Importing gnulib in order to have a local portable library to link against for missing functions currently requires using libtool to produce the libgnu.la library. Ideally, linking would be simple if the rest of the libraries built by elfutils were also built using libtool, as linking them together would not require any manipulations of library paths. However, upstream elfutils does not support building the libraries statically with libtool, so using libtool comes at the cost of creating a huge patch to introduce that functionality. For building on macOS, it turns out that libgnu.la is only needed for building the binaries, and that just one or two objects from libgnu are needed to build the libraries, so in this case, it would be simple to add the specific non-libtool-wrapped library and objects to the link paths as needed, rather than use libtool to link the libtool wrappers, which greatly reduces the need to patch. Not using libtool also makes the original Makefile definitions for LIBADD once again be the right ones to use. However, to be portable, for libdw the wildcard function needs to be used in order to exclude special archive members like "__.SYMDEF" which are not compiled objects because some BSD-like versions of ar include that metadata in the list, or because the library included may have objects from another subdirectory. Also, the rest of the subdirectories have custom "LDLIBS" variables meant for building shared objects only, so define the LIBADD variables with objects from those existing definitions so that when building only the static versions of the libraries, those objects can still be included.

README.md
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 python3.7+ rsync subversion unzip which
Quickstart
-
Run
./scripts/feeds update -ato obtain all the latest package definitions defined in feeds.conf / feeds.conf.default -
Run
./scripts/feeds install -ato install symlinks for all obtained packages into package/feeds/ -
Run
make menuconfigto select your preferred configuration for the toolchain, target system & firmware packages. -
Run
maketo 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.
