I'd like to keep my R.P. setup as simple and independent as possible, and avoid hooking it to the Internet. For the purpose, I experimented with the C compiler included in the 0.97 ecosystem. I wrote the Hello World with the nano editor over an USB console connection, which compiled and executed from the command line just fine.
Complications began when trying to access hardware, which requires using the API. So I wrote the blink led C example with the nano editor, replacing the

What am I missing? Such a simple LED blinking app should be compile-able from the command line without all the heavyweight wrestling with github cloning and makefiles, no?
