    @mbnoimi: Yea man, that's it!

    [quote author="mbnoimi" date="1366202366"]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[/quote]

    Solved.

              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
