For years, we have struggled and been frustrated at loosing history of files in git, due to the 'copy + add' strategy. This could have been prevented with a double-commit 'mv + add' trick. On the mailing list [0] the discussion was started to put the instructions in a wiki. Instead, it is much better to just script it and put it in the repo. Instead of doing mv + copy, which leads to two commits, but no history on the copied files, it uses move, + copy and merge, which results in three (merge) commits, but keeps the history of all files. As always with renames, `--follow` will be needed. The tool is trivial and works either in the OpenWrt git root directory, or in the actual target directory. Tested on the `realtek` and generic targets. Note, that the tool does not do any of the labor needed after the move, such as updating configs, dropping patches etc. To make sure this script is easily found by any developer, who just wants to do a kernel bump, the script is added here and not to maintainer-tools repo as those scripts are a little bit more specialized. Bumping a kernel is a trivial task that often regular developers do, where most do not even know the existence of maintainer tools, are not part of the main repo they'd clone, not part of the docker container they'd use and so discoverability is probably much more important.

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 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.
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.

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.
