[原创]linux下netfilter使用的问题

我想使用netfilter进行开发，写了一个非常简单的测试例子，如下：

#include	<stdio.h>
#include 	<linux/netfilter.h>  
#include 	<linux/init.h>  
#include 	<linux/module.h>  
#include 	<linux/netfilter_ipv4.h>  
#include 	<linux/ip.h>  
#include 	<linux/inet.h> 
/** 
 * Hook function to be called. 
 * We modify the packet's src IP. 
 */  
unsigned int my_hookfn(unsigned int hooknum,  
    struct sk_buff *skb,  
    const struct net_device *in,  
    const struct net_device *out,  
    int (*okfn)(struct sk_buff *))  
{  
	struct iphdr *iph;  
	iph = ip_hdr(skb);  
	/* log the original src IP */  
	printk(KERN_INFO"src IP %pI4\n", &iph->saddr);  
	/* modify the packet's src IP */  
	iph->saddr = in_aton("8.8.8.8");  
	return NF_ACCEPT;  
}  
/* A netfilter instance to use */  
static struct nf_hook_ops nfho = {  
	.hook = my_hookfn,  
	.pf = PF_INET,  
	.hooknum = NF_INET_PRE_ROUTING,  
	.priority = NF_IP_PRI_FIRST,  
	.owner = THIS_MODULE,  
};  
static int __init sknf_init(void)  
{  
	if (nf_register_hook(&nfho)) 
	{  
	        printk(KERN_ERR"nf_register_hook() failed\n");  
	        return -1;  
	}  
	return 0;  
}  
static void __exit sknf_exit(void)  
{  
	nf_unregister_hook(&nfho);  
}  
module_init(sknf_init);  
module_exit(sknf_exit);  
MODULE_AUTHOR("test");  
MODULE_LICENSE("GPL"); 
static	int	test(int argc, char*argv[])
{
	printf("--start test--,%d, %s\n",argc, argv[1]);
	printf("--end test--\n");
	return 0;
}

对应的makefile大致如下：

CC		= gcc
LD		= ld
CFLAGS		= -I src/include/ -I /usr/src/linux-headers-4.4.0-57/include -I /usr/src/linux-headers-4.4.0-57/arch/x86/include -I /usr/src/linux-headers-4.4.0-57-generic/include -I /usr/src/linux-headers-4.4.0-57-generic/arch/x86/include/generated -c -fno-builtin -w -fno-stack-protector
LDFLAGS		= -Map proc.map $(LOBJS_UBUNTU)
# This Program
PROC		= dst/test
OBJS		= $(OBJS_TEST)
LOBJS_UBUNTU	= /usr/lib/x86_64-linux-gnu/crt1.o\
			/usr/lib/x86_64-linux-gnu/crti.o\
			/usr/lib/gcc/x86_64-linux-gnu/5.4.0/crtbegin.o\

			/usr/lib/x86_64-linux-gnu/crtn.o\
			-dynamic-linker /lib/x86_64-linux-gnu/ld-linux-x86-64.so.2
OBJS_TEST	=  src/main/test.o
all : realclean everything clean
realclean :
	rm -f  $(OBJS) 
clean :
	rm -f $(OBJS) 
everything : $(PROC) $(OBJS) 
$(PROC) : $(OBJS) $(LIB) 
	$(LD) $(LDFLAGS) -o $(PROC) $^
src/main/test.o: src/main/test.c
	$(CC) $(CFLAGS) -o $@ $<

得到的编译错误提示如下：

我baidu了一下，但网上的资料众说纷纭，有的说“头文件”里少了个分号，有的说将bool改为int就好等等。但我觉得这些似乎不是主要的（因为linux已经很成熟了，这些如果是bug，早就patch了），至于原因是什么，还要请教各位
