The way to do this depends on your Linux distribution. You didn't

Thank you. I installed debian-31r1a that was downloaded from
debian.org. The kernelversion is 2.4.

Thanks for directing me to this link, I can not compile the example. Is
it because of the lack of the kernel source tree?

1. Untar the kernel tarball or go to the linux kernel tree if you have
already done that
2. make menuconfig. ( Set your hardware drivers/filesystems)
3. make menuconfig/oldconfig/xconfig
4. make dep (only for linux 2.4 , for 2.6 skip this step)
5. make bzImage
6. make modules
7. make modules_install
8. Install this generated bzImage in grub (bootloader)

Do I need to create and enter /usr/src/linux before untar the kernel
zipped file that was downloaded from kernel.org, e.g.
linux-2.6.16.tar.gz.

I downloaded the newest kernel source, and is it correct for me to
configure a 2.6.x kernel source tree on kernel 2.4 Debian Linux
machine?

There were errors after I did this. I created /usr/src/linux and
unpacked the kernel source package there.

Is configuring the kernel source tree is similar to upgrading the
kernel? About half year ago, I had done a kernel upgrade from 2.4 to
2.6 on another machine. I remember that I also can not run this
command, I just used make config at that time. Following is a full log
of that upgrade on my machine.

$ kernelversion
2.4
$ cd linux-2.6.16/linux-2.6.16/
$ make config
$ make
$ su root 'make moudules_install'
$ su root 'cp linux-2.6.16/linux-2.6.16/arch/i386/boot/bzImage
/boot/vmlinuz-2.6.16-386'
$

$ su root 'mkinitrd -o /boot/initrd.img-2.6.16 2.6.16'

Alter boot entries in Grub record typically /boot/grub/menu.lst, add
following section at the bottom part of the file

#jhl, kernel 2.6
title kernel.org, kernel 2.6.16-386
root (hd0,0)
kernel /boot/vmlinuz-2.6.16-386 root=/dev/sda1 ro
initrd /boot/initrd.img-2.6.16 2.6.16
savedefault
boot

$ su root -c 'shutdown -r 10'
$ kernelversion
2.6
$

No, no need to go in /usr/src/linux/ .... actually when you install
source rpm (SRPM) of kernel in redhat linux it installs the source
there (/usr/src/linux).

yes, you can configure and install 2.6 kernel on 2.4 distribution. Just
have to worry about the modules.

What errors?

Upgrading is configuring, building and installing
unlike configuring is only configuring.

Which architecture do you have?
make config is as good as make menuconfig.

This is installing kernel image.

Thank you for the kind help.

There are many errors for make menuconfig[1], following are some of
them. Perhaps I did not install one library for the text style menu,
and got those error message. I can invoke the $ base-config on Debian
Linux, it's a text style menu application. Last time, when I did the
kernel upgrade from 2.4 to 2.6 on Debian, I also can not execute $ make
menuconfig. I executed $ make config to achieve that upgrade. (But now
I even get errors on $ make config[2]!)

I use the Intel Pentium 4 CPU. Do I answer the question?

It seems your gcc has some problem. Try upgrading it or post this
problem to GCC list.
