Undefined symbol while using QDeclarativeView on Maemo

[a.v.mich]

Hi, while trying QML on Nokia N900, I have recieved this error:
/opt/usr/bin/ID3Editor: symbol lookup error: /opt/usr/bin/ID3Editor: undefined symbol: _ZN16QDeclarativeView6engineEv.

Following code:

@ _qmlViewer = new QDeclarativeView(0);

_qmlContext = _qmlViewer->engine()->rootContext();
_qmlContext->setContextProperty("systemModel", _systemModel);

_qmlViewer->setSource(QUrl("qrc:/qml/qml/ID3Editor.qml"));@

The same thing while calling rootContext() directly from QDeclarativeView. What can I do now? Only wait for the PR1.3?

We run QML on N900 often, double check if you are running your app with Qt 4.7 (the one in /opt/qt4-maemo5/) and not Qt 4.6 (the one in /usr/lib).

Also, check if there's an update for Qt on your N900. How did you build it? Scratchbox, Nokia Qt SDK?

EDIT: Qt 4.7 packages: libqt4-experimental-* (for the sake of completeness :-))

Did you tried setContextProperty?
QDeclarativeView with QML without setContextProperty works excelent.

Yes. Just tested again here, working nicely.

This kind of error used to happen when the binary was created with a different version than the one installed on N900, due to internal changes in QtDeclarative during the development of Qt 4.7.
