由一道笔试题想到的：原码反码和补码

有一个简单的helloworld驱动程序，只有基本的安装和卸载功能，并打印出语句。现在已经在PC上编译出.ko模块，然后insmod加载到内核，这些都已经实现了。现在我想把这个驱动加载到2440开发板的嵌入式linux上，于是arm-linux-gcc交叉编译,但是报错了，请问如何解决？
我的配置：PC机ubuntu9.04，2.6.28,arm-linux-gcc 4.3.3; 开发板2440，linux 2.6.30
Makefile如下：
# Makefile 2.6

obj-m += hello.o

CC=arm-linux-gcc

KDIR:=/lib/modules/$(shell uname -r)/build

#PWD=$(shell pwd)

all:

make -C $(KDIR) M=$(PWD) modules

clean:

make -C $(KDIR) M=$(PWD) clean
报错：
