Buildroot
What it is
Buildroot automates the creation of complete Linux systems for embedded devices through cross-compilation. A build can produce a cross-compilation toolchain, root filesystem, Linux kernel image, and bootloader. It supports processors including ARM, MIPS, PowerPC, and RISC-V, with default configurations for hundreds of boards. Build configuration is available through menuconfig, nconfig, xconfig, and gconfig. The project supports several thousand packages, including X.org, Gtk3, Qt 5, GStreamer, Webkit, and Kodi. Buildroot is designed to run on Linux systems; its manual also describes a Vagrant setup for Linux or Mac OS X and provides Windows instructions. The tool is free and open source, and the manual is licensed under GNU General Public License version 2. Releases come every three months, in February, May, August, and November. The 2,025.02 LTS series is listed with support through March 2028, including vulnerability tracking and prioritized fixes. The manual says Buildroot does not generate binary packages such as .deb or .ipkg files.
