Introduction[edit | edit source]
Buildroot is a set of scripts and patches for the creation of a cross-compilation toolchain as well as the creation of a complete root file system. Buildroot provides:
- support for prebuilt or external toolchains
- configuration through menuconfig, gconfig and xconfig interfaces
- lots of available libraries, tools, packages and utilities
- support for all the major filesystems (JFFS2, UBIFS, CRAMFS, ...)
- uClibc, glibc, eglibc generation, or use of the libc from the external toolchain
- easy customization through Makefiles

Getting Buildroot[edit | edit source]
Buildroot releases can be downloaded from http://buildroot.net/downloads/
Daily Snapshots of the latest Buildroot source tree can be downloaded from http://buildroot.uclibc.org/downloads/snapshots/
The source tree can be browsed online: http://git.buildroot.net/buildroot/ and a copy of the repository can be grabbed with the following commands:
- git clone git://git.buildroot.net/buildroot
- git clone http://git.buildroot.net/git/buildroot.git (Use this if you're behind a firewall blocking git)
The following is the project directory tree:
. ├── arch ├── board ├── boot ├── CHANGES ├── Config.in ├── Config.in.legacy ├── configs ├── COPYING ├── docs ├── fs ├── linux ├── Makefile ├── Makefile.legacy ├── package ├── support ├── system └── toolchain
Configuring Buildroot[edit | edit source]
For modifying the Buildroot configuration, enter the project directory and enter the following command:
make menuconfigYou can optionally use the O=<path> parameter to set a (il parametro O= permette di specificare la cartella dove dovranno essere messi i compilati e dove risiede il file dell'attuale configurazione). Si aprirà un menu dal quale è possibile compiere le dovute personalizzazioni (che andranno ad aggiornare l'attuale file .config).Setting up the external toolchain[edit | edit source]
