Open WRT Make Help Doc

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!

Development

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.

Requirements

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.

binutils bzip2 diff find flex gawk gcc-6+ getopt grep install libc-dev libz-dev
make4.1+ perl python3.6+ rsync subversion unzip which

Quickstart

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.

Related Repositories

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.

• OpenWrt Video: Packages specifically
  focused on display servers and clients (Xorg and Wayland).
