Thanks for that.
This version "breaks" my Visual Studio test app (it crashes upon calling 
dbopen).
I think it's exactly the same behaviour I was getting...

I'm afraid it also doesn't work at all from Qt.
It's like it doesn't understand at all these libraries.
Are you really supposed to share libraries between compilers? I'm sure I had 
read somewhere that this is something that cannot be done (different formats).

My build output is the following:
