A Rake + avr-gcc + avrdude scaffold to compile for Arduino without the IDE.

A clever demonstration.

A C compiler for OS X without the overhead of the gigabytes of Xcode.

Includes an interesting description of how it works.

‘Traceur is a JavaScript.next-to-JavaScript-of-today compiler that allows you to use features from the future today.’

‘Buildroot is a set of Makefiles and patches that makes it easy to generate a complete embedded Linux system. Buildroot can generate any or all of a cross-compilation toolchain, a root filesystem, a kernel image and a bootloader image.’

Compiles a subset of Ruby to Common Lisp, and runs it pretty fast.

LLVM to JavaScript Compiler

‘In which I use genetic algorithms to search for optimal LLVM optimizer passes to make Haskell programs faster’ with impressive results.

FAUST is a compiled language for real-time audio signal processing.

Google tool which ‘compiles from JavaScript to better JavaScript. It parses your JavaScript, analyzes it, removes dead code and rewrites and minimizes what's left.’

‘ooc is a modern, object-oriented, functional-ish, high-level, low-level, sexy programming language. it's translated to pure C with a source-to-source compiler. it strives to be powerful, modular, extensible, portable, yet simple and fast.’

Converts JVM, .Net or YARV bytecode to JVM, .Net, JavaScript, Python, C++ or Objective-C.

Compile for Windows/Linux from OS X.
