For now, you might need to do something like viewer.engine()->addImportPath(QString("/opt/qtm11/imports"));

I can't get my Qt Mobility working application to work on an actual N900. I've:

Created a blank Qt Quick application in the latest Qt SDK
Uncommented the lines about mobility in the .pro file
Added import QtMobility.sensors 1.1 at the top of my script
Added an Accelerometer component
Run apt-get install libqtm-11-declarative

This works in the simulator, and everything's works as I rotate the screen. So I deployed on to my N900 and I get "module "QtMobility.sensors" is not installed".

I've tried adding the line above to my main.cpp:

Code:

int main(int argc, char *argv[])
{
    QApplication app(argc, argv);

    QmlApplicationViewer viewer;
    viewer.setOrientation(QmlApplicationViewer::ScreenOrientationLockLandscape);
    viewer.engine()->addImportPath(QString("/opt/qtm11/imports"));
    viewer.setMainQmlFile(QLatin1String("qml/attitude/main.qml"));
    viewer.showExpanded();

    return app.exec();
}

But now it doesn't compile: invalid use of incomplete type 'struct QDeclarativeEngine'.

Any ideas?

In Qt Creator, the fact that you don't get autocompletions is a good hint you need to include the header for that class.

Thanks to Ville, Arek & Thomas, it was indeed missing:

Code:

#include <QtDeclarative>

What is the effect of having the setImports line on Symbian? Or MeeGo? Will it error or be ignored?

You mean addImportPath ? It works as a path, even if you add non-existent paths, no biggie as long as it *does* find the things it's looking for (the function itself is part of Qt, so whether it's Symbian, Maemo, Desktop... doesn't matter). And I do plan on fixing it (as in making it unnecessary), but it depends on upstream.

There is a bug in Qt Mobility 1.1.1 which prevents audio playback using gstreamer. It occurs on desktop Linux and on Maemo5. The bug is fixed in the 1.1 git branch.

Would it be possible to get that version into Extras-devel? It's even enough to replace plugins/mediaservice/libqgstengine.so. Having no audio playback is (for some apps) a major blocker.

The command you need is

Code:

apt-get install libqtm-11*

Good news everyone, I got 1.1.2 with a few extra Maemo fixes in extras-devel, all interested parties, please try it out !

Note: Since I included the extra Maemo patches I had to go a little ahead of the 1.1.2 tag, so the reported version is actually 1.1.3, but don't let that confuse you, it really is 1.1.2 under the hood.

Can you check if the 1.1.2+ I uploaded fixed this ?
