Trying to build User-Mode-Linux Kernel

[Harry Courtice]

Hi
I am trying to build a UML kernel from Ubuntu 6.o6.

I've never built a kernel before, so probably doing something basic wrong..

I have 

gcc version:
	 4.0.3 (Ubuntu 4.0.4-1ubuntu5)
Kernel sources: 
	(head -1 Debian.src.changelog)
	linux-source-2.6.15 (2.6.15.27.48) dapper-security

I am following the instructions in "Installing User Mode Linux"
http://cosi.clarkson.edu/docs/kernel/setup/uml/uml.html


I untarred source files to my home directory

root at desktop:~/tar -xvjf /usr/src/linux-source-2.6.15.tar.bz2

Configure went without a problem. I selected the suggested options in the
instructions.

root at desktop:~/linux-source-2.6.15# make ARCH=um menuconfig

Then try to make the kernel.

root at desktop:~/linux-source-2.6.15# make ARCH-um linux

Very quickly get an error:

In file included from include/asm/bitops.h:4
                 ...
                 From arch/um/sys-i386/kernel-offsets.c:3
Include/asm/arch/bitops.h:10:29: error asm/alternative.h: no such file or
directory

Followed by lots of errors "In function 'xxx_bit'" syntax error before
LOCK_PREFIX"


Clearly I'm doing something basic wrong.

Any hints??


Thanks,


Harry.
