When trying to upgrade to svn on R5F27 my configure script kept telling me that it could not find the dvb headers, and that ivtv/v4l support would not be included. Looking into the headers folders in /usr/src/ I noticed that the the DVB, IVTV, and V4L headers were all sym links to files in the /root directory that are not there on a default install. Is there anyway to fix this, as I am not too experienced with playing with kernel headers. Thanks!

Get the "tip" from linuxtv.org and make kernel-links.

greend139 I seem to be having the same problem. Did you get this to work, and if so what steps did you take?

It worked for me. Follow the instructions at http://linuxtv.org/repo/ for getting the latest v4l-dvb source (the "tip"). Once you download/unzip/un-tar the tarball, go into the directory that it created and as cecil said make kernel-links.

did you have to make and make install in the v4l-dvb directory or just create the links?

Just Code: make kernel-links.
All you are doing is creating symbolic links from the downloaded header files to the directory that the mythtv makefiles are expecting them to be. You don't need to compile anything. (Except for the mythtv source!)

Sounds like the Makefile is trying to guess where your kernel directory is and it is guessing wrong. My /lib/modules/2.6.18-chw-13/build is symlink'ed to /usr/src/linux-headers-2.6.18-chw-13. Is your directory structure different for some reason? Maybe if you linked /lib/modules/2.6.18-chw-13/source to /usr/src/linux-headers-2.6.18-chw-13 it would work.

I just downloaded the src tree from linuxtv and did make kernel-links (as root). Doing a make install really screwed a few things up, so i recommend not doing it. After make kernel-links i am able to build mythtv from svn head with dvb & ivtv support without any problems.

I see they are linking to
ivtvfb.h -> /root/v4l-dvb-1387dc197077/linux/include/linux/
and there for im getting this version
http://linuxtv.org/hg/v4l-dvb/rev/1387dc197077
works for me
I tried the newer verison and got all kinds of errors, since that is not the same headers.

I'm confused, because TJC told us in his R5F27 Tips http://mysettopbox.tv/phpBB2/viewtopic.php?t=16384
that the headers are included with a default install??
Quote: 7.2) The full kernel source is no longer included, however, the kernel headers needed to compile modules are. I have personally compiled both ivtv and nVidia drivers using these.
After reading of version conflicts above, I followed haffi's method and downloaded the same version:
http://linuxtv.org/hg/v4l-dvb/rev/1387dc197077
I think the 'make kernel-links' worked. Here's the output to review:
Code: root@mythtv:/usr/src/v4l-dvb-1387dc197077# make kernel-links
make -C /usr/src/v4l-dvb-1387dc197077/v4l kernel-links
make[1]: Entering directory `/usr/src/v4l-dvb-1387dc197077/v4l'

install --mode=u=rwx,go=rx chopatscfile dtvsignal dtvscan dtvsnr getatsc atscpackets /usr/bin
root@mythtv:/usr/src/dvb-atsc-tools-1.0.7#
Are there other software packages or modules that will require users to "make kernel-links" for?
Insight appreciated,
Eric

If you search around a bit, you will see that these missing headers have been required for quite a few different purposes. I can't remember all of them, but luckily you now have them. I think their absence is just an unfortunate oversight judging by cecil's comment from http://www.knoppmyth.net/phpBB2/viewtopic.php?p=104432#104432
