qDebug() outputs only to QtCreator panel, but not to the cmd window

nulluse

Throughtout the project there are a few qDebug() calls that dump tons of output to the Application Output panel. However when I run the same program on the Windows command window there is no output whatsoever. What am I doing wrong?

Hi, you're doing nothing wrong, no output in the CMD window is the expected behavior. Instead, you can download DebugView it can show the qDebug() calls.

You cannot be serious.

It may be the expected default behaviour, but I'm pretty sure its changeable.

If I remember correctly (don't have a Windows host handy), you need to add:

CONFIG += console

to your build (eg *.pro file) if you want such output in release builds.

See, for example, this old thread: qDebug() under Windows.

Cheers.
