[ENBD] Compiling enbd under SuSE 8.2

[Simon Oliver]

I want to try enbd on my SuSE 8.2 system (runs 2.4.20 kernel).

I downloaded the stable release of enbd (nbd-2.4.30) but found that it 
wouldn't build the enbd.o kernel module - looking at the package 
contents it looks like only 2.4.19 is supported.

Next I downloaded nbd-2.4.31, patched my kernel source with 
"kernel/patches/enbd-2.4.20.pat", configured the kernel to build enbd as 
a module but now I get the following error when I try to build the module:

gcc -D__KERNEL__ -I/usr/src/linux-2.4.20.SuSE/include -Wall 
-Wstrict-prototypes
-Wno-trigraphs -O2 -fno-strict-aliasing -fno-common -Wno-sign-compare

-march=pentiu

When configuring the kernel build options I notice there are two 
optional components:

ENBD remote ioctl support                                             x 
ENBD remote-read/local-write support

I have tried building with and without these to no avail (should I be 
selecting these extra options or not?).  I can't find any documentation 
on how to patch the kernel and build the module so I could be doing this 
all wrong.

Please help.
