Compilation and Class Generation newbie questions
Hello everyone, I think i've not figured out yet how compile and/or namespace works. I'm trying to execute the example posted in http://clojure.org/compilation I've created a file named hello.clj and put the clojure.jar in the same directory (c:\clojure_tests). Then, i started the REPL using the command: java -cp clojure.jar clojure.main And executed (compile 'clojure.examples.hello), but i'm getting the following error: java.io.FileNotFoundException: Could not locate clojure/examples/hello__init.class or clojure/examples/hello.clj on classpath: (NO_SOURCE_FILE:0) If i execute compile with a different namespace like (compile 'hello) then i get the following error: java.io.IOException: The system cannot find the path specified (hello.clj:1) Is there any relationship between the namespace name and the file name? How compile determines which file is going to be compiled? Thanks in advance, Paulo Sergio. -- You received this message because you are subscribed to the Google Groups Clojure group.

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.

How compile determines which file is going to be compiled? From http://clojure.org/compilation: For some namespace my.domain.lib, defined in my/domain/lib.clj, in the classpath, ... 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.
