| 2 | musl libc - a new standard library to power a new generation of |
| 3 | Linux-based devices. musl is lightweight, fast, simple, free, and |
| 4 | strives to be correct in the sense of standards-conformance and |
| 5 | safety. |
| 6 | |
| 7 | musl is an alternative to glibc, eglibc, uClibc, dietlibc, and klibc. |
| 8 | For reasons why one might prefer musl, please see the FAQ and libc |

| Rich Felker | 801b311 | 2011-09-13 13:41:40 -0400 | [diff] [blame] | 20 | Greetings! |
| Rich Felker | 0b44a03 | 2011-02-12 00:22:29 -0500 | [diff] [blame] | 21 | |
| Rich Felker | 8a35dee | 2012-05-05 02:39:51 -0400 | [diff] [blame^] | 22 | With the 0.9.0 release, musl has reached a milestone in completeness |
| 23 | and compatibility. All interfaces in ISO C99 and POSIX 2008 base exist |
| 24 | in musl, along with a number of non-standardized interfaces based on |
| 25 | GNU and BSD libraries and syscall interfaces for Linux-kernel-specific |
| 26 | functions. Some interfaces lack obscure or rarely-used functionality |
| 27 | needed for strict conformance, but the vast majority of interfaces go |
| 28 | above and beyond the requirements for conformance, often promising |
| 29 | success where other implementations can fail under resource exhaustion |
| 30 | or other corner-case conditions. |
| 31 | |
| 32 | At this point, hundreds of packages have been successfully built |
| 33 | against musl, either out-of-the-box or with minor patches to address |
| 34 | portability errors. Testing has been conducted using three separate |
| 35 | test frameworks and numerous additional standalone test cases to |
| 36 | verify the correctness of the implementation. |

| Rich Felker | 801b311 | 2011-09-13 13:41:40 -0400 | [diff] [blame] | 38 | Included with this package is a gcc wrapper script (musl-gcc) which |
| Rich Felker | 8a35dee | 2012-05-05 02:39:51 -0400 | [diff] [blame^] | 39 | allows you to build musl-linked programs using an existing gcc 3.x or |
| 40 | 4.x toolchain on the host. There are also now at several mini |
| Rich Felker | 801b311 | 2011-09-13 13:41:40 -0400 | [diff] [blame] | 41 | distributions (in the form of build scripts) which provide a |
| Rich Felker | 8a35dee | 2012-05-05 02:39:51 -0400 | [diff] [blame^] | 42 | self-hosting musl-based toolchain and system root. These are much |
| 43 | better options than the wrapper script if you wish to use dynamic |
| 44 | linking or build packages with many library dependencies. See the musl |
| 45 | website for details. |
