developing application for different symbian devices - qt

I need to develop applications for nokia devices running S60 3rd Edition, Feature Pack 1, S60 3rd Edition, Feature Pack 2 S60 5th Edition, Symbian^3 the documentations in nokia forums is not quite understandable. I understand that at present to develop applications for nokia device qt to be used. Now there are two versions of qt SDK 1.1.4 and qt SDK 1.1.2
Which should i download to develop applications for the all the three symbian platforms..?

I think you should stick to 1.1.2.
Qt SDK 1.1.4 contains only the latest targets for developing applications for a particular Symbian platform. The targets for Qt 4.6.3 for Symbian and Qt 4.7.3 for Symbian^3 and Symbian Anna have been removed from Qt SDK 1.1.4. To develop for these targets, use Qt SDK 1.1.2. Once you have installed Qt SDK 1.1.2, to enable use of the earlier targets and App TRK, don’t run the SDK update as this will remove the features you need.

Which version of qt is used on Blackberry 10.0 OS (momentics 1.0)?

I am curious about the qt version used on Blackberry 10 momemtics IDE. Can I use QT5 for blackberry 10 development ?
Directly from the documentation you can find here.
The current release of the BlackBerry 10 Gold NDK
[developer.blackberry.com] includes Qt 4.8 for both the simulator
target (x86) and device targets (arm) available for development.
Compared to the development for the PlayBook, Qt is integrated in the
BlackBerry 10 device firmware and so can be used by Qt applications as
shared libraries.
The page is quite detailed. Have a look at it.
However, Qt5 can still be considered. You can find more information on how to use this Qt version in this other page, which states:
Currently, Qt5 is neither included in the BlackBerry 10 device
software nor in the BlackBerry 10 SDK. However, Qt5 on BlackBerry 10
has reached a excellent level of quality and can be used for
developing and publishing applications to BlackBerry World.
BlackBerry 10 supplies only Qt 4 libraries.
You can use Qt 5 as long as you bundle your application with self-built Qt libraries.
Here you can find detailed information.

Mobile operating systems which can be targeted by Qt, QtQuick, QML and QtMobility

The number of mobile operating systems or platforms supporting QT based app development keeps growing. Not for all of them QT is the standard framework for building apps, therefore it seems the Qt support can be categorized as follows:
Qt and Qt based technologies (QML, QtQuick, QtMobility) are the recommended way for building mobile apps and part of the SDK.
Qt or a subset of Qt is supported as a secondary way of developing or porting apps, and there is support for a subset of QT APIs within the SDK.
Unofficial 3rd party or open source extensions enable development of Qt based apps for a platform.
Which mobile operating systems or SDKs do support development of apps using Qt in either of the above listed ways?
Mobile operating systems with full Qt support in the SDK:
Nokia Symbian OS: http://www.developer.nokia.com/Develop/Qt/. Since Nokia discontinued Symbian, Qt for Symbian is a community effort now.
Nokia N9 / MeeGo 1.2 Harmattan: Full Qt support.
Mer (community Meego fork) and Sailfish OS: Qt/QML are both supported.
Canonical's Ubuntu Phone uses the Ubuntu QML toolkit and Qt Creator for native application development.
Mobile operating systems supporting a subset of the QT APIs:
Blackberry 10 OS and SDK: The Blackberry 10 SDK contains the Cascades UI framework, which is built on top of a subset of Qt 4.8 and QtMobility modules. Apps can be created using Qt, QtMobility and QML/QtQuick. Another approach is porting an existing Qt application that uses QtGui.
Digia, community driven (open source) and 3rd party extensions targeting mobile operating systems:
Android: QT 5 port by Digia (demoed at Qt Developer Days Berlin in Nov 2012), expected to be released by the end of 2013.
iOS: QtQuick 1.0 port by Digia (demoed by Qt Developer Days Berlin in Nov 2012), expected to be released by the end of 2013.
WinRT / Windows 8: (demoed by Qt Developer Days Berlin in Nov 2012) demo.
Qt for Android port Necessitas: Has been donated to the Qt project in Nov 2012.
Qt SDK for iOS devices by Mediator Software: The product website does not contain much information, but there are regular updates on Twitter Qt4iOS (links to apps in Appstore built using QT SDK for iOS are posted on Twitter).

Downloading Qt 4.8.3

I haven't used Qt for months. But now when i want to download the latest version, I can't find the download for the last version in Qt project website there is only Qt SDK with version 4.8.1 but in the commercial version website there is 4.8.3.
so where can I download Qt SDK with Qt 4.8.3 for linux (ubuntu) ? please
I have installed the SQK with apt-get i just, and i downloaded Qt 4.8.3. what i need now is the instruction to compile it with MySQL plugins.
there is a file in the download that points to the old qt.nokia.com website so i can't find these instructions.
http://qt-project.org/downloads
try this link it might work
The details about 4.8.3 are also given in the link. I'm using Qt creator it is working fine for me.
Note for Qt 4.6.3 and Qt 4.7.3 development
Qt SDK 1.2 contains only the latest targets for developing applications for Symbian platforms. If you wish to work with Qt 4.6.3 for Symbian or Qt 4.7.3 for Symbian^3 and Symbian Anna please use Qt SDK 1.1.2. Once you have installed Qt SDK 1.1.2, to enable use of the earlier targets and App TRK, don’t run the SDK update as this will remove the features you need.
Please be aware that if you want to use the Qt SDK 1.1.2 and Qt SDK 1.2.1 on the same computer, you should install them into separate user accounts.
Qt SDK 1.1.2 can be found here.
This is what mentioned in the site. I think there is no such version for Qt SDK

Qt for Symbian S60 - "Feature not supported"

I'm developing an application with Qt for the Symbian platform, and I ran into a problem when testing the app on an S60 phone, Nokia E90.
The application compiles just fine, but when I'm installing the sis-file the phone notifies me that a "Feature is not supported".
Here's a list of capabilities that I'm using:
LocalServices ReadUserData WriteUserData NetworkServices
UserEnvironment Location ReadDeviceData NetworkControl
I'm also using Qt Mobility:
systeminfo bearer location
The app installs just fine on Symbian^3, but not on S60. What could be the problem?
Best regards
the question is which version of QtSDK do you use. QtSDK 1.1 does not support S60 anymore. Only Symbian^1 (5th generation) and Symbian^3 are supported by QtSDK 1.1 .
S60 devices are supported only by the QtSDK 1.0.
Best Regards

how to develop for a nokia phone?

i'm a little bit confused about all the different nokia SDK, what do i need to develop apps with c++?
the nokia QT sdk oder the nokia symbian^3 SDK
You can use either one. Obviously, if you want to develop Qt-based Symbian apps you will need the Nokia Qt SDK. However, Nokia has clearly and repeatedly stated that Qt is the future of Symbian development going forward, so for all new code, use the Nokia Qt SDK.
