Hi,
I have found a workaround for the problem. I have included the
BonjourRecord header because it doesn't have any dependency on
dns_sd.h. This way I can safely declare the slots on the header. The
main problem here is that the moc_ doesn't know about Q_OS_ANDROID when
it is generated which will generate entry for the slots that shouldn't
be there.
public slots:
#ifndef Q_OS_ANDROID
void recordAdded(const BonjourRecord &record);
void recordRemoved(const BonjourRecord &record);
void bonjourRecordResolved(const QHostInfo &hostInfo, int port);
#endif
Anyway, as you requested, this is the complete output of the error:

Could you please send the exact error you're having? I'm interested in
who's complaining exactly about what.
It shouldn't be moc -- moc can't care less about who implements some
slots. It could be the compiler (if you're defining member functions
without declaring them, that is, you're missing the matching #ifndef
in your .cpp files), or the linker (which would possibly mean that moc
picked up those member functions and it's referencing them, but their
symbols are not present in any object file)...
Thanks,
