[mythtv-users] depmod and modprobe errors with pvr-250

[James Boike]

Folks,

Thanks for all your hard work with this project -- ivtv paired with 
MythTV made me a very recent Linux convert. Though I've searched through 
FAQs, docs, and various mail lists, I find myself stuck. I use Mandrake 
9.1, kernel 2.4.21, a PVR-250 rev2, and Myth 0.10 installed from Thac's 
RPMs. I posted a similar note to IVTV, but since I followed MythTV docs 
this list is probably more familiar with the situation.

I've followed Myth's mini-HowTo 
(http://mythtv.org/docs/mythtv-HOWTO-19.html#ss19.10) and successfully 
finished each step up to the depmod -a command from within 
~/ivtv/ivtv/driver. Doing this renders:

[root at ____ driver]# depmod -a
depmod: *** Unresolved symbols in 
/lib/modules/2.4.21-0.13mdk/kernel/drivers/media/video/ivtv.o
depmod: *** Unresolved symbols in 
/lib/modules/2.4.21-0.13mdk/kernel/drivers/media/video/msp3400.o
depmod: *** Unresolved symbols in

depmod: *** Unresolved symbols in 
/lib/modules/2.4.21-0.13mdk/kernel/drivers/media/video/tveeprom.o

And the results of the next step: modprobe ivtv

IVTV list told me depmod just checks module dependencies, and that it's 
"only really a problem if the unresolved symbols happen on module load." 
This seems to be the case given the second output, so I assume I have a 
problem. I don't seem to have a /dev/v4l directory, though lspci -v 
successfully displays my Hauppauge card.

One note that I'm not sure is related: Myth 19.10 docs say I do not need 
to recompile my kernel, but IVTV readme says I have to get my kernel 
"patched and compiled with the v4l2 stuff." I don't seem to have v4l2 on 
my system, as there is no v4l or v4l2 directory in dev. Are these two 
instructions contradictory?

I apologize for the length, but I want to be as thorough as possible. 
I'm very new, trying to grasp all this and taking copious notes so I can 
publish a newbie's HowTo when complete. I appreciate any recommendations 
to get past depmod and modprobe -- the simpler and more basic, the better.

Thanks again for all your efforts,
Jamey
