I'm trying to build an x66-64 kernel on a 32 bit system (Ubuntu 5.10).
I added -m64 to the CFLAGS as per the gcc docs.  But the build fails
with:

$ make ARCH=x86_64
[...]
CC      init/initramfs.o



I have successfully done this using Debian/Sid.



I added "-m64" to AFLAGS as well and now I get farther:

Yes, some commands NEED the -m64 and and WILL NOT work with -m64.
Really, try my method. I've done it without all that making a separate binutils non-sense. You do need the 64-bit Debian build tools and 64 bit libraries. These are the ones I have: 

amd64-libs
amd64-libs-dev
lib64gcc1
lib64gfortran0
lib64ncurses5
lib64ncurses5-dev
lib64objc1
lib64stdc++6
lib64stdc++6-4.0-dbg
lib64z1
lib64z1-dev
libc6-amd64
libc6-dev-amd64


Yes... here's lin64.tar.gz if you didn't catch my little scripts before.
BTW: if there's a better way, please let me know. ...After I got this to work I kinda quit looking ;-)
