    macports and brew are package manager for OS X, install one of them, and from there install MySQL

      ok what i did
      i downloaded: https://distfiles.macports.org/MacPorts/MacPorts-2.3.1-10.9-Mavericks.pkg

      installed it
      then i opened a terminal and entered:

      xcode-select --install

      after that i entered:

      sudo port install qt5-mac-mysql56-plugin

      but i still get the same error :

      QSqlDatabase: QMYSQL driver not loaded
      QSqlDatabase: available drivers: QSQLITE QMYSQL QMYSQL3 QODBC QODBC3 QPSQL QPSQL7

      shall i do a

      sudo port install mysql56

      or

      sudo port install mysql56-server

      ??

        With that command you installed the Qt 5 version from macport. So you probably have also MySQL 5.6 already installed

          sorry sgaist - is that a question? i am not sure ?

          as mentioned before

          i have a debian server running mysql community server

          i got a macbook with QT 5.3.1 creator on it

          i want to open a connection from the macbook to the mysql community server on the debian server

          i am not sure if this is working ..

          maybe it is better to start from the beginning
          so which version of the QT 5 shall i download an install on my macbook ?

            @port installed | grep -i mysql@

            You'll see what MySQL package you installed.

            Probably located in /opt/local/lib/mysql56/mysql

              mysql_select @0.1.2_0 (active)
              qt5-mac-mysql56-plugin @5.3.1_0 (active)

              in /opt/local/lib/mysql56/mysql
              was:

              libmysqlclient.18.dylib
              libmysqlclient.a
              libmysqlclient.dylib
              libmysqlclient_r.18.dylib
              libmysqlclient_r.a

                So you have what is need. No the only thing is that your plugin point to mysql55 and not mysql56.

                Have a look at the install_name_tool command to change that in your plugin

                        It's an OS X command line tool

                        There are several posts on this forum that mention it on problem similar to yours

                            in a console write

                            @man install_name_tool@

                            Everything is explained

                              ok i gave up ..
                              i tried nearly everything that is suggested on :
                              http://stackoverflow.com/questions/6282889/install-name-tool-does-nothing
                              or
                              http://qt-project.org/doc/qt-5/macosx-deployment.html

                              i could not make it work with the install_name_tool

                              so i changed the name of the mysql56 to mysql55 in /opt/local/lib

                              it seemes to work now - i hope it gives no problems ..

                              thanks for help, B

                                Do you mean

                                @install_name_tool -change /opt/local/lib/mysql55/mysql/libmysqlclient.18.dylib
                                /opt/local/lib/mysql56/mysql/libmysqlclient.18.dylib libqsqlmysql.dylib@

                                Didn't work ?
