我想用cl-dbi来连接mysql。
使用quicklisp在sbcl上安装cl-dbi后，尝试连接到mysql但失败并出现以下错误：
(let ((quicklisp-init (merge-pathnames "quicklisp/setup.lisp"
(user-homedir-pathname))))
(when (probe-file quicklisp-init)
(load quicklisp-init)))
T
* (ql:quickload :cl-dbi)

google之后，根据post提出的建议并解决了问题。

只需创建libmysqlclient_r.so作为libmysqlclient.so.18的链接
$ sudo ln /usr/lib/i386-linux-gnu/libmysqlclient.so.18 /usr/lib/i386-linux-gnu/libmysqlclient_r.so
之后，执行cl-dbi示例并成功运行。
