[mythtv-users] hdpvr.ko unknown symbol (compiling from linuxtv.org)

[Michelle Dupuis]

I tried compiling the latest hdpvr drivers from linuxtv.org (as per the mythtv wiki).  Although it compiles, loading the hdpvr module gives the error below (which corresponds with an error during make).  Is this a problem or can I ignore it?

in the v4l/.config I set all modules to 'n' except the lirc_zilog and hdpvr modules which I want.  Is this related?  I see the unknown symbol __video_register_device defined in v4l2-dev.c but not sure why that's not being compiled/used.  I want to avoid a massive upgrade to my kernel modules, so I'm trying to compile as little as possible/needed.

Thanks!
