Please note that as of October 24, 2014, the Nokia Developer Wiki will no longer be accepting user contributions, including new entries, edits and comments, as we begin transitioning to our new home, in the Windows Phone Development Wiki. We plan to move over the majority of the existing entries over the next few weeks. Thanks for all your past and future contributions.
How to Install Qt
Download and install the Qt SDK.
The SDK contains everything you need and the installation process is straightforward and guided. If you do need further information about the SDK, see Qt SDK for more information.
Tip: If you were referred to this article from an older article in the wiki it may have been written before the Qt SDK was created. In this case use the Qt SDK for pure Qt development on Maemo/MeeGo/Symbian. If the article uses Symbian C++ code directly, then it is still likely that you will need to use the Qt SDK, but see article Using Symbian C++ in the Qt SDK for more information on your options.
