Embedded C library.
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, KVX, 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.
