Strange compilation errors when I use Maemo5 specific Qt classes .. !

Hey guys .. I recently tried to use some Maemo5 specific classes (e.g. QMaemo5ListPickSelector, etc ..), and I'm getting some strange compile time errors ..

Here is a small code I was trying out:

Code:

---

QMaemo5ValueButton *x = new QMaemo5ValueButton("Hello");
    QStandardItemModel model (10,2);
    int i,j,k;
    for(j=0;j<=1;j++)
    {
        k=0;
        for(i=0;i<=9;i++)
        {
            QStandardItem *item = new QStandardItem(QString("%0").arg(k));
            k+=5;
            model.setItem(i,j,item);
        }
    }
    x->setValueLayout(QMaemo5ValueButton::ValueBesideText);
    QMaemo5ListPickSelector *sel = new QMaemo5ListPickSelector();
    sel->setModel(&model);
 
    x->setPickSelector(sel);
 
    QHBoxLayout *hbox = new QHBoxLayout();
    hbox->addWidget(x);
 
    QVBoxLayout *vbox = new QVBoxLayout();
    vbox->addLayout(hbox);
    vbox->addWidget(canvas);
 
    scrollArea->setLayout(vbox);
 
    setCentralWidget(scrollArea);

And this is the error I get:

And this is the same error in more detail:

I have installed the complete Nokia Qt SDK, and that is what is being used here as well ... The Maemo5 specific libraries are only 'seen' when I select 'Maemo' as the output device ..

Anyone know how can I fix these errors .. ?

I had a hard time configuring Qt Creator the first time round as well, and I really dont want to have to all kinds of un/re-installs all over again :(
