I have similar problem with MYSQL driver. From my app I get "Driver not loaded.". From QQSqlDatabase for availabe drivers I get: "QSQLITE QMYSQL3 QMYSQL QODBC3 QODBC". I've built plugin according to QtCentre's Wiki. I've copied qmysql.dll into qt's bin dir, which IS IN PATH. I have also added "+=SQL" into .pro file. What else can be wrong or what am I missing, please help!
