I currently have a terribly annoying problem while developing programs using Qt and Qt Creator. Whenever I try using qDebug()
with a QCoreApplication
or QApplication
instantiated before using qDebug()
, there isn't any output, whether I run the program in Qt Creator or from a normal shell(I'm using Fedora Linux btw). For example, even the following simple code fails:
int main(int argc, char *argv[])
{
QCoreApplication a(argc, argv);
qDebug() << "TestOutput!" << endl;
}
Does anybody know what to do about this problem? Thanks in advance, Marius
For better formatting, I add this new solution, marius still found it himself in this bugzilla.
Edit ~/.config/QtProject/qtlogging.ini
and add:
[Rules]
*.debug=true
qt.qpa.input*.debug=false
The last line is to disable spammy debug logging for moved mouse
messages.
