The docstring for compile <https://clojure.github.io/clojure/clojure.core-api.html#clojure.core/compile> says that "The source for the lib must be in a proper classpath-relative directory", so unfortunately you can't just create the namespace in the REPL and compile it from there. The tutorial on the Clojure site doesn't make that as clear as it could be.
In your revised example, you're setting the classpath incorrectly. The classpath should contain the root of your file tree. For example, if you have the file path "src/clojure/examples/hello.clj", then the classpath should be set to "src". I'm not sure how the "clojure" script you're running works, but you might find Leiningen to be a better starting point. In Clojure 1.9, an official "clj" script is going to be introduced, which might make this process easier. Until then, Leiningen is probably the safer bet.
