Hi everyone,
This is my first shot at kernel programming so please
bear with me.
I am using Rubini's Device Driver book (2nd ed)as a
guide and trying to compile one of the sample device
drivers (scull). However I get tons of errors &
warnings when trying to compile and all of them point
to errors in the kernel sources. I have specified my
KERNELDIR(=/usr/src/linux-2.4.20-8) in the make
command line arguments. Here is a sample of the
output the make command that I get when I do a make
KERNELDIR(=/usr/src/linux-2.4.20-8) .I havent included
all the errors as it is huge.
***************
gcc -D__KERNEL__ -DMODULE
-I/usr/src/linux-2.4.20-8/include -DMODVERSIONS
-include
/usr/src/linux-2.4.20-8/include/linux/modversions.h
-O2 -I.. -c -o main.o main.c

/usr/src/linux-2.4.20-8/include/linux/prefetch.h:13,

from
/usr/src/linux-2.4.20-8/include/linux/module.h:12,
from main.c:25:
/usr/src/linux-2.4.20-8/include/asm/processor.h:60:

parse error before numeric constant
/usr/src/linux-2.4.20-8/include/asm/processor.h:265:
invalid suffix on integer constant
**************
The program exits with an Error 1.
I have compiled and loaded a simple helloworld module
in this same kernel. I am not sure what I am doing
wrong.
Can anyone give me some direction?
Thanks for your help
R S
