(OT) QThread, does it work?

[Tobias Erbsland]

I had tried not for 2 hours compile a small project with a QThread class:

class ServerThread : public QThread
{
  public:
    virtual void run();
}

But the liker failed every time, telling me her doesn't find 
"QThread::start()" etc...

I used the --enable-mt option with ./configure.

Hope someone can help me, i tried many things but nothing seems solve the 
problem.

(first i got the problem qith qt-2.2.4, now i switched to qt-2.3 with the 
same problems.)

regards
Tobias
