[Rtai] Compile error in sample program, why?

[Fabián C. Tommasini]

Hello,
I just start with RTAI and I have some (newbie) problems.
I read "DIAPM RTAI - Beginner's Guide"
(https://www.rtai.org/index.php?module=documents&JAS_DocumentManager_op=downloadFile&JAS_File_id=32)
and I tried to compile the example 1 (scope and rt_process) but there
was a lot of errors in rt_process.c.
I made some changes to makefile (without results):

--------------------- makefile --------------------------
all: scope rt_process.o
	
LINUX_HOME = /usr/src/linux-headers-2.6.23-rtai-3.6.1
RTAI_HOME = /usr/realtime
INCLUDE = -I$(LINUX_HOME)/include -I$(RTAI_HOME)/include
MODFLAGS = -D__KERNEL__ -DMODULE -O2 -Wall

scope: scope.c
	gcc -c -o $@ $<

rt_process.o: rt_process.c
	gcc $(MODFLAGS) $(INCLUDE) -o $@ $<

clean:
	rm -f rt_process.o scope
---------------------------------------------------------

Is it ok?

Make's output:

gcc -D__KERNEL__ -DMODULE -O2 -Wall
-I/usr/src/linux-headers-2.6.23-rtai-3.6.1/include
-I/usr/realtime/include -o rt_process.o rt_process.c

error: ‘CONFIG_X86_L1_CACHE_SHIFT’ no se declaró aquí (no en una
función)

......... an a lot of more!!!

Now, what is the problem?
Clarifications: the CPU is amd64, the Linux kernel is 2.6.23 and RTAI
version is 3.6.1

Thanks for your help!!!!
Best regards,

Fabián
