我想使用cl-dbi连接mysql.

在使用quicklisp在sbcl上安装cl-dbi之后,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)))

(CFFI::FL-ERROR "Unable to load foreign library (~A).~%  ~A" LIBMYSQLCLIENT "Error opening shared object \"libmysqlclient_r.so\":

环境信息：
操作系统：Debian 8.1
的mysql：5.5.43-0 deb8u1
sbcl：SBCL 1.2.4.debian

也无法使用cl-mysql clsql.

有人可以提供一些线索吗？

解决方法:

谷歌之后,从post和问题的建议是固定的.

> $sudo find / -name *libmysqlclient* /usr/share/doc/libmysqlclient18
> /usr/lib/i386-linux-gnu/libmysqlclient.so.18
> /usr/lib/i386-linux-gnu/libmysqlclient.so.18.0.0
> /usr/lib/i386-linux-gnu/libmysqlclient_r.so.18
> /usr/lib/i386-linux-gnu/libmysqlclient_r.so.18.0.0
> /var/cache/apt/archives/libmysqlclient18_5.5.42-1_i386.deb
> /var/cache/apt/archives/libmysqlclient18_5.5.43-0+deb8u1_i386.deb
> /var/lib/dpkg/info/libmysqlclient18:i386.postinst

> /var/lib/dpkg/info/libmysqlclient18:i386.shlibs
> /var/lib/dpkg/info/libmysqlclient18:i386.md5sums

只需创建libmysqlclient_r.so作为指向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,它会成功运行.
