        I faced this issue before. try to fix it as following:

        • put libmysql.dll in your application path (not in your project path in case you configured run from shadow build path)
        • put SQLDrivers folder in your application's path

                    Sorry my mistake, I forgot you use 12.04 (I'm using 13.04) just call:
                    [code]sudo apt-get install libqt4-sql-mysql[/code]

                        IIRC, you need to also install libmysqlclient-dev
