Supported Platforms and Compilers
Qt has been written with extreme cross-platform portability in mind. Qt-based applications therefore run on a wide variety of operating systems/platforms: Windows 2000 through Vista, Mac OS X 10.3 (Panther) through 10.5 (Leopard) and a wide variety of X11 based systems (Linux, embedded Linux, AIX, HP-UX, IRIX, Solaris and more).
Qt itself will compile on a wide variety of both platform-specific and cross-platform C++ compilers.
The exact list of supported platforms and compilers that Qt will run on will vary by release. Below you will find information about various Qt versions, starting with Qt 4.3.
Qt 4.3
- Supported platforms: http://doc.trolltech.com/4.3/platform-notes-platforms.html
- Supported compilers: http://doc.trolltech.com/4.3/compiler-notes.html
Qt 4.4
- Supported platforms: http://doc.trolltech.com/4.4/supported-platforms.html
- Support for Windows CE will be added.
- Supported compilers: http://doc.trolltech.com/4.4/compiler-notes.html
- Visual Studio 2002 will no longer be supported.
- Visual Studio 6
will not be supported in new functionality such as WebKit, XPath/XQuery and QtConcurrent.
- Visual Studio 2008 now is officially supported.
- Note: If you are using Visual Studio 2005, please note that you will need to install Service Pack 1 in order for Qt 4.4 to work properly.
- Visual Studio 2002 will no longer be supported.
New 4.4 features support
Certain of the new features in Qt rely on modern compiler functionality and will therefore not work with some legacy compiler. In the matrix below, "X" means that a module should work with a given compiler, "-" that it will not.
