在windows 上安装 qt

从这里 http://qt.nokia.com/downloads 下载你需要 的版本

我安装的是 ：Qt SDK: Complete Development Environment

我安装是这个版本

安装完后，启动qt command prompt

"

Setting up a MinGW/Qt only environment..

-- QTDIR set to E:/Qt/2010.05/qt

-- PATH set to E:/Qt/2010.05/qt/bin

-- Adding E:/Qt/2010.05/bin to PATH

-- Adding C:/WINDOWS/System32 to PATH

-- QMAKESPEC set to win32-g++

"

但我想用vc编译， qmake -tp vc 结果

WARNING: Unable to generate output for: //Makefile.Debug [TEMPLATE vc]

原因出在这句 "QMAKESPEC set to win32-g++"

改为QMAKESPEC set to msvc-2008.

编译有错:

LINK : fatal error LNK1181: cannot open input file qtmaind.lib

解决方案：

•

Add this 2 paths to the Environment Variables: “C:/Qt/2009.01/bin” and “C:/Qt/2009.01/qt/bin”. Note: This path will depend where you install the Qt.

•

To add to the path: Control Panel > System > Advanced > Environment Variables

•

Select “PATH” under system variables. Click “EDIT” and Add this to the end of the line: C:/Qt/2009.01/bin; C:/Qt/2009.01/qt/bin (Remember to separate two paths with a “;”)

STEP 3: CONFIGURE QT FOR YOUR MACHINE

•

Run the Visual Studio Command prompt. Start > Program Files > Visual Studio > Visual Studio Tools > Visual Studio Command Prompt

•

Go to the path of your installed Qt e.g. cd C:/Qt/2009.01/qt

•

At the prompt type the command configure. E.g. C:/Qt/2009.01/qt> configure

•

This will configure Qt for your machine. In case 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. E.g. configure -platform win32-msvc

STEP 4: BUILDING QT FOR VISUAL STUDIO

•

Run nmake at the command prompt

•

This takes lots of time. Will build all the demos, examples and libraries.

That’s it QT is now installed. You can follow the tutorials to use Qt.

OK, it works.
