GNU C Library vs EGLIBC

Struggling to choose between GNU C Library and EGLIBC? Both products offer unique advantages, making it a tough decision.

GNU C Library is a Development solution with tags like c, linux, unix, system-apis, core-library.

It boasts features such as Provides interfaces and abstractions for Linux and Unix-like operating systems, Implements core system APIs like open(), read(), write(), malloc(), printf() etc, Includes efficient implementations for common data structures and algorithms, Supports internationalization and localization, Thread-safe and reentrant code for multi-threaded applications, Extensive documentation and manuals for developers and pros including Mature and stable codebase, Widely portable across many platforms, High performance implementations, Rich feature set, Active development and maintenance, Backwards compatibility, LGPL license allows linking into proprietary applications.

On the other hand, EGLIBC is a Development product tagged with c, c-standard-library, math-functions, linux, glibc-alternative.

Its standout features include Implementation of the C standard library, Math functions, Thread-safe locale access, IPv6 support, Wide character support, and it shines with pros like Lightweight and optimized for embedded systems, Compatible API with glibc, Actively maintained and updated, Permissive licensing (LGPL/BSD).

Product Overview

GNU C Library

Description: The GNU C Library (glibc) is a core system library that provides interfaces and abstractions for Linux and other Unix-like operating systems. It implements system APIs like open, read, write, malloc, printf etc. that are called by applications.

EGLIBC

Description: EGLIBC is an open source implementation of the C standard library and math functions. It is used in many Linux distributions as an alternative to the GNU C Library (glibc).
