Hello,
I am really confused with QT for running demo. I have QT 3.2.1 open source 
edition and I installed it.

The first problem is:
1) when I try to run a demo it says that "qt-mt.lib" was not found. I 
searched for it and found that there is a file "qt-mtnc321.lib". I rename it 
to "qt-mt.lib" and it seemed that this error was gone. I am not sure whether 
I did the right thing or not!

After that, second problem raised.

2) when I tried to compile the demo again, the code compiled successfully but 
at linking section, error LNK 2005 was generated. I found it a complicated 
error and after lots of searched I realized that this error is generated 
because there are two files (I think object files) and both of them have unic 
function and they try to call it. I think the root of problem is some where 
in static or shared libraries and further researches showed that after I add 
cgalqt-vc71-mt-gd.lib to library folder, this awful error is generated.

I am not sure again whether I am right or not.

I have a philosophical theory and I really need a guide from authors.

If the QT is embedded to CGAL, so there is no need to have QT for running 
demos; else what is the role of "cgalqt-vc71-mt-gd.lib"?

if it is true, by disabling "#ifndef CGAL_USE_QT", the demo should run (but 
it does not).

if it is false, mean QT is not embedded to CGAL, so I must install QT and it 
seems that two files, one from CGAL libraries and one from QT libraries I 
have installed, conflict at a same function and lead to LNK 2005 error.


Hope I outlined the problem correctly, but in one sentence "I get error LNK 
2005 in linking section of compilation process".


Really need a guide...
