Greetings!
You are probably here wondering, "How do I extend Node using C++?"
This is a wonderful question. While almost no documentation exists on the subject, combining what little there is with several examples should enable you to accomplish your goal.
Compiling and running node-cc-hello-tutorial:
Make sure Node.js is installed (see "How to Install Node.js")
In a terminal:
git clone git://github.com/jkunkee/node-cc-hello-tutorial.git
cd node-cc-hello-tutorial
node-waf configure build
node say.js 55
I have yet to try this on a fresh system, so node-waf may be lacking some python dependencies.
