compile problem when QThread used

Hello,
I made Qtopia GUI application. It runs OK. It uses various Qt classes like
QTimer, QDateTime etc. 

But when I try to include QThread object the compilation fails with:

In file included from ikh_main_form_imp.cpp:1:
./ikh_main_form_imp.h:36: error: 'QThread' does not name a type

In the implementaion header I add:

#include <qthread.h>   //no complains from compiler about this file

  QThread rxThread; //but when added this line compilation fails.

In qte 2.2.0 is no thread support. Take a look in qthread.h:
#if defined(QT_THREAD_SUPPORT)
it's not defined. 
If you need something like a thread use QTimer or fork.
For many short jobs like polling a input device QTimer is a good choice, 
for a more time consuming task i would prefere fork.

skip

Thank you.
