Re: Compilation and Class Generation newbie questions
Hello If you declared clojure.examples.hello namespace, then you need to have file hello.clj in clojure/examples/ directory. and you need to have c:\clojure_tests in classpath, something like: java -cp clojure.jar:c:\clojure_tests clojure.main Paulo Sérgio Medeiros at "Mon, 15 Feb 2010 03:13:51 -0200" wrote: PSM> Hello everyone, PSM> I think i've not figured out yet how compile and/or namespace works.

So put your file in src/clojure/examples/hello.clj. Create also a directory called classes. Then invoke clojure with java -cp src;classes;clojure.jar clojure.main -r and compile the namespace as you did before. The compiled classes will end up in the classes directory.
