installing ivtv, pvr-350, mandrake 9.1, unresolved symbols during depmod -a HELLLP!!
|
|
MythTV brothers,
I'm trying to install the ivtv drivers for my pvr-350
on a Mandrake 9.1 system. I'll describe step by step
what I did, and hopefully someone can tell me what I
did wrong, and maybe other readers will find this
informative.
I started by following section 19.1 of the MythTV faq:
----------------
In the FAQ:
$ uname -a
Linux pvr 2.4.21-0.16mdk #1 Fri Apr 11 06:51:54 CEST
2003 i686 unknown
unknown GNU/Linux
$ su
# urpmi kernel-source
----------------
So I typed 'uname -a'. The result was pretty much the
same, except my version number is 2.4.21-0.13mdk #1
Fri Mar 14 15:08:06 EST 2003 i686. I'm not sure if
this makes a difference.
Then I entered superuser mode and downloaded the
kernel-source. After like 10-15 minutes of
downloading, this step completed without a hitch.
The downloaded kernel source was a newer version than
the kernel I'm running, but the FAQ says "NOTE: You do
not need to recompile your kernel."
Then I executed:
$ cvs
-d:pserver:anonymous [at] cvs:/cvsroot/ivtv
login
<enter> as password
$ cvs -z3
-d:pserver:anonymous [at] cvs:/cvsroot/ivtv
co ivtv
This part seemed ok.
Then, instead of
$ cd ivtv/ivtv/utils
$ wget
http://hauppauge.lightpath.net/software/pvr250/pvr250_16_21062.exe
$ su
# ./ivtvfwextract.pl pvr250_16_21062.exe
I went to the hauppauge website using a browser and
downloaded the pvr250_16_21062.exe file. I ran
ivtvfwextract on it and this created two files,
lib/modules/ivtv-fw-dec.bin, and
lib/modules/ivtv-fw-enc.bin. Seems fine and dandy.
Then, I did this:
$ cd ~/ivtv/ivtv/driver
$ make
Everything looked good. I now had a bunch of .o files.
I added the required lines to /etc/modules.conf, and
then ran
$ su
# make install
This copied a bunch of .o files into
/lib/modules/2.4.21-0.13mdk/kernel/drivers/media/video/
Next, I did an extra step not covered in the mythTV
FAQ. In the ivtv FAQ found at
http://ivtv.sourceforge.net/FAQ.html#_jump08,
"V4L2 headers are required for ivyTV to compile. You
can either patch your kernel with v4l2 headers or copy
the included videodev2.h from the utils/ directory to
the driver/ directory." So I copied the videodev2.h
file like the FAQ stated.
Then when I did
# depmod -a
I got:
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
/lib/modules/2.4.21-0.13mdk/kernel/drivers/media/video/saa7115.o
depmod: *** Unresolved symbols in
/lib/modules/2.4.21-0.13mdk/kernel/drivers/media/video/saa7127.o
depmod: *** Unresolved symbols in
/lib/modules/2.4.21-0.13mdk/kernel/drivers/media/video/tveeprom.o
This is where I have the shake my head and say I have
no idea what is going on.
I went ahead and did
# modprobe ivtv
but the driver modules failed to load.
If someone could please please help me with this, I
would be much obliged! I've been stuck on this for a
whole day already.
This mail was probably more verbose than necessary,
but hopefully someone just starting the mythTV project
will find my lengthy descriptions helpful. If you guys
want me to tone it down, just tell me =).
