如何解决类似 “警告：中发现的调试信息 ”错误/usr/lib/debug/usr/lib/php5/20100525/mysql.so“ 不匹配”/ usr/lib中/ PHP5 /20100525/mysql.so“（CRC不匹配）。”？有趣的是，其他php扩展的符号是可以的，但只适用于mysql，mysqli，postgres失败。

Debian Wheezy 7.6，所有的php软件包都是5.4.41-0+deb7u1。

如何解决类似错误warning: the debug information found in "/usr/lib/debug/usr/lib/php5/20100525/mysql.so" does not match "/usr/lib/php5/20100525/mysql.so" (CRC mismatch).

警告告诉你，从两个.so库附带的软件包在不同的版本，你应该更新-dbg包在与安装mysql包。

此命令：

dpkg -S /usr/lib/debug/usr/lib/php5/20100525/mysql.so \ 
    /usr/lib/php5/20100525/mysql.so 

会告诉你哪些包的.so期从进来。此命令：

dpkg -l <package1> <package2> 

会告诉你他们的安装版本。
