在Mac OS 10.6 Snow Leopard上安装MySQL_python 1.2.2时的GCC错误
我正在尝试在Snow Leopard上安装MySQL_python 1.2.2(我特别需要这个版本,而不是最新的1.2.3),但是遇到了下面的错误。
安装命令:
pip install -Iv http://sourceforge.net/projects/mysql-python/files/mysql-python/1.2.2/MySQL-python-1.2.2.tar.gz/download
还有一部分错误信息:

有没有人见过这个错误?

根据错误提示,某些东西被重新定义了。过去我解决这个问题的方法是把出问题的声明在库的源代码中注释掉。不过,这个办法显然有一些明显的问题……

我快速在谷歌上搜索了一下,找到了这个答案:
为了让mysqldb在Leopard系统上正常工作,我发现需要编辑一下_mysql.c文件,把里面的某些行删掉:
#ifndef uint #define uint unsigned int #endif
我还需要编辑site.cfg文件,把threadsafe的选项改成False。
做完这些后,我终于成功安装了MySQLdb,太好了!不过,事情并没有那么简单,接下来又出现了一个问题:
错误提示:来自.../_mysql.so,原因是找不到这个文件。
解决办法是:
sudo ln -s /usr/local/mysql/lib/ /usr/local/mysql/lib/mysql
