Qt is a cross-platform application and UI framework. Using Qt, you can write GUI applications once and deploy them across desktop, mobile and embedded operating systems without rewriting the source code.In Qt 5 all platforms are created using the new Qt Platform Abstraction (QPA), which makes it easier than before to port Qt into a new operating system.

Qt is supported on a variety of 32-bit and 64-bit platforms, and can usually be built on each platform with GCC, a vendor-supplied compiler, or a third party compiler. Open GL (ES) 2.0 or DirectX 9 (with ANGLE) is required for Qt Quick 2. Widgets and Qt Quick 1 can be used also without hardware acceleration.

Desktop Platforms

You can develop with Qt on the following desktop platforms:

• Windows
• Linux/X11
• OS X

Embedded Platforms

You can develop with Qt for the following embedded platforms:

• Embedded Android
• Embedded Linux
• Windows Embedded (Compact and Standard)
• Real-Time Operating Systems, such as QNX, VxWorks and INTEGRITY

Mobile Platforms

You can develop with Qt for the following mobile platforms supported by Digia:

• Android
• iOS
• WinRT (including Windows Phone)

The following platforms also support Qt:

• BlackBerry 10
• Sailfish OS

Work in progress ports of Qt exist for:

• Tizen

Reference Configurations

A reference configuration is a combination of an operating system version, a compiler version, and a graphics system. The following table lists the configurations that are tested by the Qt Project:

These reference configurations are run on the continuous integration (CI) system within Qt Project. In addition, they are subjected to unit test suite and other internal testing tools on a frequent basis (prior to new version releases, source tree branching, and at other significant period points in the development process). Errors or bugs discovered in these platforms are prioritized for correction. Significant errors discovered in tested configurations can impact release dates.

Any configurations not listed above are not actively tested by the Qt Project. However, Qt may run on configurations other than those actively tested on, and additional configurations may be raised to tested state, if sufficient effort is made to bring continuous integration to an acceptable state for that particular configuration.

In addition to the reference platforms Qt is occasionally tested on other configurations in which it is known to run well. These include, for example:

Digia, Qt partners, open source projects and community users are able to provide assistance with various different supported platforms and configurations.

Availability of Packages

You can download the Qt 5 installers and source packages from the Downloads page. For more information, visit the Getting Started with Qt page.

Deployment of Qt Applications

The deployment procedure for each platform is different and they are covered in greater detail in their platform pages. Meanwhile, there is a deployment article for summarizing the deployment procedure in general.
