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.
You can develop with Qt on the following desktop platforms:
You can develop with Qt for the following embedded platforms:
- Embedded Android
- Embedded Linux (DirectFB, EGLFS, KMS, and Wayland)
- Windows Embedded (Compact and Standard)
- Real-Time Operating Systems, such as QNX, VxWorks and INTEGRITY
You can develop with Qt for the following mobile platforms supported by Digia:
The following platforms also support Qt:
Work in progress ports of Qt exist for:
- WinRT (including Windows Phone)
For more information about the Qt modules for mobile platforms, visit the Mobile APIs page.
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:
|Ubuntu Linux 11.10, X11 (32-bit and 64-bit)||As provided by Ubuntu|
|Ubuntu Linux 12.04, X11 (64-bit)||As provided by Ubuntu|
|Microsoft Windows 7 (32-bit)||MSVC 2010 SP1|
|Microsoft Windows 7 (32-bit)||MinGW-builds gcc 4.8.0 (32-bit)|
|Microsoft Windows 8 (32-bit and 64-bit)||MSVC 2012 SP2|
|Microsoft Windows 8.1 (32-bit and 64-bit)||MSVC 2012 SP2|
|Apple Mac OS X 10.7 "Lion", Cocoa (64-bit)||Clang as provided by Apple|
|Apple Mac OS X 10.8 "Mountain Lion", Cocoa (64-bit)||Clang as provided by Apple|
|Apple Mac OS X 10.9 "Mavericks", Cocoa (64-bit)||Clang as provided by Apple|
|Apple iOS 6||Clang as provided by Apple|
|Google Android 4.2||As provided by Google (Android NDK 4.8)|
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:
|Ubuntu Linux 10.04, X11 (32-bit)||As provided by Ubuntu|
|Microsoft Windows XP (32-bit)||MSVC 2008|
|Apple Mac OS X 10.6 "Snow Leopard", Cocoa (32-bit)||GCC as provided by Apple|
Digia, Qt partners, open source projects and community users are able to provide assistance with various different supported platforms and configurations.
Availability of Packages
The Qt Project provides binary Qt installation packages for all of the reference platforms from http://qt-project.org/downloads. The site provides download links for all supported development platforms. The Qt Installation Program page has more information about the installers.
Source packages are also found in the downloads page. The Building Qt Sources page has more information about compiling Qt from the source packages.
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.
