[Qt-embedded-interest] problems in configuring 'qvfb'

Tue Mar 31 12:36:02 CEST 2009

Sorry if I sound rude but the intention is not that. Its really turning out
to be a
Introduction to Unix builds kind of a chain which is not what this forum is
for.
Avishek, I would really recommend that you first get yourself acquainted
with how a normal Unix build happens. Once you get a hang of that, Qt builds
will happen automatically. There is not specific about Qt builds vis-a-vis a
generic C++ build on Unix.

In any case if you guys still want to keep the chain moving, please take it
offline as its adding no value to the qt embedded forum to learn how to
specify link libraries in a unix build.

Thanks for understanding and no offence meant against anybody,
Pankaj
