QT连接MYSQL问题 [复制链接]

bool createConnection()
{
    QSqlDatabase db = QSqlDatabase::addDatabase("QMYSQL3");
    db.setHostName("192.168.136.141");//
    db.setDatabaseName("agvc");
    db.setUserName("root");
    db.setPassword("root");
    if (!db.open())
    {
        QMessageBox::warning(0, QObject::tr("Database Error"),
                             db.lastError().text());
        return false;
    }
    return true;
}

程序在Windows下运行正常，在Unix下报错：Client does not support authentication protocol requested by server;consider upgrading MySql Client   MYSQL: Unable to connect
这是QT连接mysql的库有关系吗？

libqsqlmysql.so是要调用libmysqlclient这个共享库的。
