undefined reference to `vtable" proble

Message 1 in thread

Hi,
I started developing my application on qtopia using qt designer.
I have little problem while compiling my application.I used signals and
slots from qtdesigner and it is giving some problem.
I created implementation file and inherited the class creted by QT designer.
i created the same slot which is there in the base class as virtual
function. Every thing i did fine. but it is not compiling. I am using suse
10.0. as my os. If i won't create implementation file and  if compile it is
compiling fine.
I am attaching my application also for ur refernce.

When i did make it is giving following message.

Thanks in Advance.

You need to fix your .pro file. Every header file that contains a  
Q_OBJECT macros should be listed in HEADERS, generally you should  
list all HEADERS to enable dependency tracking.

Hi Holger
Thanks for Ur reply.
I modified my *.pro file as fallows.
/******** pro file **********/
TEMPLATE = app
INCLUDEPATH += .

# Input
INTERFACES += ANSiscope_PatientInfo.ui Main_Processing.ui
SOURCES += ANSiscope.cpp  ANSiscope_PatientInfoImpl.cpp

HEADERS = ANSiscope_PatientInfoImpl.h ANSiscope_PatientInfo.h  \
          Main_Processing.h
TARGET = CANSiscope

/******************* **************/


Then I run qmake to create make file
It has given following warnings.

Then If i run make

Do not add autogenerated files to HEADERS/SOURCES.
