3.我的电脑上右键->属性->高级->环境变量
在环境变量path中添加;D:\qt\bin (;是用来和其它环境变量分开的)
新建环境变量:QMAKESPEC值win32-msvc.net

4.解压qt-win-commercial-src-4.3.1.zip到d:\qt

5.检查d盘空间
ntfs下占用空间为949 MB (995,687,822 字节) , 带文件压缩的情况下
fat32下大小为1.96 GB (2,108,853,199 字节) , 实际占用空间会更多
另外考虑到盘上需要留一定的空间出来,

6.把d:\qt下的.LICENSE文件复制到系统盘的用户目录下
如C:\Documents and Settings\Administrator

7.开始->所有程序->Microsoft Visual Studio 2005->Visual Studio Tools->Visual Studio 2005 命令提示
输入下面命令
d:
cd qt
configure (可以只选择一部分的configure -help可以看到选项)
y
(y了以后得等好一段时间了,可能有几十分钟.....可以去玩)
nmake
(哇哈哈,先去吃饭...会等很久的,可能是1个半小时,当然可以不选择完全编译的)

8.运行qt-vsintegration-1.3.1.exe一路next直到安装成功

9.运行vs2005->工具(tools)->选项(options)->qt->builds->add->4.3.1 d:\qt

10.新建项目,选择qt的.....ctrl+f5就可以了

安装说明原文:
                          INSTALLING Qt/Windows Version 4.3.1

Note: If you have obtained a binary package for this platform, consult the
installation instructions provided instead of the ones in this document.

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\4.3.1.

    NOTE: The install path must not contain any spaces.

3. 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\4.3.1\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.

4.  Building

    To configure the Qt library for your machine type:

        C:
        cd \Qt\4.3.1
        configure

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

    If you are using the "-direct3d" option, make sure that you have
    the Direct3D SDK installed, and that you have run the
    %DXSDK_DIR%\Utilities\Bin\dx_setenv.cmd command, before attempting
    to run configure.

    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

    If you 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 confclean

    before running the configure script again.

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.

    We hope you will enjoy using Qt. Good luck!
