I try to use Qt with CLion. My problem is that qDebug() doesn't print anything, but qInfo(), qWarning(), qCritical() and qFatal() works well. Here is my example code : 

#include <QCoreApplication>
#include <QDebug>

int main(int argc, char *argv[]) {
    QCoreApplication a(argc, argv);

    qDebug() << "This will not appear";
    qInfo() << "This will appear";
    qWarning() << "This will appear too";
    qCritical() << "This will appear too";

    return a.exec();
}

Specs :

  • Qt : 5.5.1
  • GCC : 5.3.1 (64bits)
  • CMake : 3.3.2
  • CLion : 1.2.2

  • Please try including `` instead of ``, and try once again. Reference: http://doc.qt.io/qt-5/qtglobal.html#qDebug – Andrejs Cainikovs Dec 18 '15 at 12:29
  • I've rebuild the whole project after including `` instead of `` but it doesn't resolve the problem. – Hello Dec 18 '15 at 12:35

    I'm on Fedora 23 (4.2.6-301.fc23.x86_64). I've installed the same config on a Windows and it works. I think there is a problem with linux libraries. Maybe I haven't installed Qt properly on Fedora. – Hello Dec 18 '15 at 15:02

Fixed by editing the ~/.config/QtProject/qtlogging.ini file as follows :

[Rules]
*.debug=true
