In your earlier posting you wrote "Just leaving out the --subarch
seems to work." If this means you already compiled successfully one
kernel without a flag like that then I'd omit the "--arch" option:
I don't remember having *ever* used this option for a, admittedly,
non-ppc64, but ppc kernel. IIRC gcc automatically detects the
architecture of a computer and then compiles accordingly ....
I'd keep things as simple as possible: every extra flag might become
the source of a fail, so if I don't need it I'll scrap it ... :)
Furthermore: Instead of doing something like a
"make-kpkg --config oldconfig"
I'd do a plain old "make oldconfig" or "make config" or "make
menuconfig" etc. instead:
This way one can safely stop editing the .config for a new kernel, and
then continue later on, after having saved the changes to the
.config; the option for the latter could be very convenient because
doing a kernel .config can become a time consuming task (easily a
dozen or more hours if it's one's first config)
One of my favorites: /usr/share/doc/kernel-package/README.gz
To read files like the latter with 'less', and without the need to
unzip them simply put something like this into your bashrc (Don't ask
me about the "lesspipe %s" flag: I don't know exactly what it
means (Anyone out there who does ...? .. :)). It just works for the automatic unzip stuff... :) .. :
export LESSOPEN LESSCHARSET LESS
After editing the kernel .config, something like this:
MAKEFLAGS="CC=gcc-4.0" fakeroot make-kpkg --append-to-version=-special-name --revision whatever kernel_image
Replace "whatever" and "-special-name" with names you want. And the
command above does not create an initrd image, IINM ....
Are you sure you need initrd? I live happily without it on a 2.6
kernel, since quite some time ... :)
What did I miss? ... :) .... Anyone? ...
