Qt MySQL -------- 无法打开包含文件:'mysql.h': [英] Qt MySQL -------- Cannot open include file: 'mysql.h':

问题描述

我正在用 Qt 制作一个 GUI 应用程序，它基本上是数据库的前端

Im making a GUI application in Qt, it will be a front end to a database basically

但是我什至还没有到做任何事情的地步，因为我的数据库连接一直失败(它实际上并没有编译，所以它不是数据库连接问题)

however i haven't even got to the point of doing anything yet because my database connection just keeps failing (Well it doesn't actually compile so its not a DB connection issue)

无论如何，我的项目甚至无法构建，因为 Qt 给出了错误:

Anyway my project wont even build because Qt gives the error:

 error: C1083: Cannot open include file: 'mysql.h': No such file or directory

我不是特别理解，因为在使用我包含的 QtSQL 内容的类中:

which i dont particularly understand because in the class that uses the QtSQL stuff i have included:

#include <QtSql/QSqlDatabase>
#include <QtSql/QMYSQLDriver>

现在有点把我的头撞在桌子上，因为我从文档中了解到，这两个包含的内容就是你所需要的，哦，这在我的 .pro 中

kind of banging my head against the desk now because it is my understanding from the documentation that these 2 includes are all you need, oh and this in my .pro

QT       += sql

我是否在这里遗漏了一些非常明显的东西?

am i missing something really obvious here?

干杯

推荐答案

您实际上不需要包含 QMYSQLDriver.您真正需要的是构建 mysql 驱动程序.这是 手册，告诉您如何操作.

You actually don't need to include QMYSQLDriver. What you really need is to build mysql driver. Here is the manual, which tells you how to do it.
