Activating Console in VS2008 Qt Integration Gui App

[sepp]

Hi,

i have a Win32 Qt Gui App build with VS2008 and the Qt VS Integration. Now i face crashes in Release mode, while Debug mode runs fine. Therefore i'd like to have messages in the console in release mode, but std::cout seems to be indirected into nowhere... I assume i have to state

CONFIG += console

somewhere, but where? I'm building inside VS2008...

Thanks for any help,

Sebastian

Try including the following header:

#include <QtDebug>

And then you can place debug statements like the following:

qDebug() << "Some out string";

Which uses the std::cout stream insertion format. The output will show up in the Visual Studio output window - no need for console.

qDebug() << "Some out string";
...

Thanks. But i need debug messages in release mode, when my App is running outside VS2008 (and therefore, there is no VS outout window)...

The config += console needs to go in your .pro file

Well, basically, i don't have a .pro file, because i used Qt Visual Studio Integration from the scratch...

I did the following test now which is like my approach:

- created a Qt Application in VS 2008 by the Qt Visual Studio integration
- created a basic .pro file from within VS 2008
- added CONFIG+= console
- closed my VS2008 .sln file and opened the .pro file in VS 2008

Well, besides that rcc fires an error now, i have the /SUBSYSTEM:CONSOLE in my linker switches now, but this is not what i want, because it makes my App to a console application.

Hmm. Seems to be difficult. From gtkmm i know that it is possible to have a Win32 Gui application with console i/o....

Then I don't think this has anything to do with Qt.
See the Visual Studio documentation on how to open a debugging console.

You're right. The link below solved the problem for me, in case anybody else here needs the same (Win Gui App with console):
