Installing Qt/Windows

1. 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. 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.

2. Uncompress the files into the directory you want Qt installed; e.g. C:\Qt\4.0.1.

   NOTE: The install path must not contain any spaces.

3. Building

   To configure the Qt library for your machine type:

       C:
       cd \Qt\4.0.1
       configure

   Type configure -help to get a list of all available options.

   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:

             nmake

4. Environment variables

   In order to use Qt, some environment variables needs to be extended.

             PATH               - to locate qmake, moc and other Qt tools

   This is done by adding c:\Qt\4.0.1\bin to the PATH variable.

   For newer versions of Windows, PATH can be extended through "Control Panel->System->Advanced->Environment variables" and for older versions by editing c:\autoexec.bat.

5. That's all. Qt is now installed.

   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.
