Hello friends...

while building my application I am getting an error like:

C:\QtProjects\Events\moc\moc_xqtelephony.cpp:12: #error "The header file 'xqtelephony.h' doesn't include <QObject>."
ERROR: cpp.EXE failure
In my Windows XP machine, it's running fine, how ever on my Windows 7 machine I got this kind of error.

I am using "Mobile_extensions_preview_3" for my telephony usage.

Any Idea how to remove this error.
