A new universal SDK is in the works by Nokia that will unify the Qt SDK's of all platforms into one and so simplify the process of porting apps into different platforms. A first Technology preview of this new SDK was released yesterday

This mew SDK based on Qt 4.7 merges the Nokia Qt SDK 1.0 and all previous SDK and makes it easier for Symbian developers to use native APIs in their code as well as experience the latest in tools support for Qt based developement.

The SDK includes:

  • Qt Creator 2.1 RC, with tooling support for Qt Quick
  • Qt 4.7.1 for Symbian^1 and Symbian^3
  • Qt Mobility 1.1 for Symbian^1 and Symbian^3
  • Qt 4.7 for Maemo (N900)
  • Qt 4.7 Simulator
  • Support for Qt Quick and Qt Creator 2.1

The SDK is available for the following Operating Systems:

  • Microsoft Windows (XP with Service Pack 2, Vista, 7) both 32bit and 64bit
  • Ubuntu Linux 8.04 or later (different versions for 32bit and 64bit)
  • Apple Mac OS X 10.6 or later (only 64bit)

The significance of this new SDK is great considering the long feedback from developers that was utilised by Nokia into bringing all the new features and especially greater support for native APIs.Remote compiler has also been greatly updated and Notifications API is now part of the SDK. We should note that this SDK is not meant to be a final product so any Apps coded on it won't be accepted by the Ovi store due to stability reasons that may occur.

Along with this new SDK, Nokia anounced 2 competitions for developers:

  • Qtest Mobile App Port: With a €10,000 and five Nokia N900 as prizes for porting a Qt desktop application to Mobile, developers will surely start exploring the new SDK and in general mobile Qt to port their applications something really needed for Symbian and Maemo/MeeGo currently. The competition will run till the end of February. For More Info about the competition click here
  • The Quick Competition 2011Q1:This competition by Forum Nokia is willing to move current WRT developers into Qt QML as well as already active web developers from other platforms into entering the Symbian/MeeGo mobile market. But this competition is not stricly around developing an app. Participants can either create a new project on Forum Nokia which will make use of a Qt Quick element or add a new article to the Wiki in order to help future developers. The winners will get a Nokia E7-00. More info can be found here.
