Installing Qt for Windows
Qt for Windows has some requirements that are given in more detail in the Qt for Windows Requirements document.
If you have obtained a binary package for this platform, consult the installation instructions provided instead of the ones in this document.
Open Source Versions of Qt is not officially supported for use with any version of Visual Studio. Integration with Visual Studio is available as part of the Qt Commercial Edition.
Step 1: Install the License File (commercial editions only)
If you have the commercial edition of Qt, copy the license file from your account on dist.trolltech.com into your home directory (this may be known as the
userprofile environment variable) and rename it to
.qt-license. This renaming process must be done using a command prompt on Windows, not with Windows Explorer. For example on Windows 2000,
%USERPROFILE% should be something like
C:\Documents and Settings\username
For the open source version you do not need a license file.
Step 2: Unpack the Archive
Uncompress the files into the directory you want Qt installed; e.g.
Note: The install path must not contain any spaces or Windows specific file system characters.
Step 3: Set the Environment variables
In order to build and use Qt, the
PATH environment variable needs to be extended:
PATH - to locate qmake, moc and other Qt tools
This is done by adding
c:\Qt\%VERSION%\bin to the
For newer versions of Windows,
PATH can be extended through the Control Panel|System|Advanced|Environment variables menu.
You may also need to ensure that the locations of your compiler and other build tools are listed in the
PATH variable. This will depend on your choice of software development environment.
Note: If you don't use the configured shells, which is available in the application menu, in the Open Source Versions of Qt,
configure requires that
sh.exe is not in the path or that it is run from
msys. This also goes for mingw32-make.
Step 4: Build the Qt Library
To configure the Qt library for your machine, type the following command in a Visual Studio command prompt:
C: cd /D C:\Qt\%VERSION% configure
configure -help to get a list of all available options. The Configuration Options for Qt page gives a brief overview of these.
If you have multiple compilers installed, and want to build the Qt library using a specific compiler, you must specify a
qmake specification. This is done by pasing
-platform <spec> to configure; for example:
configure -platform win32-msvc
In some cases you need to set up the compilation environment before running configure in order to use the right compiler. For instance, you need to do this if you have Visual Studio 2005 installed and want to compile Qt using the x64 compiler because the 32-bit and 64-bit compiler both use the same
qmake specification file. This is usually done by selecting Microsoft Visual Studio 2005|Visual Studio Tools|<Command Prompt> from the Start menu.
The actual commands needed to build Qt depends on your development system. For Microsoft Visual Studio to create the library and compile all the demos, examples, tools and tutorials type:
Note: If you later need to reconfigure and rebuild Qt from the same location, ensure that all traces of the previous configuration are removed by entering the build directory and typing
nmake distclean before running
That's all. Qt is now installed.
Qt Demos and Examples
If you are new to Qt, we suggest that you take a look at the demos and examples to see Qt in action. Run the Qt Examples and Demos either by typing
qtdemo on the command line or through the desktop's Start menu.
