Github has several repos, there's one which works for Guile (and Racket for the 2nd lesson), but you can just use Chicken Scheme 5 for all of them. Here are the commands to build the addons needed for Chicken Scheme 5 and SICP compat. You need gcc, make and similar tools on your Unix machine. Install "build-essential" on Ubuntu, Debian and derivatives will just work. chicken-install -s srfi 203 chicken-install -s srfi 216 chicken-install -s trace Then at ~/.csirc (define (displaynl x) (display x) (newline)) (define pi (* 4 (atan 1.0))) (import scheme) (import (srfi 203)) (import (srfi 216)) Displaynl and "pi" are just for convenience.
