uClibc-ng - a small C Library for Linux uClibc-ng (aka µClibc-ng/pronounced yew-see-lib-see-next-generation) is a C library for developing embedded Linux systems. It is much smaller than the GNU C Library, but nearly all applications supported by glibc also work perfectly with uClibc-ng. uClibc-ng is a spin-off of uClibc from http://www.uclibc.org from Erik Andersen and others. Porting applications from glibc to uClibc-ng typically involves just recompiling the source code. uClibc-ng even supports shared libraries and threading. It currently runs on standard Linux and MMU-less (also known as µClinux) systems with support for Alpha, ARC, ARM, Blackfin, CRIS, FR-V, HPPA, IA64, LM32, M68K/Coldfire, Metag, Microblaze, MIPS, MIPS64, NDS32, NIOS2, OpenRisc, PowerPC, SuperH, Sparc, x86, x86_64 and Xtensa processors. If you are building an embedded Linux system and you find that glibc is eating up too much space, you should consider using uClibc-ng. If you are building a huge fileserver with 12 Terabytes of storage, then using glibc may make more sense. Unless, for example, that 12 Terabytes will be Network Attached Storage and you plan to burn Linux into the system's firmware... uClibc-ng is maintained by Waldemar Brodkorb and is licensed under the GNU LESSER GENERAL PUBLIC LICENSE. This license allows you to make closed source commercial applications using an unmodified version of uClibc-ng. You do not need to give away all your source code just because you use uClibc-ng and/or run on Linux. You should, however, carefuly review the license and make certain you understand and abide by it strictly. For installation instructions, see the file INSTALL. uClibc-ng strives to be standards compliant, which means that most documentation written for SuSv3, or for glibc also applies to uClibc-ng functions. However, many GNU extensions are not supported because they have not been ported, or more importantly, would increase the size of uClibc-ng disproportional to the added functionality. Additional information can be found at http://www.uclibc-ng.org/. uClibc-ng may be freely modified and distributed under the terms of the GNU Lesser General Public License, which can be found in the file COPYING.LIB. And most of all, be sure to have some fun! :-) -Waldemar
