Has anyone had any success connecting to MySQL embedded?

[galrub]

Hello all,

I'm trying to connect to MySql embedded using QT, but get and error:
@
mysql_embedded: Unknown error 1146
110923 20:54:22 InnoDB: The InnoDB memory heap is disabled
110923 20:54:22 InnoDB: Mutexes and rw_locks use Windows interlocked functions

as far as I can understand I need to tell the QSqlDatabase object to use the my-xxx.ini, or somehow pass to it the configurations.
any ideas?
