Comment April 23/06: A kernel 2.6.12 wouldn't build the modules but 2.6.16 worked well. I would suggest cd /usr/src/linux before retrieving the mercurial patches - the scripts couldn't find the kernel headers otherwise.
Apr 2007:
After following the steps above and getting down all needed sources I get the following output does this mean this driver does support 64bit kernels?
root@1[v4l-dvb]# make make -C /usr/local/src/v4l-dvb/v4l make[1]: Entering directory `/usr/local/src/v4l-dvb/v4l' scripts/make_makefile.pl No version yet.

Kernel 2.6.17 Compilation Errors
If compilation fails on v4l-dvb/v4l/dvb_net.c with errors (kernel 2.6.17):
error: 'struct net_device' has no member named 'xmit_lock'
Then edit the v4l-dvb/v4l/dvb_net.c file, go to the error lines and replace this text:
#if LINUX_VERSION_CODE < KERNEL_VERSION(2,6,18)
by this one:
#if LINUX_VERSION_CODE < KERNEL_VERSION(2,6,17)
The compilation should now continue.
I get a bunch of conflicts when I tried to do this. I run a custom 2.6 kernel, built from 2.6.18. I don't understand how the V4L tree jibes with the drivers from the kernel source. I suspect that if you are going to install drivers from a V4L tree, you should *not* configure the modules in the kernel tree (which modules should you not configure?).
There seems to be a big gap in the howtos, between those for newbies who have never set up any dvb card for linux, and those intended for developers.

I need help! I'm getting the issue as stated at the bottom of the page (more errata was it?). I can follow the instructions given but I dont have all of the paths/folders as described and dont know enough to help myself.
I the v4l-dvb package is in my home directory. I get the message saying "file not found: /lib/modules/2.6.22-14-server/build/.config" I dont have a folder called "build" at this path (or anywhere else I can see) so dont expect the symbolic link instructions pasted below to work.
What information can I give so that you can help me? I'm using ubuntu server 7.10.
"If you see the issue above, it is because your symbolic link for /lib/modules/<kernel-version>/build is broken. Before running make, remove the link and create a new pointing to the right location.
For your example above,
rm /lib/modules/2.6.15-27-desktop64-smp/build ln -s /usr/src/kernels/2.6.15-27-desktop64-smp/build /lib/modules/2.6.15-27-desktop64-smp/build"
