Package request: media-build for new/updated ATSC/DVB drivers

[Carl Michal]

One issue with the 3.14 kernel in the Cubox-i Geexbox distribution is that it's getting harder and harder to find ATSC tuner dongles that are supported. Apparently though, there is a straightforward way to backport newer drivers to older kernels using the media-build repo here:

http://git.linuxtv.org/media_build.git

There are some build instructions here:
http://nucblog.net/2014/11/installing-media-build-drivers-for-additional-tv-tuner-support-in-linux/

Is it conceivable that this could be packaged for the cubox-i Geexbox?

Thanks,

Carl

I tried this quite a while ago. But I gave up because it was too complicated to
integrate into our cross compile environment. At least with the skills I had back
then. When I remember correctly, it heavily relies on the assumption that it is
run on the same machine for which the driver is to be built...

Thanks for the response. I had a quick look through the build script and I think I see what you mean. I may put some time into it. Is there a beginners guide to adding packages to openbricks somewhere?

You can look here :
http://www.openbricks.org/docs/openbricks-manual.pdf
Maybe the best way is to look how others packages are made too ;)

I haven't looked at all at packaging at all, but it looks like what is required to build this is:
prereqs: hg, lsdiff (patchutils), wget, Digest::SHA, Proc::ProcessTable
Then:
hg clone http://linuxtv.org/hg/~endriss/media_build_experimental#ada40c8874d5
cd media_build_experimental
make download
make untar
VER=3.14.14 OUTDIR=/path/to/linux-3.14.14/ SRCDIR=/path/to/linux-3.14.14 make

This is borrowed from a Gentoo ebuild. It bypasses the media-build "build" script, which looks like a lot of effort to ensure the prereqs are installed and give hints on how to install them for various distributions. This picks a version of media-build from 2015-05-09, which isn't up to the minute, but it does compile against 3.14. There may yet be some gotchas in there.
