[mythtv-users] Compiling Mythtv with DVB...

Hi Folks,

Having a slight problem atm with my MythTV 0.16 installation.  Its been 
working perfectly, 1xTT-DVB-T card, 1xPVR250 and a second backend with a 
BT878 card.

Anyway, I decided to switch fully over to DVB-T for all my tuners, and 
purchased 2 Nova-T cards.  Now, as some may know, the new cards are 
based on the Conexant chipset, and is very difficult to get going - took 
me 4 days of trying various kernels, drivers etc.

They are now installed, and working fine, along with my original DVB-T 
card - the 2 other cards are no longer in the system.

I am now trying to compile mythtv on the master backend.  During 
compilation, I get this error:

make[2]: Entering directory `/root/build/mythtv-0.16/libs/libmythtv'

make[1]: *** [sub-libmythtv] Error 2
make[1]: Leaving directory `/root/build/mythtv-0.16/libs'
make: *** [sub-libs] Error 2

I have setup the settings.pro as follows:

# DVB support
CONFIG += using_dvb
DEFINES += USING_DVB
# Note: INCLUDEPATH should point to the directory with
#   'linux/dvb/frontend.h', not the directory with frontend.h
INCLUDEPATH += /root/build/dvb

and as per Martin Smith's excellant guide (thanks Martin) have copied 
the include files from the kernel dvb driver to the /root/build/dvb.

Googling doesn't reveal anything, nor does searching the list.  Can 
anyone help?

Thanks,

Richie
