Overriding variables used in both the macros and the headers like setting REPLACE_FCNTL to 0 while invoking Make causes the function aliases like rpl_fcntl() to not be defined, however the object may still be built with the fnctl() function. Usually this is enough for building while avoiding the need to link the resulting libgnu library to every single other build target for a project in order to include the gnulib copy of the function, because in these cases we don't care which version of the function is used. However for functions like fcntl() this doesn't work as it is designed to use either the alias or standard declaration from gnulib headers in order to be a wrapper for the native host copy of fcntl() by containing recursive calls to fcntl() within itself after undefining the gnulib function declaration. Overriding the variables used by the header when invoking Make causes the header's declarations to be blocked, and this results in the gnulib version of fcntl() to call itself recursively and indefinitely leading to segmentation faults. Fix this by using macros defined with those variables in order to exclude the function during preprocessing. While at it, do the same for reallocarray() so that the configure option --avoid=reallocarray and Make variable REPLACE_REALLOCARRAY set to 0 would have a similar effect. In the future this patch can be expanded to include more functions and some version of this may be upstreamable.

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.
