I try to catkin_make packages but it fais:

CMake Error at /opt/ros/groovy/share/genmsg/cmake/genmsg-extras.cmake:64 (message) : add_message_files() directory not found: /home/user/catkin_ws/src/msg

I can't understand why it tries to find msg files in src/msg.

catkin_ws/src/beginner_tutorials/CMakeList.txt

project(beginner_tutorials)

find_package(catkin REQUIRED PACKAGES roscpp rospy std_msgs message_generation)

Can you please be more clear and explain more about what you are doing. Can you tell me if you sourced the file and can you output you ROS path.

ROS_ROOT=/opt/ros/groovy/share/ros, I'm studying tutorial "Writing a Simple Publisher and Subscriber (C++)" and try to make packages. Previously I created msg and srv files in corresponding paths in beginner_tutorial.

Could you show your CMake file ?

Done, Lucile

Did you generate your catkin workspace with catkin_init_workspace ? If so, your catkin_ws/src/CMakeLists.txt should be totally different. Anyway, you ask for Num.msg and AddTwoInts.srv in src folder and I think that's why cmake looks for them in src/msg folder.

Yes, but I accidentally delete CMakeLists.txt in catkin_ws/src and tried to generate it using catkin_init_workspace once again, and it created that file. I can't find an example of necessary file to copy in catkin_ws/src.

just do another catkin_workspace then to run the publisher example.

Not sure which tutorial you were referring to, but assuming it was one of basic tutorials listed here:

directory not found: /home/user/catkin_ws/src/msg

No tutorial instructs you to create a msg directory under src directory. Instead, like this section, you're supposed to create INSIDE of a beginner_tutorials package.

catkin_ws/src/beginner_tutorials/CMakeList.txt

So yes, CMakeLists.txt you were editing is for beginner_tutorials package, and because the add_message_files macro is in there, it should make sense to you to have msg in the package too.

The problem was in the CMakeLists.txt in the root catkin workspace path. If you remove this file, the command "catkin_init_workspace" will create a new one, but it will be different and wrong. So I copied it from Beginner Tutorial github repository. :) But, notably, the command catkin_init_workspace works strange in this situation.
