The compiled library resulting from importing gnulib has been linked to libelf in order to easily cover other link dependencies. However, this is not appropriate for linking libelf to other programs as it bloats the resulting libelf library, and may result in multiple defintions of symbols based on whether or not certain modules from gnulib are included while elfutils already has it's own definition of a function. This is not a problem while building elfutils, because gnulib has it's own way of creating function aliases and special declarations that allow the linker to ignore the original function definitions, however, when libelf is used to link to something else, this results in an error at link time. The gnulib manual recommended linking the libraries directly, but those who have written it may not have considered how this can affect the ability to link that library in other builds, they likely assume the build targets would not be a dependency. Fix this by removing the linking between gnulib and libelf and instead overriding Make variables in order to add linking between gnulib and each of the binaries provided by elfutils, using Make functions to avoid applying it to other subdirectories. The function tdestroy() would still be missing on macOS, but the existence of the gnulib tsearch object having been built is an indicator of whether or not it is needed because it is only built conditionally by gnulib, so include linking that object only when it exists. Block the unnecessary replacement of some functions by gnulib so that future linking with libelf doesn't require the associated gnulib "rpl" prefixed functions. These replacements are very strict in order to correct minor bugs that don't have a real impact in almost all cases or new standards requirements that are not yet in effect or used.

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!
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.
