windows平台python 2.7环境编译安装zbarlight

类似于前一篇博文，http://www.cnblogs.com/zhongtang/p/7148082.html中描述的情况。

编译zbarlight同样出现问题，简要处理步骤如下：

1、到https://pypi.python.org/pypi/zbarlight下载源文件。

File	Type	Py Version	Uploaded on	Size
zbarlight-1.2.tar.gz (md5)	Source		2017-03-09	5KB

2、解压到桌面目录，C:\Users\zou\Desktop\zbarlight\zbarlight-1.2>

修改setup.py文件，增加红色字体三行内容，如下：

    ext_modules=[
        Extension(
            name=str('zbarlight._zbarlight'),
            sources=[str('src/zbarlight/_zbarlight.c')],
            extra_compile_args=['-std=c99'],
            libraries=['libzbar-0'],
            library_dirs= ['C:\Program Files (x86)\ZBar\lib' ] ,
            include_dirs = [ 'C:\Program Files (x86)\ZBar\include' ],
            optional=os.environ.get('READTHEDOCS', False),  # Do not build on Read the Docs
        ),
    ],

3、手工编译安装，成功：
