решение, пожалуйста?
