我一直在使用MinGW，我不得不做的就是将臭名昭着的输出复制到32位libmysql.dll文件到可执行文件所在的位置：
QSqlDatabase：未加载MYSQL驱动程序
QSqlDatabase：可用的驱动程序：QSQLITE QMYSQL QMYSQL3 QODBC QODBC3 QPSQL QPSQL7
现在我正在尝试使用MSVS2017 64位编译器编译我的应用程序。我试图使用32位和64位<style type="text/css">
html, body, #map_canvas {
margin: 0;
padding: 0;
height: 100%;
}
#map_canvas {
width : 770px;
height : 400px;
}
</style>

文件，但没有运气 - 我收到警告，QSqlDatabase无法打开。我找到了这个网站：https://wiki.qt.io/How_to_load_a_sql_driver_correctly但它似乎已经过时且含糊不清。任何已知的问题解决方案？
答案 0 :(得分：0)
使用MSVS，您需要qsqlmysql4.dll，通常需要从源代码构建MySQL驱动器，您可以按Qt documentation How to Build the QMYSQL Plugin on Windows进行操作。
