再问debian内核源码的问题！郁闷死了。
我在各位的指导下，下了kernel-source-2.4.27,kernel-headers-2.4.27-2-386结果在/usr/src下有了kernel-source-2.4.27，kernel-headers-2.4.27-2,kernel-headers-2.4.27-2-386几个文件夹，为什么会有两个kernel-headers呢？后来我写了个简单的模块程序：
#include <linux/module.h>
int init_module(void)
{
printk("Hello,world!\n");
return 0;
}
void cleanup_module(void)
{
printk("Bye!\n");
}
它的makefile如下：
CC=g++
INCLUDE=-I/usr/src/kernel-source-2.4.27/include/
CFLAG=-D__KERNEL__ -DMODULE -Wall -O2 -g
hello.o:hello.c
$(CC) $(INCLUDE) $(CFLAG) -c hello.c
结果出了很多错：
g++ -I/usr/src/kernel-source-2.4.27/include/ -D__KERNEL__ -DMODULE -Wall -O2 -g -c hello.c

make: *** 错误 1
于是我把
INCLUDE=-I/usr/src/kernel-source-2.4.27/include/
改成：-I/usr/src/kernel-headers-2.4.27-2-386/include/和
-I/usr/src/kernel-headers-2.4.27-2/include/
都不行，为什么？
又下了 kernel-patch-debian-2.4.27 kernel-tree-2.4.27两个包，结果/usr/src下只有kernel-patch，后面的kernel-tree不知道那去了，debian下的内核源代码究竟是哪个啊？感觉好乱啊，不想redhat那么清晰！
求大虾们指点啊。。。 你原来的内核的版本号是多少, 如果和你下的src版本不一致的话, make modules是会报错的, 我用的debian是2.4.27-2-386啊，我用uname -r查看的哦 ！这个多的headers包，究竟哪个是真正的头文件包啊？
下了kernel-source-2.4.27
可是看你下的是2.4.27嘛 :arrow:
