總結

1.zbar官方的版本只支持到python2.6，非官方的版本有支持2.7的msi文件，但是我的不知道爲什麼，還是不能import zbar，故我採用的是第二種方法
2.流程

1. 安裝mingw 5.1.6
2. 安裝zbar reader （即zbar的exe包）
3. 下載zbar源文件
4. 修改setup.py文件

ext_modules = [
        Extension('zbar', [
                'zbarmodule.c',
                'enum.c',
                'exception.c',
                'symbol.c',
                'symbolset.c',
                'symboliter.c',
                'image.c',
                'processor.c',
                'imagescanner.c',
                'decoder.c',
                'scanner.c',
                ],
            library_dirs = ['C:\Program Files (x86)\ZBar\lib' ] ,
            libraries= ['libzbar-0'],
            include_dirs = ['C:\Program Files (x86)\ZBar\include'],
        ),

5. 執行安裝

d:\src\>python setup.py install
running install
running build
running build_ext

running install_egg_info
Writing c:\python27\Lib\site-packages\zbar-0.10-py2.7.egg-info

最後會在 …\python27\Lib\site-packages 路徑下生成 zbar.pyd ，此時，zbar已經安裝成功，使用import zbar成功
