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 curl 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

3. git clone -b 19.07 --single-branch https://github.com/Lienol/openwrt openwrt19 命令下载好源代码，然后 cd openwrt19 进入目录

4. ./scripts/feeds clean
   ./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。

7. 编译完成后输出路径：openwrt19/bin/targets

你可以自由使用，但源码编译二次发布请注明我的 GitHub 仓库链接。谢谢合作！

OpenWrt Project is a Linux operating system targeting embedded devices. Instead of trying to create a single, static firmware, OpenWrt provides a fully writable filesystem with package management. This frees you from the application selection and configuration provided by the vendor and allows you to customize the device through the use of packages to suit any application. For developers, OpenWrt is the framework to build an application without having to build a complete firmware around it; for users this means the ability for full customization, to use the device in ways never envisioned.

Sunshine!

To build your own firmware you need a GNU/Linux, BSD or MacOSX system (case sensitive filesystem required). Cygwin is unsupported because of the lack of a case sensitive file system.

You need the following tools to compile OpenWrt, the package names vary between distributions. A complete list with distribution specific packages is found in the Build System Setup documentation.

gcc binutils bzip2 flex python3 perl make find grep diff unzip gawk getopt
subversion libz-dev libc-dev

1. Run ./scripts/feeds update -a to obtain all the latest package definitions defined in feeds.conf / feeds.conf.default

2. Run ./scripts/feeds install -a to install symlinks for all obtained packages into package/feeds/

3. Run make menuconfig to select your preferred configuration for the toolchain, target system & firmware packages.

4. Run make to build your firmware. This will download all sources, build the cross-compile toolchain and then cross-compile the GNU/Linux kernel & all chosen applications for your target system.

The main repository uses multiple sub-repositories to manage packages of different categories. All packages are installed via the OpenWrt package manager called opkg. If you're looking to develop the web interface or port packages to OpenWrt, please find the fitting repository below.

• LuCI Web Interface: Modern and modular interface to control the device via a web browser.

• OpenWrt Packages: Community repository of ported packages.

• OpenWrt Routing: Packages specifically focused on (mesh) routing.

For a list of supported devices see the OpenWrt Hardware Database
