Cannot retrieve debugging output in Qt Creator

In Qt Creator on Windows, qDebug() statements don't work, and the following message appears in the output window:

Cannot retrieve debugging output.

How can it be fixed?

Solution

  • This problem can show up if more than one instance of Qt Creator is active. To fix the issue, simply close all the other instances of Qt Creator and it should work.
