RE: somebody help me!

Because Qt database driver needs the client's library to operate on a database. That's exactly the same with other drivers too.

I don't exactly understand what you mean... You mean that the compiler links the project even if there is no client library on your system? Of course it does, because it is the driver that depends on it and not your application directly. You can build it, but you won't be able to run it probably.

No I can't. I don't use crap like that

You have forum for asking questions. You can also ask Qt related questions on #qt channel at irc.freenode.org

See this thread:
http://www.qtforum.org/thread.php?threadid=11240

File plugins/src/sqldrivers/README reads:

Quoted

Please note that the Oracle and TDS client drivers are not distributed with
the free version of Qt.

This is because the client libraries are distributed under a license which
is not compatible with the GPL license.

You must have all libs your program and its dependencies depend on. Google for more info on how to check dependencies of a program.

Don't look for anything on Google for now.
Just answer this question first:
Which exact version of Qt are you using?

OK, if you have Qt 3.2.0 Enterprise edition, you need to:

Get the Oracle client libraries from Oracle;
Build the Oracle driver as described in the Qt documentation - the Trolltech Web server is down so I'm afraid I can't provide an URL.
[/list=1]

So yes, you need to install the Oracle client libraries in order to build the Qt Oracle drivers.
