[질문] Linux Kernel Module Programming Guide에 있는 소스 에?

[root@NARAPING modulePrograms]# make
gcc -O2 -DMODULE -D__KERNEL__-W -Wall -Wstrict-prototypes -Wmissing-prototypes-i
system /lib/modules/'uname -r'/build/include -c -o hello-1.o hello-1.c
gcc: cannot specify -o with -c or -S and multiple compilations
make: *** [hello-1.o] 오류 1

문서에 있는 그대로 쳤는데 에러가 나네요. 어떻게 하면 되나요?

#include <linux/module.h>   //모든 모듈에 필요
#include <linux/kernel.h>   //kern_alert에 필요

int init_module(void)

        return 0;
}

void cleanup_module(void)
