[ReasyEasyPeasy]

Hey guys,
first of all english isnt my first language. And please talk to me like you would talk to a little stupid kid .
I can connect to the database with Qt 5.4 but 5.5 dont work. I get the following error text:
Error:

QSqlDatabase: QMYSQL driver not loaded
QSqlDatabase: available drivers: QSQLITE QMYSQL QMYSQL3 QPSQL QPSQL7
Something went Wrong: "Driver not loaded Driver not loaded"
("/home/samuel/Qt/5.5/gcc_64/plugins", "/home/samuel/Documents/build-Arbeit-Desktop_Qt_5_5_0_GCC_64bit-Debug")

With the following code;

#include <QApplication>
#include <QtCore/QCoreApplication>
#include <QtSql>
#include <QtDebug>
int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
    QSqlDatabase db = QSqlDatabase::addDatabase("QMYSQL");
    db.setConnectOptions();
    db.setHostName("localhost");
    db.setDatabaseName("test");
    db.setUserName("root");
    db.setPassword("1234");
    if(db.open()) {
        qDebug() << "Opened!";
        db.close();
    }
    else {
        qDebug() << "Something went Wrong:" << db.lastError().text();
        qDebug() << QCoreApplication::libraryPaths();
    }
 
    return a.exec();
}

#include <QApplication>
#include <QtCore/QCoreApplication>
#include <QtSql>
#include <QtDebug>
int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
    QSqlDatabase db = QSqlDatabase::addDatabase("QMYSQL");
    db.setConnectOptions();
    db.setHostName("localhost");
    db.setDatabaseName("test");
    db.setUserName("root");
    db.setPassword("1234");
    if(db.open()) {
        qDebug() << "Opened!";
        db.close();
    }
    else {
        qDebug() << "Something went Wrong:" << db.lastError().text();
        qDebug() << QCoreApplication::libraryPaths();
    }

    return a.exec();
}
