Kernel build problem (2.4.18 no SMP)
My Debian 2.4.18 kernel was originally built with SMP enabled. After
seeing reference to sound problems with the SMP kernel, I decided to
rebuild without SMP support. I ran 'make config' and changed only the
SMP option. Then 'make dep' and finally 'make', which fails with a
large number of warnings and an error when trying to compile ksyms.c.
The final error message is that smp_num_cpus is undeclared.
My machine is a P4.
The (rather large) output follows:
make CFLAGS="-D__KERNEL__ -I/usr/src/kernel-source-2.4.18/include -Wall

What do I need to do to make the build work OK?
