[mythtv] [PATCH] DBOX2 Feed Implementation 2005-05-10

Mon May 30 12:18:54 UTC 2005

Guys I can't even get this to compile with todays cvs
on fedora core 3

In file included from tv_rec.cpp:47:
dbox2recorder.h:41: warning: direct base `QObject'
inaccessible in `DBox2Recorder' due to ambiguity
dbox2recorder.h: In member function `QObject*
DBox2Recorder::qObject()':
dbox2recorder.h:42: error: `QObject' is an ambiguous
base of `DBox2Recorder'
tv_rec.cpp: In member function `bool TVRec::Init()':
tv_rec.cpp:155: error: cannot allocate an object of
type `DBox2Channel'
tv_rec.cpp:155: error:   because the following virtual
functions are abstract:
channelbase.h:61: error:  virtual int
ChannelBase::GetFd()
make[2]: *** [tv_rec.o] Error 1

make[1]: *** [sub-libmythtv] Error 2
make[1]: Leaving directory

I'm using fedora core 3 and the latest updated patch

Do you have any ideas?
