這是C文件

#include
#include
MODULE_LICENSE("Dual BSD/GPL");

static int hello_init(void)
{
      printk(KERN_ALERT "hello,world\n");
      return 0;
}

static void hello_exit(void)
{
      printk(KERN_ALERT "Goodbye,cruel world\n");
}

module_init(hello_init);
module_exit(hello_exit);
~

下面是makefile

CC =/usr/local/arm/bin/arm-linux-gcc
KERNELDIR=/home/work/linux2.6
CFLAGS =-D__KERNEL__ -DMODULE -I$(KERNELDIR)/include -O -Wall

hello.hello.c

      $(CC)$(CFLAGS)  -g -c $<

clean:

這時報錯：

到底是什么原因，版主和朋友們能不能幫個忙，謝謝了

回復1樓chengnokia：

#error "Unsupported AT91 processor"

樓主使用的處理器是AT91系列的嗎?最好是找一個支持該處理器或開發(fā)板的Linux整個包,自己移植太累了
