UClibc

uClibc is a small C standard library intended for embedded Linux systems. It is free software, licensed under the LGPL.

uClibc was created to support uClinux, a version of Linux not requiring a memory management unit and thus suited for microcontrollers (hence the "uC" in the name).

uClibc is much smaller than GNU C Library (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 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, ARM (big/little endian), Blackfin, h8300, m68k, MIPS (big/little endian), PowerPC, SuperH (big/little endian), SPARC, and v850 processors.

The project lead is Erik Andersen. The other main contributor is Manuel Novoa III.
