using dpkg-buildpackage to compile a kernel

[David Madore <david.madore@ens.fr>]

Hi.

I'm trying to compile a Debian kernel package from "unstable" (on a
"testing" system) using dpkg-buildpackage, with a few minor changes to
the config file.  I've upgraded a few packages (such as kernel-package
and dh-kpatches) to "unstable", so testing should not be the problem.

I run "apt-get source linux-image-2.6.12-1-686-smp", I edit the
debian/changelog file slightly and the config file
debian/arch/i386/config as needed.  I also needed to change the modes
of the files in debian/bin because for some reason they were not
marked as executable (why is that???).

After this I try "dpkg-buildconfig -rfakeroot" from the base source
directory, and the following occurs:

gloin david /tmp/linux-2.6-2.6.12 $ dpkg-buildpackage -rfakeroot
dpkg-buildpackage: source package is linux-2.6
dpkg-buildpackage: source version is 2.6.12-5a

This target is made to fail intentionally, to make sure
that it is NEVER run during the automated build. Please
ignore the following error, the debian/control file has
been generated SUCCESSFULLY.

exit 1
make[1]: *** [debian/control-real] Error 1
make[1]: Leaving directory `/tmp/linux-2.6-2.6.12'
make: *** [debian/control] Error 2

I don't understand at all what this error means.  How am I supposed to
build this package?  What is wrong, here?

A pointer to any kind of HOWTO or clear documentation would be
welcome.
