mac xcode5.1安装Mysql-python编译错误解决

前几天才入的macbook air，在 app store 安装的xcode和command_line_tools都是最新版本，结果我被坑了，编译工具太新了，不兼容，出现错误。

<code><span class="pln">clang</span><span class="pun">:</span><span class="pln"> error</span><span class="pun">:</span><span class="pln"> unknown argument</span><span class="pun">:</span><span class="pln"> </span><span class="str">'-mno-fused-madd'</span><span class="pln"> </span><span class="pun">[-</span><span class="typ">Wunused</span><span class="pun">-</span><span class="pln">command</span><span class="pun">-</span><span class="pln">line</span><span class="pun">-</span><span class="pln">argument</span><span class="pun">-</span><span class="pln">hard</span><span class="pun">-</span><span class="pln">error</span><span class="pun">-</span><span class="kwd">in</span><span class="pun">-</span><span class="pln">future</span><span class="pun">]</span></code>

我在mysql-python.sourceforge.net下载MySQL-python-1.2.4b4.tar.gz 

shell cmd :

   tar -cjf MySQL-python-1.2.4b4.tar.gz 

   cd MySQL-python-1.2.4b4 

   python setup.py build

然后出现下面都错误代码

说一下问题分析过程，我开始分析  setup.py里面的代码，想找出编译选项-mno-fused-madd，然后将它删除，可是找了半天没找到，

发现python调用的是setuptools模块，我就去找这个模块的代码，最后发现是一个egg包，没办法去看它的源码。

最后没办法了，我想了一下应该是我的编译工具太新了的原因。

最后成功解决办法：

我在网上找到xcode5.0.2和老一点版本的command_line_tools的dmg包

卸载xcode5.1然后安装这两个包，最后问题解决了！！！
