can not connect to mysql using Qt help me please

[abdol]

Hi every one,
I am trying to build the mysql connection/drivers and connect to it using Qt (latest libraries 2.2) and mysql 5.5.13 community edition.

I have built the qt libraries and qt creator on my computer (using the method recommended in the Qt documentation, qmake, make, ...)

I also compiled mysql on my computer using mysql online documentation.

I managed to create libqsqlmysql.dylib and libqsqlmysql_debug.dylib and installed them in

/usr/local/Trolltech/Qt-4.7.3/plugins/sqldrivers

where my qt is installed. when i run the following code

#include <QtCore/QCoreApplication>
#include <QtSql>
#include <QtDebug>
 
int main(int argc, char *argv[])
{
    QCoreApplication a(argc, argv);
    QSqlDatabase * db = new QSqlDatabase;
 
    qDebug() << db->drivers();
    qDebug() << QCoreApplication::libraryPaths();
    return 1;
}

#include <QtCore/QCoreApplication>
#include <QtSql>
#include <QtDebug>

int main(int argc, char *argv[])
{
    QCoreApplication a(argc, argv);
    QSqlDatabase * db = new QSqlDatabase;

    qDebug() << db->drivers();
    qDebug() << QCoreApplication::libraryPaths();
    return 1;
}

To copy to clipboard, switch view to plain text mode 

i only get
("QSQLITE", "QODBC3", "QODBC")

why mysql's driver is not loading?

I am new to Qt and my platform is mac os x 10.6.7. I appreciate your help and in need of it.
