I have successfully build RH 8.0's kernel-2.4.18-14. I assume by "custom"
kernel, you mean that the Makefile has an "EXTRAVERSION = -14custom", not
that you've started to make "custom" modules. If you've started making
custom modules, well, YMMV! :)
I installed an re-built the kernel just fine. Why did I want to do this?
Well, two reasons, I like to nuke all the stuff in the kernel I'm NEVER
going to use, and two, I ALWAYS want the APM support to powerdown my LCD
display (on a laptop).
Here's BB's quick steps to building a "stock" RH 8.0 kernel-2.4.18.14.
1. Install the kernel source into /usr/src/linux-2.4.18-14
rpm -ivh kernel-source-2.4.18-14.i386.rpm
2. Since I'm NOT really re-building the exact same kernel, I *always* COPY
the linux-2.4.18-14 directory to another directory, say,
linux-2.4.18-14custom (or whatever you set EXTRAVERSION to. I then work out
of this new directory. This prevents screwups with the link from
/lib/modules/2.4.18-14/build.
3. Ok, let's assume you want to build pretty much what RedHat shipped with.
In my case that's the i686 uni-processor build. So here goes...
cd /usr/src/linux-2.4.18-14custom
# edit Makefile to set EXTRAVERSION to what you really want
make mrproper #<--- ya really should do this!
cp configs/kernel-2.4.18-i686.config .config
make menuconfig
# in menuconfig, just say and say YES to write autoconf.h
make dep
make bzImage
make modules
# be root for the rest of this!
make modules_install
mkinitrd /boot/initrd-2.4.18-14custom.img 2.4.18-14custom
# copy over the kernel files to /boot, as required
# reconfig lilo and/or grub appropriately
I've found that "make mrproper" is almost REQUIRED when dealing with a
RedHat kernel tree. They have left all sorts of .depends and .version and
other junk files around that the kernel build seems to crash and burn unless
you clean it out. Also, mrproper gets rid of the totally useless autoconf.h
file that comes with the package. If you try to build with this autoconf.h
file, it will fail. Because of this, after doing an mrproper, ya gotta run
menuconfig to regenerate a "good" autoconf.h file.
If "make modules_install" worked, you should have a new kernel tree in the
/lib/modules/2.4.18-14custom directory.
Also, you CANNOT BUILD AT ALL with any direct copy of a
configs/kernel-xxx.config file! These RedHat-provided config files are
funny templates. You can copy the one you want over to .config, but you
MUST MUST MUST run menuconfig (or oldconfig or xconfig) on it first,
otherwise autoconf.h will be bogus (or missing). Personally, I don't use
oldconfig or xconfig because I think they are generating an updated .config
file (and autoconf.h file) that are busted. Both oldconfig and xconfig to
not seem to suffix some module-only types with _MODULE correctly (see
CONFIG_SENSORS as an example).
Hope this helps a bit. You should be happy to know that I have built the RH
8.0 kernel, now 3 times, each time customizing it more and more to my
liking. And she's working great.
BB.

Subject: [Fwd: RE: [rhn-users] Problems compiling custom kernel]
I am not sure if this topic is covered under this list or not. The
thread seems dead on the rhn-users list. Possible the wrong list as
well.
In short I am unable to compile modules for a custom kernel using the
2.4.18-14 source that comes with RH 8.0.
I can compile other kernels, and kernel modules, just not the ones for a
custom 2.4.18-14 kernel. I am pretty sure there is a problem some where.
Although I do not know if that problem lies in the kernel-sources for
2.4.18-14 or in my machine? It's a fresh install and I have tried to
uninstall and reinstall the kernel-sources.rpm.
I am looking for a reason or simple a solution. Is there a problem with
the sources, or is it me?
Has anyone out there been able to compile a custom kernel, and kernel
modules using the 2.4.18-14 source from RH?
