The clang/LLVM/musl based ELLCC embedded cross compilation tool chain (http://ellcc.org) now has a binary snapshot available for Mac OS X Mavericks. The tools allow building embedded Linux and standalone C/C++ programs on OS X targeting ARM, Mips, PowerPC and x86 32 and 64 bit targets, Binary snapshots are also available for Linux systems running on all the supported targets. Snapshots are available at ftp://ellcc.org/pub The first major step to replace GNU ld with the LLVM lld linker has been completed. ELLCC was able to build itself for the x86_64 using lld. There was a minor bug uncovered in lld with weak alias symbols that was promptly fixed by the talented LLVM developers (Thanks Rafael!) -Rich
