关于python：安装MySQL_python 1.2.2时出现GCC错误（Mac OS 10.6 Snow Leopard）

GCC error when installing MySQL_python 1.2.2 (Mac OS 10.6 Snow Leopard)

我正在尝试在雪豹上安装mysql_python 1.2.2(我特别需要这个版本，而不是当前的1.2.3)，并在下面得到这个错误。

要安装的命令：

1	pip install -Iv http://sourceforge.net/projects/mysql-python/files/mysql-python/1.2.2/MySQL-python-1.2.2.tar.gz/download

以及一部分痕迹：

以前有人见过这个错误吗？

谷歌快速搜索得到了这个答案：

To get mysqldb working on leopard I found I had to edit _mysql.c and edit out the lines:

1
2
3
#ifndef uint
#define uint unsigned int
#endif

I also had to edit site.cfg and mark threadsafe to False.

After doing this, I managed to get MySQLdb to install, great! Not so
fast, there was yet another problem:

Referenced from: .../_mysql.so Reason: image not found

The solution:

1
sudo ln -s /usr/local/mysql/lib/ /usr/local/mysql/lib/mysql
