Thanks Freddy, I can now use more of the program I am developing with Qt on 
Linux using your driver.

I know it is early days for WCHAR support, but my prepared queries now run.

However I do get a problem when multiple queries are running at the same 
time. 
The data gets mixed up between the queries when populating my tables. If I 
run 
the queries sequentially one after the other completes I do not get this 
problem.

If you need me to do any debugging for you just ask.

Thanks for your hard work,
Royce
