Please!!!! Anyone can help me ?!

I have had much problems to compile the Linux Device Driver samples, such as scull.

Some bugs I already fix, but this one is take me a headache!

(Sorry if my english is not very well because I am a brazilian and I speak Portuguese )

The problem is :

[root@nativos scull]# make
cc -D__KERNEL__ -DMODULE -Wall -O2 -I/lib/modules/2.4.18-2cl/build/include -c -o pipe.o pipe.c
pipe.c: In function `scull_p_read':

make: *** [pipe.o] Error 1


Anyone have a idea what is the problem?? If not, tell me about another device driver code I can compile with success. Or tell me a sugestion.
The scull driver have a main.c (I already compiled), a pipe and access.c, some headers and some script to load the module..

My Kernel version is 2.4.18-2cl, and the scull version is 2.1
This samples come from Linux Device Driver Book (Alessandro Rubini) 2nd.

Please, I am very anxious and I need to fix this bugs fastly....

Thank you
