I wish to learn ros and I started by doing the tutorials available on .

But in the "Writing a Simple Service and Client" tutorial, when it say to modify the file ~/catkin_ws/src/beginner_tutorials/CMakeLists.txt. I modified the secure file that is in ~/catkin_ws/src using sudo gedit CMakeLists. Before that, it worked but now I have a mistake when I do catkin_make.

CMake Error at /opt/ros/kinetic/share/genmsg/cmake/genmsg-extras.cmake:94 (message): add_message_files() directory not found: /home/audensiel/catkin_ws/src/msg

Call Stack (most recent call first): CMakeLists.txt:9 (add_message_files)

-- Configuring incomplete, errors occurred! See also "/home/audensiel/catkin_ws/build/CMakeFiles/CMakeOutput.log". See also "/home/audensiel/catkin_ws/build/CMakeFiles/CMakeError.log". Invoking "cmake" failed

When I remove all files and folders and I restart at the beginning (the tutorials), and i created mkdir -p ~/catkin_ws/src ... The file I modified previously is always the same. I think this is my problem, so if someone can give me the contents of this file or tell me how to retrieve the original.

Thank for your help.
