In computing, uClibc is a small C standard library intended for embedded Linux systems. uClibc was created to support uClinux, a version of Linux not requiring a memory management unit and thus suited for microcontrollers (uCs; the "u" is a romanization of μ for "micro").[2]
The project lead is Erik Andersen. The other main contributor is Manuel Novoa III. Licensed under the GNU Lesser General Public License, uClibc is free software.

[edit] Features
uClibc is much smaller than the glibc, the C library normally used with Linux distributions. While glibc is intended to fully support all relevant C standards across a wide range of hardware and kernel platforms, uClibc is specifically focused on embedded Linux. Features can be enabled or disabled according to space requirements.
uClibc runs on standard and MMU-less Linux systems. It supports i386, x86-64, ARM (big/little endian), AVR32, Blackfin, h8300, m68k, MIPS (big/little endian), PowerPC, SuperH (big/little endian), SPARC, and v850 processors.
[edit] Buildroot
Buildroot is a set of scripts and patches for easing the generation of a cross-compilation chain as well as the creation of a file system.
[edit] History
Development on uClibc started around 1999.[3] uClibc was mostly written from scratch,[4] but has incorporated code from glibc and other projects.[5]
