Tony Ambardar bf4aa0c6a2 tools/libelf: remove unneeded host library 
This old ELF library dating to 2009 used to be necessary on MacOS but
is not required for building the kernel or tools since [1]. On Linux
systems, libelf is already an OpenWRT build-system prerequisite [2].

Presence of the older library can mask or conflict with the system libelf
and lead to build errors, as seen compiling Linux kernels since v5.8 or
host tools such as dwarves (e.g. pahole).

Remove the unnecessary tools/libelf library and avoid the related issues.

                 on non-linux systems")

OpenWrt logo

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.

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