教程中cygwin默认安装在
C:\cygwin\ 如果您更改为其他路径请自行改变
都下载完成后开始下面的操作
首先先安装默认的cygwin 环境，否则接下来的操作会失败
----------------------------------------------------------------------------------------------------------------------------------------------------------------
1.双击setup.exe
2.按照安装提示“下一步”
3.选择从“互联网”安装：
4.选择安装的路径，一般是C:\Cygwin，选择本地临时目录，用于存放下载的软件；选择您连接互联网的方式，一般选“直接连接”就可以了。
5.选择下载源，您可以在下载列表里选择：
http://www.cygwin.cn 或者，直接在URL里输入
http://www.cygwin.cn/pub/6.根据安装提示，选择需要安装的软件包，完成安装。
----------------------------------------------------------------------------------------------------------------------------------
打开C:\tmp\setup.exe
点击安装界面上的"下一步"
来到下图页面
到上面的步骤，User URL 这里填写:
http://www.iphonegameover.com/cygwin 然后点击Add按钮，然后点击下一步
下面的操作全部直接按下一步即可，直到下载安装完毕。
完成后把 上图 的2个沟打上，方便运行cygwin
(下载可能会比较慢，请耐心等待下载完毕)
接下来打开下载的
MacOSX10.4u.sdk.rar把压缩包里面的
Archive.pax.gz解压到C:\cygwin\home\Administrator\ 目录下,没有此目录的话则手工建立该目录接下来打开下载的 iphone_image.rar把里面的
iphone image 解压到 C:\cygwin\usr\local\arm-apple-darwin\ 目录下解压完后把iphone image 文件夹改名为 filesystem完成以上操作后，基本安装已经完成，接下来在开始菜单运行那里输入"C:\cygwin\Cygwin.bat" 屏幕显示
Checking if /Developer/SDKs/MacOSX10.4u.sdk exists... no!
Do you wish to install the XCode 2.5 header files now? (y/n)
按Y 继续
然后屏幕显示
Found 'Archive.pax.gz' in current directory.
Extracting /home/Administrator/Archive.pax.gz...
这里会很长时间停顿，大概1分钟左右
然后屏幕显示
Checking if /usr/local/arm-apple-darwin/include exists... checking for a BSD-com

checking for /Developer/SDKs/MacOSX10.4u.sdk/usr/include/TargetConditionals.h...
no
configure: error: You must have a copy of the Mac OS X 10.4 Universal SDK. Pleas
e see the wiki at
http://iphone-dev.googlecode.com/ for information on how to ob
tain this. If you already have the SDK use a --with-macosx-sdk=path option to sp
ecify the path.
Error: Files don't appear to have been installed!
Would you like to delete this script? (y/n):
按 n 之后关闭cygwin
打开 C:\cygwin\Developer\Developer
把该目录下的SDKs 移动到C:\cygwin\Developer\ 目录下
删除C:\cygwin\Developer\Developer 目录
重新打开cygwin
接下来会自动完成安装，此时屏幕应该显示如下内容
Checking if /usr/local/arm-apple-darwin/filesystem exists... yes
