MOC don't generate slots that inside #if-#endif directives

[XelaG]

Hi,

I'm writing an app that runs on Windows and Android. Some functions are not available on Windows so I encapsulated them between #if..#endif directives.
@#if defined( Q_OS_ANDROID ) || defined( Q_OS_LINUX )
// Some code
#endif@

Some of my slots are encapsulated between those, and if use the following code to connect those slots, it doesn't work.
@connect( emitter, SIGNAL(signalToEmit(), receiver, SLOT(slotToConnect() )@

Qt says that the slot doesn't exist. Which is true, I checked the file generated by MOC and the slots are missing. I know I can use the following code but it doesn't work when there are some overloaded signals or slots.
@connect( emitter, &EmitterClass::signalToEmit, receiver, &ReceiverClass::slotToConnect )@

I tried to add DEFINES += Q_OS_ANDROID in the pro file but this generates errors at compilation time.
So what must I do to make sure MOC will see the code encapsulated between #if .. #endif directives.

Thanks.
Alex.
