        @qxoz: Nope, nothing has changed.
        @SGaist: Nope, I don't. Nothing has changed when I did so.

          Try to update the PATH of you run environment so that it also points to the folder where the mysql dlls are

              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
