        let me try to explain this now
        what i did is remove ubuntu and install fresh ubuntu. then i install qt creator at home/zafar/qtsdk-2010.05 directory. then i did this
        @
        sudo apt-get install libmysqlclient15-dev
        @
        then i ran
        @
        qmake
        @
        command as it is described on this link
        @
        http://prres.wordpress.com/2010/05/17/configure-mysql-database-driver-for-qt/
        @
        After executing qmake command it displays this message
        @
        the program qmake can be found in the following packages
        qt3-dev-tools
        qt4-qmake
        try sudo apt-get install <selected package>"
        @
        then i did "sudo apt-get install qt4-qmake" and it installs that package. then i run qmake command as describe in above link. it created Makefile in sqldrivers/mysql directory. everything went fine upto here but when i run make command it displays whole bunch of errors which i cannot type all those errors here.

          So you have wrong qmake maybe. Add path to home/zafar/qtsdk-2010.05/qt/bin to PATH env variable (at the begining of it of course) and run qmake again.

            ok i set variable by following steps here on "this link":http://www.zolved.com/synapse/view_content/28157/How_to_set_environment_variables_on_Ubuntu_

            now my variable is $QTVAR = /home/zafar/qtsdk-2010.05/qt/bin. now i should go to this directory and run qmake or something else.

              No, you've set the wrong env variable.
              @
              export PATH=/home/zafar/qtsdk-2010.05/qt/bin:$PATH
              @
              And after it run qmake in mysql plugin directory

                  Make itself outputs all steps of build. It shows you all compiling and linking operations it runs.

                  If make was successfull it should create libqmysql.so file which you should place into plugins/sqldrivers folder

                      Yes, all should be ok now. To check it just output content of
                      @
                      QSqlDatabase::drivers ()
                      @
                      QMYSQL should be there.

                          You can either do it via console (by running mysql command) or you can install apache+php+phpmyadmin for web interface or you can install one of desktop GUI mysql clients.

                              it depends on what server version do you have. You need client with same version.

                                whatever we did in this thread it did not install mysql server? it installs mysql driver for qt?

                                  Yes we've installed only driver for qt. If you want to store databases at your computer you need to install both mysql-server and mysql-client. If you will connect to remote database you can install only mysql-client.

                                    will it work if i install mysql server and client after installing mysql driver for qt? or if i install xamp then it will also work with qt. i am not using qt for web interface. i am using qt just to create desktop and mobile apps.

                                      Yes it should work. For better compatibility install client with exactly same version as your installed dev packages.

                                        how would i know the version of my installed dev packages(by dev packages you mean which i installed for qt now).

                                        and your reply "Yes it should work." means xamp will also work??

                                          You SHOULD have mysql-server to be able to store and work with mysql databases at your computer.
                                          Mysql-client is set of libraries and binaries which give access to mysql server (your or remote) for other applications or for you directly from console (mysql utility I'e mentioned before).
                                          As I've seen earlier in thread you've installed mysql dev packages for mysql 5.0, so you need to install server and client versioned 5.0.
