musl libc - a new standard library to power a new generation of Linux-based devices. musl is lightweight, fast, simple, free, and strives to be correct in the sense of standards-conformance and safety. musl is an alternative to glibc, eglibc, uClibc, dietlibc, and klibc. For reasons why one might prefer musl, please see the FAQ and libc comparison chart on the project website, http://www.etalabs.net/musl/ For installation instructions, see the INSTALL file. Please refer to the COPYRIGHT file for details on the copyright and license status of code included in musl (standard MIT license). Greetings! With the 0.9.0 release, musl has reached a milestone in completeness and compatibility. All interfaces in ISO C99 and POSIX 2008 base exist in musl, along with a number of non-standardized interfaces based on GNU and BSD libraries and syscall interfaces for Linux-kernel-specific functions. Some interfaces lack obscure or rarely-used functionality needed for strict conformance, but the vast majority of interfaces go above and beyond the requirements for conformance, often promising success where other implementations can fail under resource exhaustion or other corner-case conditions. At this point, hundreds of packages have been successfully built against musl - either out-of-the-box or with minor patches to address portability errors - ranging from low-level system utilities and network daemons to major gui applications. Testing has been conducted using three separate test frameworks and numerous additional standalone test cases to verify the correctness of the implementation. Included with this package is a gcc wrapper script (musl-gcc) which allows you to build musl-linked programs using an existing gcc 3.x or 4.x toolchain on the host. There are also now at several mini distributions (in the form of build scripts) which provide a self-hosting musl-based toolchain and system root. These are much better options than the wrapper script if you wish to use dynamic linking or build packages with many library dependencies. See the musl website for details. The musl project is actively seeking contributors, mostly in the areas of porting, testing, and application compatibility improvement. For bug reports, support requests, or to get involved in development, please visit #musl on Freenode IRC or subscribe to the musl mailing list by sending a blank email to musl-subscribe AT lists DOT openwall DOT com. Thank you for using musl. Cheers, Rich Felker / dalias
