【问题描述】：

我正在尝试在 virtualenv 环境下的 ubuntu 12.04 中安装 mysql-python 模块，但意外遇到以下错误：

building '_mysql' extension

creating build/temp.linux-x86_64-2.7

gcc -pthread -fno-strict-aliasing -DNDEBUG -g -fwrapv -O2 -Wall

error: command 'gcc' failed with exit status 1

我已经跑了：

sudo apt-get install mysql-server mysql-client python-mysqldb libmysqlclient-dev python-dev

但它没有帮助。

【参考方案1】：

问题是 libmysqlclient.so 没有https://github.com/javer/gentoo-overlay/issues/4#issuecomment-30748799 中描述的符号链接

【参考方案2】：

对于 Centos 上的我来说，问题是 MySQL-python 没有提供 libmysqlclient_r.so，但它有其他编号的版本。通过卸载它并安装 Percona-SQL-devel，python 能够正确找到库并构建***。

【讨论】：

其实问题出在 MySQL-devel，而不是 MySQL-python。
