      I want to build QMYSQL plug-in for MySQL driver under ubuntu but I got this error message:

      bq. mbnoimi-pc mysql # qmake "INCLUDEPATH+=/usr/local/include" "LIBS+=-L/usr/local/lib -lmysqlclient_r" mysql.pro
      WARNING: /opt/Qt5.0.1/5.0.1/Src/qtbase/src/plugins/sqldrivers/qsqldriverbase.pri:4: Unable to find file for inclusion qt_plugin
      Project MESSAGE: Warning: unknown QT: sql-private

      How can I fix this issue?

      PS

      I've installed libmysqlclient-dev, libmysql++-dev packages

        I believe this is matter of error paths I tried to use the following but it didn't work:

        bq. qmake "INCLUDEPATH+=/usr/include/mysql" "LIBS+=-L/usr/lib/x86_64-linux-gnu -lmysqlclient_r" mysql.pro

        PS

        I forgot to tell you that I'm using ubuntu 12.10 x64

          The solution of this issue is by calling qmake as absolute path because it was using Qt4's qmake.

                  The system show you that you havn't Qt plugin for MySQL (you have SQLite) so try to build your own Qt MySQL plugin from https://qt-project.org/doc/qt-5.0/qtsql/sql-driver.html#qmysql

                  PS
                  I suppose you're using Qt5

                                OK, try to do the following (considering installation directory is /home/usename/Qt5.0.2):

                                @usename@usename-pc ~ $ sudo apt-get install tasksel
                                usename@usename-pc ~ $ sudo tasksel install LAMP
                                usename@usename-pc ~ $ sudo tasksel install libmysqlclient-dev
                                usename@usename-pc ~ $ cd /home/usename/Qt5.0.2/5.0.2/Src/qtbase/src/plugins/sqldrivers/mysql
                                usename@usename-pc ~ $ /home/usename/Qt5.0.2/5.0.2/gcc_64/bin/qmake "INCLUDEPATH+=/usr/include/mysql" "LIBS+=-L/usr/lib/x86_64-linux-gnu -lmysqlclient_r" mysql.pro

                                usename@usename-pc ~ $ make install@

                                    First of all, Could you please put the log inside code format.

                                    give me the output of the following:
                                    @cd ~
                                    find ./ -name "mysql.pro"@

                                        It seems that you didn't install Qt into your home directory. Try to run find where Qt installed.

                                            Try to download recent Qt installer (currently 5.0.2) , through installation wizard choose all available components (it has Qt' source code). Then:

                                            @cd ~
                                            find ./ -name “mysql.pro”@
