Code:
 localhost linux-2.6.20.6 # make all && make modules_install
scripts/kconfig/conf -s arch/x86_64/Kconfig
  CHK     include/linux/version.h
  CHK     include/linux/utsrelease.h
  CC      arch/x86_64/kernel/asm-offsets.s
arch/x86_64/kernel/asm-offsets.c:1: error: code model 'kernel' not supported in the 32 bit mode
arch/x86_64/kernel/asm-offsets.c:1: sorry, unimplemented: 64-bit mode not compiled in
make[1]: *** [arch/x86_64/kernel/asm-offsets.s] Error 1
make: *** [prepare0] Error 2


i used instructions here: http://wiki.awkwardtv.org/wiki/Linux_on_Apple_TV

i get that error when i try to make the kernel, this is what i have done leading to it:
Code:
 
cd /usr/src
tar -xjvf linux-2.6.20.6.tar.bz2 -OR- tar -zxvf linux-2.6.20.6.tar.gz
emerge subversion
svn co https://mactel-linux.svn.sourceforge.net/svnroot/mactel-linux/trunk/mach_linux_boot/kernel .
patch -p0 < 2.6.20.6-appletv.patch
mv config-2.6.20-appletv linux-2.6.20.6/.config
cd linux-2.6.20.6
make && make modules_install


the system i am chrooting into the appletv HD is an amd64. i think it has to do with difference in my current system and the chrooting environment with regards to 32 vs 64 bit but i cannot figure out how to solve problem.

Whenever you have a compilation failure, you should post the output of emerge --info, or a link to a post where you recently provided it.

You cannot use an x86 native compiler to build an amd64 kernel. You must use a cross-compiler, or switch to a native amd64 compiler. The latter requires that your host system be able to run amd64 binaries.

thank you
Code:
 linux32 chroot /mnt/gentoo /bin/bash

solved the problem. i think that would be the cross compiling you mentioned.
