1 uClibc-ng - a small C Library for Linux
3 uClibc-ng (aka µClibc-ng/pronounced yew-see-lib-see-next-generation) is a C
4 library for developing embedded Linux systems. It is much smaller than the GNU
5 C Library, but nearly all applications supported by glibc also work perfectly
8 uClibc-ng is a spin-off of uClibc from http://www.uclibc.org
9 from Erik Andersen and others.
11 Porting applications from glibc to uClibc-ng typically involves just
12 recompiling the source code. uClibc-ng even supports shared libraries and
13 threading. It currently runs on standard Linux and MMU-less (also
14 known as µClinux) systems with support for ARC, ARM, Blackfin, i386, M68K/Coldfire
15 MIPS, MIPS64, NDS32, PowerPC, SH, Sparc, X86_64 and XTENSA processors.
17 If you are building an embedded Linux system and you find that
18 glibc is eating up too much space, you should consider using
19 uClibc-ng. If you are building a huge fileserver with 12 Terabytes
20 of storage, then using glibc may make more sense. Unless, for
21 example, that 12 Terabytes will be Network Attached Storage and
22 you plan to burn Linux into the system's firmware...

34 uClibc-ng strives to be standards compliant, which means that most
35 documentation written for SuSv3, or for glibc also applies to
36 uClibc-ng functions. However, many GNU extensions are not supported
37 because they have not been ported, or more importantly, would
38 increase the size of uClibc-ng disproportional to the added
