Qt qDebug() doesn't work in Windows shell

Question

I am using a qDebug() of Qt Framework for printf something on the screen. It works just fine when I run application from Qt Creator, but when I try to execute it from Windows cmd it shows nothing. Why that happens?

Answer 1

You have to add

CONFIG += console

to your projects .pro file and do not forget to clean and build (rebuild) your project.

Thanks. It works. I think I even tried this before, but didn't clean and build full project. – Gallaway

I've add recommendation to clean and build to answer. – Shifrah

Answer 2

Run your application with

application.exe > log.txt 2>&1

It redirects stderr to stdout and stdout to a file.
