      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
