While some +interfaces remain incomplete or yet to be implemented, the ABI is +intended to be stable at this point, and serious efforts have been +made, using three separate test frameworks, to verify the correctness +of the implementation. Many major system-level and user-level programs +are known to work with musl, either out-of-the-box or with minor +patches to address portability errors; the main remaining applications +which definitely will not work are those which require C++ support, +which will be addressed during the 0.8 or 0.9 development series. + +Included with this package is a gcc wrapper script (musl-gcc) which +allows you to build musl-linked programs using an existing gcc 4.x +toolchain on the host. There are also now at least two mini +distributions (in the form of build scripts) which provide a +self-hosting musl-based toolchain and system root: Sabotage Linux and +Bootstrap Linux. These are much better options than the wrapper script +if you wish to use dynamic linking or build packages with many library +dependencies. + +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 trying out musl. +Thank you for using musl.
