如何编译自己需要的 OpenWrt 固件

注意：

1. 不要用 root 用户 git 和编译！！！
2. 国内用户编译前最好准备好梯子
3. 默认登陆IP 192.168.1.1, 密码 password

编译命令如下:

1. 首先装好 Ubuntu 64bit，推荐 Ubuntu 18 LTS x64
2. 命令行输入 sudo apt-get update ，然后输入 sudo apt-get -y install build-essential asciidoc binutils bzip2 gawk gettext git libncurses5-dev libz-dev patch python3 python2.7 unzip zlib1g-dev lib32gcc1 libc6-dev-i386 subversion flex uglifyjs git-core gcc-multilib p7zip p7zip-full msmtp libssl-dev texinfo libglib2.0-dev xmlto qemu-utils upx libelf-dev autoconf automake libtool autopoint device-tree-compiler g++-multilib antlr3 gperf wget curl swig rsync
3. 使用 git clone https://github.com/coolsnowwolf/lede 命令下载好源代码，然后 cd lede 进入目录
4. ./scripts/feeds update -a ./scripts/feeds install -a make menuconfig
5. make -j8 download V=s 下载dl库（国内请尽量全局科学上网）
6. 输入 make -j1 V=s （-j1 后面是线程数。第一次编译推荐用单线程）即可开始编译你要的固件了。

本套代码保证肯定可以编译成功。里面包括了 R20 所有源代码，包括 IPK 的。

二次编译：

cd lede
git pull
./scripts/feeds update -a && ./scripts/feeds install -a
make defconfig
make -j8 download
make -j$(($(nproc) + 1)) V=s

如果需要重新配置：

rm -rf ./tmp && rm -rf .config
make menuconfig
make -j$(($(nproc) + 1)) V=s

编译完成后输出路径：/lede/bin/targets

English Version: How to make your Openwrt firmware.

Note:

1. DO NOT USE ROOT USER TO CONFIGURE!!!
2. Login IP is 192.168.1.1 and login password is “password”.

Let’s start!

First, you need a computer with a linux system. It’s better to use Ubuntu 18 LTS 64-bit.

Next you need gcc, binutils, bzip2, flex, python3.5+, perl, make, find, grep, diff, unzip, gawk, getopt, subversion, libz-dev and libc headers installed.

To install these program, please login root users and type sudo apt-get -y install build-essential asciidoc binutils bzip2 gawk gettext git libncurses5-dev libz-dev patch python3.5 python2.7 unzip zlib1g-dev lib32gcc1 libc6-dev-i386 subversion flex uglifyjs git-core gcc-multilib p7zip p7zip-full msmtp libssl-dev texinfo libglib2.0-dev xmlto qemu-utils upx libelf-dev autoconf automake libtool autopoint device-tree-compiler g++-multilib antlr3 gperf wget swig rsync in terminal

Third, logout of root users. And type this git clone https://github.com/coolsnowwolf/lede in terminal to clone this source.

After these please type cd lede to cd into the source.

Please Run ./scripts/feeds update -a to get all the latest package definitions defined in feeds.conf / feeds.conf.default respectively and ./scripts/feeds install -a to install symlinks of all of them into package/feeds/ .

Please use make menuconfig to choose your preferred configuration for the toolchain and firmware.

Use make menuconfig to configure your image.

Simply running make will build your firmware. It will download all sources, build the cross-compile toolchain, the kernel and all chosen applications.

To build your own firmware you need to have access to a Linux, BSD or MacOSX system (case-sensitive filesystem required). Cygwin will not be supported because of the lack of case sensitiveness in the file system.

GPLv3 is compatible with more licenses than GPLv2: it allows you to make combinations with code that has specific kinds of additional requirements that are not in GPLv3 itself. Section 7 has more information about this, including the list of additional requirements that are permitted.
