如果你有陈旧的vs2003编译器，那么这篇短文或者意义不是很大，
http://blog.donews.com/tekjian/archive/2006/08/06/990279.aspx 有简单的介绍如何直接安装这个玩意儿。
但是，现在很多人都用上了vs2005或者vs2008，可是python还是用的2.5.x版。这个时候痛苦就来了，
下载完python-sybase-0.38之后，如果你执行：
python setup.py intall,
肯定会出这样的错：
error: Python was built with Visual Studio 2003;extensions must be built with a compiler than can generate compatible binaries.Visual Studio 2003 was not found on this system. If you have Cygwin installed,you can try compiling with MingW32, by passing "-c mingw32" to setup.py.
经过若干周折，发现，有办法绕过去，让vs2008直接支持编译安装。
先让sybase.bat环境变量生效，接着让vcvars.bat生效，(即执行这两个 bat)
把ASE15.x\OCS-150\lib下的三个文件libsyb*.lib,重命名为lib*.lib, 这三个新文件是：libct.lib, libcs.lib, libblk.lib
然后要修改python\Lib\distutils\msvccomiler.py, 找到：
# x86 if self.__version >= 7: self.__root = r"Software\Microsoft\VisualStudio" self.__macros = MacroExpander(self.__version) else: self.__root = r"Software\Microsoft\Devstudio"注释掉这一行：self.__macros = MacroExpander(self.__version)
之后，把对应的pyc文件删掉，让它强制重新编译。
设置两个环境变量：set DISTUTILS_USE_SDK=1
set MSSdk=1
这之后执行python setup.py install, 就可以完全成功的安装了。
以下是详细的编译安装结果：

经此实验，可以确定不一定要安装vc7,就可以安装一些要编译的python模块了。 当然，如果你机器上可以安装，最省事儿了。至于vc7，你完全可以自己整理出一个解压缩的绿色包，也就20来兆的样子。
