[linux-dvb] Module modprobing problem

[Stefano Sabatini]

Hi all,

I'm trying the latest v4l-dvb mercurial and this is the output I get:

stefano@geppetto ~> sudo modprobe dib7000m -v
insmod /lib/modules/2.6.22-3-486/kernel/drivers/media/dvb/frontends/dibx000_common.ko 
WARNING: Error inserting dibx000_common (/lib/modules/2.6.22-3-486/kernel/drivers/media/dvb/frontends/dibx000_common.ko): Invalid module format
insmod /lib/modules/2.6.22-3-486/kernel/drivers/media/dvb/frontends/dib7000m.ko 
FATAL: Error inserting dib7000m (/lib/modules/2.6.22-3-486/kernel/drivers/media/dvb/frontends/dib7000m.ko): Invalid module format

stefano@geppetto ~> uname -a
Linux geppetto 2.6.22-3-486 #1 Mon Nov 12 07:53:08 UTC 2007 i686 GNU/Linux

I get in dmesg:
dibx000_common: disagrees about version of symbol struct_module
dib7000m: disagrees about version of symbol struct_module

Any hint will be highly appreciated.

Regards.

For the archive: the problem was due to the linux headers used when
compiling don't match the effective kernel version. In my case (Debian
system) I had installed linux-headers-2.6.22-3 and running a kernel
2.6.22-2, that was apparently sufficient to get a version symbol
mismatch.

Updated kernel and headers to 2.6.26 and now I can compile and
modprobe them safely.

Regards.
