Question

我只是使用mysql站点的示例代码。如果我在调试中执行它，该程序将编译并运行。如果我在发布中编译它会给我标题中的错误。我从oracle网站下载了所有的连接器和服务器，所以一切都是最新的。我甚至编译了最新版本的c ++连接器和c连接器。我已经对此进行了大量搜索并尝试了他们所说的，但无法解决这个问题。我看到的lib和dll文件中列出了mysql_get_option函数。我确保我的计算机上没有丢失的dll或lib文件。我检查了系统路径变量，以确保它没有指向某个随机区域。我正在使用Vs2013。

请帮助我试着解决这个问题一个星期，我的大脑即将爆炸！谢谢你的任何建议。

P.S。我作为一个爱好编程，所以我很可能忽略了一些微不足道的事情。

我用Google搜索了您的帖子标题，找到了这个链接：http://www.linuxtalks.net/mysql-community-server-5-7-4-m14-has-been-released/

如果您搜索 mysql_get_option 的页面，您会看到他们修复了这个已知错误。如果您正在使用VS2013，那么您的库版本可能包含此错误，因为该页面指的是2014年的版本。

无法在dll libmysql.dll中找到过程入口点mysql_get_option
