How to enable qDebug and qInfo message in Virtualbox frontend ?

Hi,

qDebug and qInfo messages are disabled in VirtualBox frontend and I didn't find how to enable them.

This simple Qt piece of code :

Code: Select all

#include <QDebug>

int main()
{
    qDebug("qDebug");
    qInfo("qInfo");
    qWarning("qWarning");
    qCritical("qCritical");
}
outputs this on stderr :

Code: Select all

qDebug
qInfo
qWarning
qCritical
But VirtualBox frontend only outputs :

Code: Select all

qWarning
qCritical
Even if I enable debug build with

Code: Select all

./configure -d
qDebug and qInfo remain disabled.

How can I enable them ?

Regards.
