[-- Attachment #1: Type: text/plain, Size: 350 bytes --]

I recently attempted to compile a 2.5.38 kernel with the following results.  
The Makefileis attached.

<SNIP>
arch/i386/kernel/built-in.o: In function `setup_memory':
arch/i386/kernel/built-in.o(.text.init+0xea1): undefined reference to 
`find_smp_config'
make: *** [vmlinux] Error 1

Any ideas?
-- 
Comments and information are appreciated.

Robert

# *DOCUMENTATION*
# Too see a list of typical targets execute "make help"
# More info can be located in ./Documentation/kbuild
# Comments in this file is targeted only to the developer, do not
# expect to learn how to build the kernel reading this file.

# We are using a recursive build, so we need to do a little thinking
# to get the ordering right.
#
# Most importantly: sub-Makefiles should only ever modify files in
# their own directory. If in some directory we have a dependency on
# a file in another dir (which doesn't happen often, but it's of
# unavoidable when linking the built-in.o targets which finally
# turn into vmlinux), we will call a sub make in that other dir, and
# after that we are sure that everything which is in that other dir
# is now up to date.
#
# The only cases where we need to modify files which have global
# effects are thus separated out and done before the recursive
# descending is started. They are now explicitly listed as the
# prepare rule.

# SUBARCH tells the usermode build what the underlying arch is.  That is set
# first, and if a usermode build is happening, the "ARCH=um" on the command
# line overrides the setting of ARCH below.  If a native build is happening,
# then ARCH is assigned, getting whatever value it gets normally, and 
# SUBARCH is subsequently ignored.

# If it is set to "quiet_", only the short version will be printed. 
# If it is set to "silent_", nothing wil be printed at all, since

# Targets which don't need .config
# ===========================================================================
#
# These targets basically have their own Makefile - not quite, but at
# least its own exclusive section in the same Makefile. The reason for
# this is the following:
# To know the configuration, the main Makefile has to include
# .config. That's a obviously a problem when .config doesn't exist
# yet, but that could be kludged around with only including it if it
# exists.
# However, the larger problem is: If you run make *config, make will
# include the old .config, then execute your *config. It will then
# notice that a piece it included (.config) did change and restart from
# scratch. Which will cause execution of *config again. You get the
# picture.
# If we don't explicitly let the Makefile know that .config is changed
# by *config (the old way), it won't reread .config after *config,
# thus working with possibly stale values - we don't that either.
#
# So we divide things: This part here is for making *config targets,
# and other targets which should work when no .config exists yet.
# The main part above takes care of the rest after a .config exists.
