Upgrading from 4.6.3 to 4.7.1 on N8

sriky27

Hi,

I have developed an application on N8 using Qt 4.6.3. While it was running I have installed Qt 4.7.1 binaries on the phone, the application showed a weird behaviour. How should the application developer handle this kind of situation. Please advise.

What behavior??

sriky27, where do you find Qt 4.7.1 for N8?

Hello,

Once you download and install the 4.7.1 sdk for Symbian ("here":http://qt.nokia.com/downloads is the download page), you'll see the sis files there. "Here":http://doc.qt.nokia.com/4.7/install-symbian-installer.html are the instructions for installing on device. Does that work for you?

johnk, I suggest, this sis files will not be installed on Nokia N8.

bq. The problem is that Qt is pre-installed on S^3 devices and the Symbian Signed version of Qt that is available from the normal download channels (and released at the same time as the other platforms) does not have the necessary package flags to upgrade a Qt that is pre-installed on the device.
"http://labs.qt.nokia.com/2010/10/18/qt-4-7-for-symbian3-developer-version-available/":http://labs.qt.nokia.com/2010/10/18/qt-4-7-for-symbian3-developer-version-available/

And I see only Qt 4.7.0 developer version for N8

Hello Alexander,

Sorry I forgot about that important fact.

In fact, I'm looking for Qt4.6.3 library to be installed on my Windows Desktop, but seems all the download links from nokia has been updated to Qt 4.7, How could I create an application for N8 specifically then?

You can install Qt 4.7 on your Nokia N8.

Wenzheng

yes, but doesn't mean I can install Qt4.7 on the user's N8, which means if I'm using Qt4.7 to build an app the N8 users would not able to run it.. and that is not good.. :(

Qt 4.7 is available now for developers, will be available for users soon. As you're a developer, you can start creating your 4.7 based apps so they will be ready when the users devices receive the upgrade. :-)

You need to deploy your app packaged with the Nokia Smart Installer (aka Qt Smart installer). This will check the N8 when your app is being installed on a users phone. If the Qt libraries need to be updated, it will download and install the updates

see http://wiki.forum.nokia.com/index.php/Nokia_Smart_Installer_for_Symbian

:-)

maybe it's because of fixing threading problems on 4.7.1

SmartInstaller does not support Qt 4.7 now.

That's is correct, but when you deploy a Qt application you need to use the Smart Installer and that is how the libraries will be installed by the user to the device.

I'm not sure of the release date for qt.4.7 for Symbian ^3. Anybody?
