building v4l-dvb - compilation error

building v4l-dvb - compilation error

[Karicheri, Muralidharan]

Hi,

I have installed mercurial and cloned the v4l-dvb tree. I tried doing a build as per instructions and I get the following error. Since I am in the process of validating my build environment, I am not sure if the following is a genuine build error or due to my environment...

Other questions I have are:-

1) I am just doing make. So does this build all v4l2 drivers?
2) Which target this build for?
3) What output this build create?

Yes.

The one found on your running. You may force a different target with
	make ARCH=<some_arch>

The *.ko modules.

The minimum supported version by the backport is 2.6.16.


Cheers,

Mauro,

I ran the build using my ubunto linux box at home and it has succeeded
the build.

Hmm. Does that means, the build is using the kernel source code
natively available at /usr/src/kernel. Is there a way to force it use
a specific kernel source code?

Yes:
	make release DIR=<some dir>

After that, all subsequent compilations will use the new dir, provided
that you don't do a make distclean.
