Public bug reported:
when trying to use qtsql in (x)ubuntu precise (12.04), it fails to do
anything since no sql drivers are loaded and prints the following error
on the console:
> QSqlDatabase: QMYSQL driver not loaded
> QSqlDatabase: available drivers:
i've checked qt's library paths (QCoreApplication::libraryPaths()) and
it turns out, the path to qt's dynamically loaded sql drivers is not on
the paths list:
"/usr/lib/kde4/plugins"
"/some/path/to/the/executables/working/directory"
when i add
/usr/lib/x86_64-linux-gnu/qt4/plugins
as additional library path, then QSqlDatabase::drivers() correctly finds
the sql plugin drivers and returns
"QSQLITE"
"QMYSQL"
"QMYSQL3"
