安装MySQL_python 1.2.2时出现GCC错误（Mac OS 10.6 Snow Leopard） [英] GCC error when installing MySQL_python 1.2.2 (Mac OS 10.6 Snow Leopard)

问题描述

我试图在Snow Leopard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），并且在下面得到这个错误。

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 
  

还有一部分跟踪：

有没有人看过这个错误？

解决方案 div>

快速谷歌搜索取得了这个答案：

为了让mysqldb在leopard上工作，我发现我必须编辑_mysql.c并编辑行：

  #ifndef uint 
 #define uin t unsigned int 
 #endif 
  

我还必须编辑site.cfg并将threadsafe标记为False。

完成此操作后，我设法安装MySQLdb，太棒了！不是很快
，还有另一个问题：
$ b $ p引用自：... / _ mysql.so原因：找不到图像$ / b>

解决方案：

pre $ sudo ln -s / usr / local / mysql / lib / / usr / local / mysql / lib / mysql


I'm trying to install MySQL_python 1.2.2 (I specifically need this version, not the current 1.2.3) on Snow Leopard, and getting this error below.

Command to install:

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

And a portion of the trace:

Has anyone seen this error before?

解决方案

A quick google search yielded this answer:

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

#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:

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