Hi,

I tried to run a ros node in qtcreator (version 3.5.1). It works in debug mode, I can have breakpoints, see variables ... I was able to change option for CMAKE ... with option Debug. No problem I think here;

But I don't see where are the outputs (I have ROS_INFO lines in my ros file). I can see that it works when I do a "rostopic echo /rosout_agg" in another terminal. But it's difficult to see my debug messages with others messages which come in.

So my question is simple: where can I see the messages when I execute lines with ROS_INFO.

Thanks for help

qtcreator 3.5.1, ubuntu 14.04.3, ROS indigo

In Debug mode you should be able to see your info messages in Qt Application Output. I attached an image of my project in which you can see the output of a ROS_INFO line.

Hope this helps.

Hi Mario, Thanks but I don't have the same as you. I tried with part of your code, and it's the same. In Application Output, I get "Debugging starts" and after ... nothing. Except Debugging has finished when I stop the code (I publish in a topic every second). Is-it a bug ? Thanks.

I suggest few things: - make sure you start qt creator from terminal, after sourced your environment - make sure to uncheck the "run in terminal" checkbox in "project->run settings" - check cmake argument -DCMAKE_BUILD_TYPE=Debug - try to remove CMakeLists.txt.user in your catkin_ws and restart qt.

Hi, Thanks Stefan. But In Application Output I only have "Debugging starts" and "Debugging has finished". No output from ROS_INFO.

So the question is still there.

If you start your node from inside QtCreator (as opposed to attaching to a node you started externally), you should be able to see it's output in the "3 Application Output" Tab as visible on the bottom in this Screenshot from Wikipedia.
