When I try to build the client-server C++ tutorial with catkin_make it doesn't create any executables, I think I have everything else in order. I had followed every single step in the previous tutorials, the worspace is correctly configured, the CMakeLists.txt seems in order as the package.xml.

Here is the link to the tutorial.

And the output when I try to build and then execute.

viki@c3po:~$ cd ~/catkin_ws/

viki@c3po:~/catkin_ws$ catkin_make

viki@c3po:~$ rosrun beginner_tutorials add_two_ints_server

[rosrun] Couldn't find executable named add_two_ints_server below /home/viki/catkin_ws/src/beginner_tutorials

This is not enough information to be able to help you. Please edit your question to include a link to the tutorial you're following. Every command you're running and the exact console output, what's in your workspace, and any other relevant information to reproduce your problem.

Could you add your workspace environment variables ? You can have them with export | grep ROS

The output at the bottom tells you exactly what the problem is. The syntax of rosrun is rosrun PACKAGE EXECUTABLE [ARGS]. You are not providing an executable to rosrun.

Sorry I wrote that incorrectly, anyway when I write "rosrun begginer_tutorials add_two_ints_server" it says the same thing, add_two_ints_sever is the executable created when building add_two_ints_server.cpp, but the problem is that the executable is never created. Also there is no need of arguments

I edited the question so you can see the output when I write the correct command

Perhaps you are not adding an executable in your CMakeLists.txt.

Do you have this line in CMakeLists.txt: add_executable(executable_name source_file_name.cpp ?

Yes I do, as specified in the tutorial. CMakeFile.txt:add_executable(add_two_ints_server src/add_two_ints_server.cpp)

I couldn't find any answers, so I deleted the Ubuntu image with the ibraries of ROS preinstalled, downloaded another image of Ubuntu and then instaled the libraries and the packages of ROS manually. Now everything seems to work, maybe one of the packages wasn't installed in that image.
