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.

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.
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.
Development on uClibc started around 1999.[3] uClibc was mostly written from scratch,[4] but has incorporated code from glibc and other projects.[5]
