#error "The header file 'xqtelephony.h' doesn't include <QObject>."

Hello friends...

while building my application I am getting an error like:

[QUOTE]C:\QtProjects\Events\moc\moc_xqtelephony.cpp:12: #error "The header file 'xqtelephony.h' doesn't include <QObject>."
ERROR: cpp.EXE failure[/QUOTE]

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.

Thanks...

And how does line 12 of moc_xqtelephony.cpp looks like?

I don't have sources, but it seems it wants #include <QObject> in the xqtelephony.h

divanov, the file has #include <QObject>
please check the contents:

Same question. I use N8 to run my program and moc as below. what's this suppose to mean?

#error "The header file 'clock.h' doesn't include <QObject>."
#elif Q_MOC_OUTPUT_REVISION != 62
#error "This file was generated using the moc from 4.6.3. It"
#error "cannot be used with the include files from this version of Qt."
#error "(The moc has changed too much.)"

Clearly, the version of QObject being included doesn't define Q_MOC_OUTPUT_REVISION. It may well be that QObject is erroring somehow in the include step, or that there's another define (or not) that's sending QObject down the wrong #ifdef path.

This error usually occurs when you try to compile the MOC-generated file as a regular source/header file. For example, having something like
[code]
SOURCES += *.cpp
HEADERS += *.h
[/code]
will easily lead in to such problems unless you have MOC_DIR pointing to some other directory.
