Download Qt, the cross-platform application framework

  • Qt libraries version 4.8
  • Simulator for Symbian phones and the Nokia N9
  • Qt Creator IDE version 2.4.1
  • Qt Mobility version 1.2
  • Qt development tools
  • Remote compilers

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 on the same computer, you should install them into separate user accounts.

Qt SDK 1.1.2 can be found in here.

Important information for apps targeting Symbian Belle
Please note that apps built with the Qt 4.7.4 Symbian Belle target must be identified as being for Belle phones only when submitted to Nokia Store. For more details see here. For applications you wish to distribute to all Qt 4.7.4 enabled phones, we recommend you build against the Qt 4.7.4 Symbian Anna target.
