我的解答思路和尝试过的方法

windows安装版试了很多遍安装不上，windows免安装版有些命令没有，所以尝试编译安装

我想要达到的结果

编译 mysql-5.6.51成功，解决3个错误

univ.i 文件片段

functional:979:19 文件片段

参考一下这篇文章，有提到你的问题，还有编译遇到的其它问题

题主，请问你是在windows上调用mysql编译呢，还是在linux上呢？
如果是在Windows上安装mysql（官网安装包mysql-installer-community-5.6.51.0.msi）失败，请参考之前写的一篇博客
一招干净卸载mysql_chexlong的博客-CSDN博客

如果是linux上安装，假如是ubuntu，mysql安装包（MySQL-5.6.51-1.el7.x86_64.rpm-bundle.tar）
官网地址：https://downloads.mysql.com/archives/community/
安装后一般配置了头文件路径，链接了动态库后可直接编译。
