  10. <p>Buildroot is a set of Makefiles and patches that makes it easy to
  11. generate a complete embedded Linux system. Buildroot can generate any
  12. or all of a cross-compilation toolchain, a root filesystem, a kernel
  13. image and a bootloader image. Buildroot is useful mainly for people
  14. working with small or embedded systems, using various CPU
  15. architectures (x86, ARM, MIPS, PowerPC, etc.) : it automates the
  16. building process of your embedded system and eases the
  17. cross-compilation process.</p>
  18. <p>The major Buildroot features are:</p>
  19. <ul>
  20. <li>Can <b>handle everything</b> in your embedded system development
  21. project: cross-compiling toolchain, root filesystem generation,
  22. kernel image compilation and bootloader compilation. Buildroot is
  23. also sufficiently flexible that it can also be used for only one or
  24. several of these steps.</li>
  25. <li>Is <b>very easy</b> to set up, thanks to its menuconfig, gconfig
  26. and xconfig configuration interfaces, familiar to all embedded Linux
  27. developers. Building a basic embedded Linux system with Buildroot
  28. typically takes 15-30 minutes.</li>
  29. <li>Supports <b>several hundreds of packages</b> for userspace
  30. applications and libraries: X.org stack, Gtk2, Qt, DirectFB, SDL,
  31. GStreamer and a large number of network-related and system-related
  32. utilities and libraries are supported.</li>
  33. <li>Supports <b>multiple filesystem types</b> for the root
  34. filesystem image: JFFS2, UBIFS, tarballs, romfs, cramfs, squashfs
  35. and more.</li>
  36. <li>Can generate an uClibc cross-compilation toolchain, or re-use
  37. your existing glibc, eglibc or uClibc cross-compilation
  38. toolchain</li>
  39. <li>Has a <b>simple structure</b> that makes it easy to understand
  40. and extend. It relies only on the well-known Makefile language.</li>
  41. </ul>
