Hi everyone,

I have successfully created few ROS2 nodes (one for a publisher with customer message, the custom message one, one responsible for debugging, one for the subscriber).

I have repeated the exact same steps in order to create some other packages. However, the last one that I created returns "No executable found".

I am developing using python3.

I am pretty sure that package.xml,, setup.cfg and the actual node class are fine.

Also, no issues when running rosdep, all fine with colcon build, and I have installed everything with . install/setup.bash.

What could the problem be? Any idea?

Thanks in advance, G.

Do you see the executable when you run?

ros2 pkg executables <pkg_name>

I believe that the error was caused by wrong action on my side.. I built and installed without realizing at the wrong level of the project tree.. that was enough to mess things up ...

In my case I had to add this command to my CMakeLists.txt script just bellow the call to add_executable(..) and ament_target_dependencies(...).


After building:

cd ~/ros2_ws
colcon build

And sourcing:

source install/setup.bash

and finally:

ros2 run [package_name] [executable_name]

This solved the issue.
