uClibc-ng - Embedded C library
What is it?
uClibc-ng is a small 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.
Porting applications from glibc to uClibc-ng typically involves just recompiling the source code. uClibc-ng supports shared libraries and threading. It currently runs on standard Linux and MMU-less (also known as uClinux) systems with support for Aarch64, Alpha, ARC, ARM, AVR32, Blackfin, CRIS, C-Sky, C6X, FR-V, H8/300, HPPA, i386, IA64, LM32, M68K/Coldfire, Metag, Microblaze, MIPS, MIPS64, NDS32, NIOS2, OpenRISC, PowerPC, RISCV64, Sparc, Sparc64, SuperH, Tile, X86_64 and XTENSA processors. Alpha, FR-V, HPPA, IA64, LM32, NIOS2, Tile and Sparc64 are experimental and need more testing.

History
uClibc-ng is a spin-off of uClibc (from Erik Andersen) from http://www.uclibc.org. Our main goal is to provide regulary a stable and tested release to make embedded system developers happy.
The first release 1.0.0 with the code name Leffe Blonde was made while visiting Fosdem 2015. It was prepared in a hotel room in Brussels on 1 February 2015. All releases are prepared while drinking a pair of belgian beer since then.
The idea to fork uClibc started in July 2014 and was discussed on the Buildroot and OpenWrt mailinglists.
