Hi,
Forgive me maybe lame question, but c++ isn't thing I know enough.
  
I want to share&amp;use global variable between all instances of dvbchannel objects.
My idea was to declare this variable as static in dvbchannel.h.
  
class DVBChannel : public DTVChannel
{
   public:
       static QDateTime   last_tuning;
  
It compiles, but unfortunately linker returns:
../../libs/libmythtv/libmythtv-0.27.so: undefined reference to `DVBChannel::last_tuning'  
  
So what is best way to declare global, shared variable used by all instances of dvbchannel ?
  
Thx in advance
