I wanted to use the "IntelROSProject" and followed the guidelines. But upon running the command "catkin_make", I got an error saying that cmake failed. Reason was that he was missing kobuki_msgs, but the github page for the package that depends on it (ros_moving_object) says that it should be part of the full desktop install.

And in fact, I could find the kobuki_msgs... Why aren't they part anymore of the full desktop install?

Oh, okay, my bad. Thanks for your hint! But the way they listeted the needed packages, it seemed to me kobuki is also pa

I am in the tutorial at CreateMsgAndSrv and got stuck at chapter 3. Running the command

$ rosmsg show beginner_tutorials/Num

got me the following

Unable to load msg [beginner_tutorials/Num]: Cannot locate message [unint8] in package [beginner_tutorials] with paths [['/home/aha/catkin_ws/src/beginner_tutorials/msg', '/home/aha/catkin_ws/devel/share/beginner_tutorials/msg']]

and searching the web for a solution I stumbled upon a thread where someone had somewhat the same problem and said that he made a

catkin_make install

after the changes at the package.xml and CMakeLists.txt which I did not. But it made sense so I ran the command and then got the following error during the install process

CMake Error at /home/aha/catkin_ws/build/beginner_tutorials/cmake/beginner_tutorials-genmsg.cmake:3    (message):                                                                                             Could not find messages which                                                                          '/home/aha/catkin_ws/src/beginner_tutorials/msg/Num.msg' depends on.                                    Did you forget to specify generate_messages(DEPENDENCIES ...)?

But I followed the tutorial as it is written and did not forget to specify/uncomment "generate_messages". As I am a Newbie, I am kind of lost now and do not really know how to proceed. Can someone help me out?

System is Ubuntu 16.04 LTS, the ROS-Version is Kinetic and I added

source /opt/ros/kinetic/setup.bash

and

source ~/catkin_ws/devel/setup.bash

to my ~/.bashrc. Hope this sufficient information for the beginning...
