我写了一个helloworld的模块,编译的时候却出现了一大堆错误,大家帮忙看一下是什么原

zhangyiheng

#include <linux/init.h>
#include <linux/module.h>
#include <linux/kernel.h>
static int __init gpio_init(void)
{
        int err=0;
            printk("gpio_init\n");
//        err=register_chrdev(IOPORT_MAJOR,"gpio",&gpio_ctl_fops);
        if (err)
        {
                printk("fail to register\n");
                return -1;
        }
       
        printk("success to register\n");
        return 0;
}
int gpio_release(struct inode *inode,struct file *filp)
{
        printk("release this device\n");
        return 0;
}
module_init(gpio_init);
module_exit(gpio_release);
反正我敢担保代码绝对没错,可是用
gcc -Wall -D__KERNEL__ -DMODULE -I/usr/src/linux/include -O2  -c -o hello.o hello.c
编译时却出现了一大堆的错
/usr/src/linux/include/asm/semaphore.h:88: unknown register name `lr' in `asm'
/usr/src/linux/include/asm/semaphore.h:88: unknown register name `ip' in `asm'
/usr/src/linux/include/asm/semaphore.h:88: unknown register name `lr' in `asm'
/usr/src/linux/include/asm/semaphore.h:88: unknown register name `ip' in `asm'
/usr/src/linux/include/asm/semaphore.h:88: unknown register name `lr' in `asm'
/usr/src/linux/include/asm/semaphore.h:88: unknown register name `ip' in `asm'
...
都是这些,高手帮帮忙看一下是什么问题?

代码是有错误的！

在《linux1。0核心游记》
第三部分有模块的编写章节

Makefile:


obj-m := hello.o

KERNELDIR ?= /lib/modules/$(shell uname -r)/build
PWD       := $(shell pwd)

all:
        $(MAKE) -C $(KERNELDIR) M=$(PWD)
