    Hello,

    I recently installed Qt5.5 on a new machine with Ubuntu14.04 amd64 but I cannot load the mysql driver for my application. It is available but not loaded.
    "QSqlDatabase: QMYSQL driver not loaded
    QSqlDatabase: available drivers: QSQLITE QMYSQL QMYSQL3 QPSQL QPSQL7"

    I used the following way to build the plugin:
    http://doc.qt.io/qt-5/sql-driver.html#qmysql

    Which worked without any errors, on my older machine I used Qt5.2 (or 5.1 not sure), anyway after that I had to create a symlink to load the driver "sudo ln -s x86_64-linux-gnu/libmysqlclient_r.so libmysqlclient_r.so.16" in /usr/lib

    using ldd in the plugin directory gives the following output:
    linux-vdso.so.1 => (0x00007fff597fe000)
    libmysqlclient.so.18 => /usr/lib/x86_64-linux-gnu/libmysqlclient.so.18 (0x00007f872309a000)
