A separate one from both the extension modules? Are both extension

Sure. It is the Qt library. 

No.


Hmm, now I am confused.

Yes, that's part of why you put the base class in a common shared

Well, Qt libraries are seen by all modules. The modules itself that don't 
see each other. 

This is a pretty murky area for the Gnu loader, unfortunately.

Well, if it is only a g++ problem on the Gnu system, I can use the 
"setdlopenflags" workaround. I just have not tested on other systems like 
Windows. Looks like that it will work there.
