In computing, uClibc is a small C standard library intended for Linux kernel-based operating systems for embedded systems and mobile devices. uClibc was created to support μClinux, 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").[3]

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 and open-source software.

Features[edit]

uClibc is a wrapper around the system calls of the Linux kernel and/or μClinux.

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.

History[edit]

Development on uClibc started around 1999.[4] uClibc was mostly written from scratch,[5] but has incorporated code from glibc and other projects.[6]
