MySQL UDF Lib安装

我正在尝试安装和使用MySql UDF Lib,但我在安装过程中遇到了ELF错误。

我在Ubuntu 14.04LTS 64下。

尝试关注其他人的答案并为编译器添加-m64标志,但仍然有错误。

免责声明:我不是Linux专家,只是尝试解决程序问题

答案 0 :(得分:0)

有点迟到的反应,但比我希望的更好:)

您正在将插件安装到/usr/lib

gcc -fPIC -Wall -m64 -I/usr/include/mysql -I. -shared lib_mysqludf_sys.c -o /usr/lib/lib_mysqludf_sys.so

但是你的MySQL服务器只是在寻找/usr/lib/mysql/plugin上安装的插件。

所以,将上面的gcc命令改为

gcc -fPIC -Wall -m64 -I/usr/include/mysql -I. -shared lib_mysqludf_sys.c -o /usr/lib/mysql/plugin/lib_mysqludf_sys.so

应修正Can't open shared library 'lib_mysqludf_sys.so'错误。

希望这有帮助。
