QT 5.0 QDebug compilation error

Question

I am having trouble compiling my code with QDebug, but i really need it.

#include 
#include 
int main(int argc, char          


        

Answer 1

For version 5.15 of Qt following worked for me,

add include file,

#include <QDebug>

and use,

qDebug() << "Your debug message.";

Answer 2

Try this:

qDebug() << "hello";

Answer 3

The problem here is that QDebug does not have a default constructor. QDebug() << "hello"; would work if it did have one.

These are the available constructors:

QDebug(QIODevice* device);
QDebug(QString* string);
QDebug(QtMsgType type);
// and the copy constructor of course.
