Question

插件已编译并安装在此处qt-project.org。

libqt5sql5-mysql已安装
mysql-client已安装

代码：

QPluginLoader loader("path-to-your-driver/libqsqlmysql.so");
loader.load();
qDebug() << loader.errorString();

显示

"Unknown error"

qDebug() << QSqlDatabase::drivers();

的输出

“QSQLITE”，“QMYSQL”，“QMYSQL3”，“QPSQL”，“QPSQL7”

我有
