一、linux内核

1.查看linux内核版本

uname -r

2.下载对应的linux内核

https://www.kernel.org/pub/linux/kernel/

将内核文件夹解压到/usr/src/

cd /usr/src/linux***(你的内核文件夹)

#make menuconfig

这里会出现错误：

HOSTCC scripts/basic/fixdep

HOSTCC scripts/basic/docproc

HOSTCC scripts/kconfig/conf.o

HOSTCC scripts/kconfig/kxgettext.o

*** Unable to find the ncurses librariesor the

*** required header files.

3.解决问题 继续

#sudo make menuconfig

# 選擇下面的 module

# Networking support ->

# Networking options ->

# Network packet filtering framework (Netfilter) ->

# IP: Netfilter Configuration

4.重新编译系统(比较久)

sudo make all

5.编译模块

sudo make modules_install

这里会出现错误

#make menuconfig

然后进入Loadable module support, 选中Enable loadable module support

可以了 继续编译模块

sudo make modules_install

sudo make install
