2.5.1 - error compiling ksyms.c

2.5.1 - error compiling ksyms.c

[David Relson]

Greetings!

I can't 2.5.1 for a single processor environment.  The compilation of 
kernel/ksyms.c fails as follows:

gcc -D__KERNEL__ -I/usr/src/linux-2.5.1/include -Wall -Wstrict-prototypes 
-Wno-trigraphs -O2 -fomit-frame-pointer -fno-strict-aliasing -fno-common 
-pipe -mpreferred-stack-boundary=2 -march=i686    -DEXPORT_SYMTAB -c ksyms.c
In file included from ksyms.c:24:
/usr/src/linux-2.5.1/include/linux/kernel_stat.h: In function `kstat_irqs':
/usr/src/linux-2.5.1/include/linux/kernel_stat.h:48: `smp_num_cpus' 
undeclared (first use in this function)
/usr/src/linux-2.5.1/include/linux/kernel_stat.h:48: (Each undeclared 
identifier is reported only once
/usr/src/linux-2.5.1/include/linux/kernel_stat.h:48: for each function it 
appears in.)
make[2]: *** [ksyms.o] Error 1

In linux-2.5.1/.config, I have:

	# CONFIG_SMP is not set

This causes linux-2.5.1/include/linux/smp.h to define the symbol using:

	#define smp_num_cpus	1

However in linux-2.5.1/include/linux/modules/i386_ksyms.ver is:

	#define smp_num_cpus	_set_ver(smp_num_cpus)

which seems to undefine the symbol.

What the heck is going on here?

Never mind.  I seem to have corrected the problem by cleaning up and 
rebuilding from scratch, i.e.

         make mrproper
         make xconfig
         make dep
         make bzImage
         make modules
         make install
         make modules_install

and all worked fine.  Now if I can only remember what events lead up to 
encountering trouble, I might have something useful to report.
