Activating QML debugging ignored

[kuschky]

Hello,

I'm using Qt Creator 4.2.1 on Linux 64bit. In my Qt 5.4.0 project I enabled the Qml Debug support project/build/qmake settings and also under project/run/debugger settings

Sometime ago it was working for me but I'm not able to enable Qml Debugging. When starting the debug session the debugger log view gaves me the following information that Qml debugging settings are ignored. But it did not tell me why:

"QDeclarativeDebugServer: Ignoring "-qmljsdebugger=port:43357,block,services:DebugMessages,QmlDebugger,V8Debugger,QmlInspector". Debugging has not been enabled."

A view with netstat shows me that port 43357 is not opened.

Any idea why it's ignroed and how to enable the Qml debugging?

Thanks & best regards Michael

I checked the source and it seems that my Qt libraries are compiled without qml debug option enabled

    if (!QQmlEnginePrivate::qml_debugging_enabled) {
        qWarning() << QString(QLatin1String(
                          "QML Debugger: Ignoring \"-qmljsdebugger=%1\". "
                          "Debugging has not been enabled.")).arg(
                          appD->qmljsDebugArgumentsString());
        return;
    }
