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?

# 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.

# 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.
