问题与Qt的4.7.2

Question

建设的MySQL插件我这里有以建设MySQL驱动程序使用Qt 4.7.2

我已经安装的Qt 4.7.2 VS2008和MySQL 5.5.9社区版的连接体问题，无论是在没有空格的路径（C：\ Qt中，C：\ MySQL的）。 我把从Qt的文档的命令和创建Makefile文件都没有问题，只有消息：

C:\Qt\4.7.2\src\plugins\sqldrivers\mysql>C:\Qt\4.7.2\bin\qmake "INCLUDEPATH+=C:\MySQL\include" "LIBS+=C:\MYSQL\lib\libmysql.lib" mysql.pro 
WARNING: (internal):1: Unescaped backslashes are deprecated. 
WARNING: (internal):1: Unescaped backslashes are deprecated. 
WARNING: (internal):1: Unescaped backslashes are deprecated. 

然后我运行NMAKE，并得到以下结果：

C:\Qt\4.7.2\src\plugins\sqldrivers\mysql>nmake

在了Qt -Doc是MySQL库的另一个路径，但是我改变了它。我没有选择路径，在libaries该文件夹中的上方。

我试图在VS2008/2010命令提示符下构建插件，没有任何区别。

希望有人能帮助我，谢谢

Answer 1

MasterMito找到解决方案himself：

解决了这一问题：安装了MySQL，服务器的32位版本。

Answer 2

安装32位版本解决了我的问题。 但是，这样做确保已安装的版本完全去除和MySQL服务没有运行。你可以从任务管理器 - >服务中查看。如果服务已经运行，您可以停止服务。

执行实例配置时，安装mysql-5.5.33-win32.msi时总会导致挂起。所以，我安装了zip并手动启动了mysql服务。
