making Embedded Linux easy

http://buildroot.uclibc.org/

概要

  • Buildroot is a set of Makefiles and patches that makes it easy to generate a complete embedded Linux system. Buildroot can generate any or all of a cross-compilation toolchain, a root filesystem, a kernel image and a bootloader image.
  • Buildroot is useful mainly for people working with small or embedded systems, using various CPU architectures (x86, ARM, MIPS, PowerPC, etc.) : it automates the building process of your embedded system and eases the cross-compilation process.

主な機能

  • Can handle everything in your embedded system development project: cross-compiling toolchain, root filesystem generation, kernel image compilation and bootloader compilation. Buildroot is also sufficiently flexible that it can also be used for only one or several of these steps.
  • Is very easy to set up, thanks to its menuconfig, gconfig? and xconfig? configuration interfaces, familiar to all embedded Linux developers. Building a basic embedded Linux system with Buildroot typically takes 15-30 minutes.
  • Supports several hundreds of packages for userspace applications and libraries: X.Org stack, GTK+ 2, Qt, DirectFB, SDL, GStreamer and a large number of network-related and system-related utilities and libraries are supported.
  • Supports multiple filesystem types for the root filesystem image: JFFS2, UBIFS, tarball?s, romfs?, cramfs, Squashfs and more.
  • Can generate an uClibc cross-compilation toolchain, or re-use your existing glibc, EGLIBC or uClibc cross-compilation toolchain
  • Has a simple structure that makes it easy to understand and extend. It relies only on the well-known Makefile language.
