I have an Opteron 242 system, to which I recently added a second processor and some more memory.  I figured that to take advantage of that processor, all I needed to do was recompile to kernel, reboot, and set "-j3" in the make.conf file.
 
However, there must be something else, since when I try to compile the kernel with smp, I get a whole bunch of errors like this when I run "make":

------------------

So no normal end to the compile.  This is with gentoo-sources 2.6.14-r5.  I can't upgrade that right now for other reasons. The system is compiled as an x86 system, not amd64, and the only change in kernel config is related to smp:
 
dandelion linux # grep -i smp .config
# CONFIG_X86_BIGSMP is not set
CONFIG_SMP=y
CONFIG_X86_FIND_SMP_CONFIG=y
CONFIG_X86_SMP=y

Any ideas?

I'm accustomed to a kernel build ending with information regarding kernel image size.  This build ends with:

There isn't an image in /usr/src/linux/arch/i386/boot/ either.

I don't use genkernel, never have.  I did try the following:

copy the .config to another directory, 
make clean && make mrproper
copy the .config back
make oldconfig
Make

Same end result, though.  The only change in the config from my working single cpu kernel is to answer yes to SMP, as outlined in my original mail.

I wish.  Thanks for the suggestion, though!

Alas, that doesn't make a any difference whatsoever.  So I'm still searching.

Not relevant, but thanks anyway.
