[Qt-interest] Static linking

[JD Guzman]

Hello Srdjan,

I don't post here often but follow the list closely as many times issues 
that are addressed are of help to me later.

All I can say about this person posting is that from what I have seen he 
is developing a commercial application and want the list readers to hand 
him all the answers on a silver platter.

Sujan I would recommend that you read the Qt docs as most if not all of 
your questions are addressed in there.  Also what you don't find in the 
Qt docs I would recommend that you do a thorough google search as the 
answer is probably out there already.  If all else fails ask the list.  
Asking is fine but sometimes it seems that you are under the impression 
that the list has to answer.

Cheers,

JD
