[SOLVED]QT5 unable to build MySQL driver under ubuntu


  • 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
    usename@usename-pc ~ $ make install@

  • 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”@
