[Qt-interest] subclassing Sql drivers

[Andre Somers]

Hi,

I am trying to extend the Qt SQL drivers to add some functionality. I 
have the thing compiling, but I run into a problem when linking. I get 
lots of "undefined reference" errors like these:

C:/projects/srtools/common/ExtendedDatabaseDrivers/accessdriver.cpp:124: 
undefined reference to `QODBCDriver::open(QString const&, QString 
const&, QString const&, QString const&, int, QString const&)'

for all the methods that I subclassed (or are done so by moc). Yes, I 
have included the Q_OBJECT macro.

This particular driver is trying to extend the QODBCDriver to specialize 
it for using with Microsoft Access. T
The issue *seems* to be that if I include the sql module, I am not there 
yet. I guess I have to link to the driver lib itself in some way, but I 
don't really see how. However, I may be off the mark.

Any hints are appreciated.
