构建可编译的Openwrt系统

交叉编译环境的搭建

构建Openwrt系统

• Ubuntu 16.04

安装依赖库

apt-get install g++
apt-get install libncurses5-dev
apt-get install zlib1g-dev
apt-get install bison
apt-get install flex
apt-get install unzip
apt-get install autoconf
apt-get install gawk
apt-get install patch
apt-get install subversion
apt-get install asciidoc
或者
sudo apt-get install gcc g++ binutils patch bzip2 flex bison make autoconf gettext texinfo unzip sharutils subversion libncurses5-dev ncurses-term zlib1g-dev subversion git-core gawk asciidoc  libz-dev

编译Openwrt基础固件

1. 下载Openwrt的源码

http://archive.openwrt.org/releases/17.01.4/targets/x86/64/lede-17.01.4-x86-64-combined-ext4.img.gz

2. 编译Openwrt系统的各个模块

• 不要使用root权限!!!!!!!!

./scripts/feeds update -a
./scripts/feeds install -a

3. 选择配置编译目标

make menuconfig ----> .config
Target System (x86)
Target Profile()

4. 编译固件

make V=s -j8

5. 获得目标

./bin/targets/x86/generic/
获得:
.tar .elf .img .mainfest

6. 利用编译出的基本模块，构建一个openwrt的基础固件
