[maemo-developers] [maemo-developers] Error compiling kernel

[From: Andrey Khurri]

Hi all,

I made modifications to n770_defconfig according to Maemo HowTo: 
http://maemo.org/maemowiki/HowTo_KernelCompilation
Then after running "dpkg-buildpackage -rfakeroot -uc -us -sa -D" or 
"dpkg-buildpackage -rfakeroot -uc -us -sa -d" (I tried both ways) I get 
following error:

I did modifications to debian/rules exactly how HowTo suggests it, that 
is I commented 2 lines out.
I have looked trough mailing list archive but I didn't find any similar 
to mine bugs.

By the way, what would be the right/perfect way of modifying 
n770_defconfig file?
I did it as follows: copied to a kernel source tree on my host PC, ran 
"make menuconfig" there, made modifications I need, replaced old config 
with new one in arch/arm/configs (of course, with the same name 
"n770_defconfig").
I also tried to run "make n770_defconfig" inside 
../build/su-18-kernel-2.6.12.3/kernel-source-2.6.12.3 . However, it 
doesn't seem to be working properly. It just goes trough the config file 
and outputs its content up to a point but it doesn't proceed with usual 
graphical interface where you choose options.

I am wondering if someone has experienced the same. I would appreciate 
any help or comments.
Thanks in advance.

Andrey
