Answering to myself, for the record:
I found where the problem laid:
I was using QGuiApplication in my main for the Qt5 port, but since
QtWebKitWidgets is QtWidgets based, a QApplication is needed. I
realized this when I tried to create a QWebView to see if that was
needed. That triggered an assert indicating that QtWebKitWidgets
requires a QApplication.
Now my application is ported and working. It will need tweaks here and
there, but the functionality is there.
The good news is that most of the components I had to add to have my
application look "native" in Harmattan are not needed in Sailfish OS,
and the QML files are much simpler.
The C++ part needed a few tweaks to build with Qt5, but not as many as
I expected. I should be able to build with both Qt5 and Qt4 (for
Harmattan and Maemo5) without problems.
Best regards,
Luciano
