musl is a C standard library implementation for Linux. This is a wiki maintained by the enthusiastic user community of musl. Some of musl's major advantages over glibc and uclibc are its size, correctness, static linking support and clean code.

Introduction

• Getting started
• FAQ
• Compatibility (software and standards compatibility of the API musl provides)
• Supported Platforms (compilers, architectures, platforms where musl works)
• Projects using musl (linux distributions and other projects using musl)
• Contacts (mailing list, irc, support, discussions)
