em8300 - Need help ...

[TheCyberDude]

Trying to do make in /usr/local/modules:

knoppix@CyberSpace:/usr/local/em8300/modules$ make
cat: /lib/modules//lib/modules/2.4.20pre/build/include/linux/autoconf.h: No such file or directory
cat: /lib/modules//lib/modules/2.4.20pre/build/include/linux/version.h: No such file or directory

make: *** [em8300_main.o] Error 1
knoppix@CyberSpace:/usr/local/em8300/modules$

I installed an second Kernel and installed patchs knoppix +
ptrace. Did not patch xfs to this kernel. System runs good.
I thought kernel-headers were produced when compiling an Kernel.

/lib/modules/2.4.20

New at this, do I need to download kernel-headers for
2.4.20, also on internet they have like 2.4.20-3 / -9 / etc.
How do I get the right one?

Also I recompiled the 2.4.20 Kernel with I2C devices built
into the kernel (instead of modules) - I though this was the
problem.

Any HELP greatly appreciated - I want to use my
Hollywood+ DVD-DECODER card to watch DVD's.
(Better Quality then the software decorders)

Thanks ...
