openwrt – openwrt

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.

Download

Built firmware images are available for many architectures and come with a
package selection to be used as WiFi home router. To quickly find a factory
image usable to migrate from a vendor stock firmware to OpenWrt, try the
Firmware Selector.

If your device is supported, please follow the Info link to see install
instructions or consult the support resources listed below.

##

An advanced user may require additional or specific package. (Toolchain, SDK, ...) For everything else than simple firmware download, try the wiki download page:

Development

To build your own firmware you need a GNU/Linux, BSD or macOS 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 python3.8+ 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

1. Run ./scripts/feeds install -a to install symlinks for all obtained

packages into package/feeds/

1. Run make menuconfig to select your preferred configuration for the

toolchain, target system & firmware packages.

1. 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).
