Very Computer

Running RH 4.2, kernel 2.0.30. Decided to try my hand at tweaking my
kernel a bit. Went through all the HOWTO's etc etc, and ran the
following:

        cd /usr/src/linux
        make xconfig
        make dep
        make clean
        make modules
        make modules_install
        make zImage

but then the next step:

        depmod -a

spewed forth ten or so lines of '***Unresolved Symbols in modules...'

What do I need to do to fix this problem? Best I can figure, it may be
connected to my recompiling the same kernel version as I am currently
running, and thus the modules' .o files end up in the same place in my
/lib/modules/ subdirectories. But that's just a guess, as I obviously
haven't been able to figure out the whole picture.

Any hints?

You need to remove the old modules from /lib/modules.
Then from /usr/src/linux do make modules_install.
That will re-install only the modules that you have complied support
for, thus fixing your problem.

Config you kernel with whatever method you prefer. I use make xconfig.
Do make dep.
Do make clean.
Do make zImage.
When done copy zImage to /vmlinuz, or whever your boot files are.

Remove the old modules from /lib/modules.
Do make modules
Do make modules_install.

I have done this many times when upgrading kernels. I do not get any
error messages.

Keep in mind that some funtions when compiled in the kernel, like
networking, will expect certain modules, even if you don't use them.
Like Appletalk for example.

Hope this helps.

Why use Windows, since there is a door?

Anyway, you only need it if you try to run programs which do need the iBCS
specification. (e.G. pure SCO-programs). There is no rule to use it if you
stick with Linux-programs.
