Re: clojure box: Problem with classpath (noob question)
Hello Shawn, thank you for help. Yes, I am using Clojure Box 1.1.0. I changed my .emacs-file to: (setq swank-clojure-classpaths (list c:/Clojure)) I still get the same error. Since I am a total emacs newbie, I might be making a stupid mistake that might not be obvious to advanced users. Anything else I could try?

That is, installing Clojure should create a set of scripts, clj and cljc that start up the repl (or load a script, as in the Wiki) and compile Clojure programs, respectively. The Clojure jars could be in some central location (say, /usr/lib/clojure on a standard *nix system), and these scripts would get all the jars classes from there into the classpath somehow. This way, people new to the system could download, do some make make install or ant install (?) process, and have an immediately working system with little to no effort.

Re: Problem with CLASSPATH
I have the same problem on my Mac as well, i.e. if clojure.jar is loaded from ~/Library/Java/Extensions rather than from the classpath, then clojure does not find files on the classpath. I did some poking around and on my Mac OS X 10.5.6 with Java 6. When I start clojure with clojure.jar only on the CLASSPATH, then the parent CassLoader of the DynamicClassLoader returned by clojure.lang.RT.baseLoader() and/or clojure.lang.RT.getRootClassLoader () is a sun.misc.Launcher$AppClassLoader. That in turn has a parent of class sun.misc.Launcher$ExtClassLoader. When I move clojure.jar to ~/Library/Java/Extensions and restart, then the parent CassLoader of the DynamicClassLoader is a sun.misc.Launcher $ExtClassLoader. Its parent is nil. Since the ExtClassLoader handles loading from extension directories and not from the CLASSPATH as AppClassLoader does, that would explain why the files aren't being found on the CLASSPATH in this case. You can see the differences by using the following in the REPL: With clojure.jar from the CLASSPATH: Clojure user= (. (clojure.lang.RT/baseLoader) getParent) #AppClassLoader sun.misc.launcher$appclassloa...@e47858e user= ^D With clojure.jar from an extensions directory: Clojure user= (. (clojure.lang.RT/baseLoader) getParent) #ExtClassLoader sun.misc.launcher$extclassloa...@cc7ad6 user= ^D Same results if getRootClassLoader is used instead of baseLoader. Don't know if this is Mac-specifc behavior or not. - David On Mar 24, 3:36 pm, Rich rwml...@gmail.com wrote: I think I figured it out.

Re: Problem with CLASSPATH
Has anyone gotten 20090320 to work on a new MacBook Pro running Leopard? With further investigation, it looks like any call to (use...) either explicitly or as part of an (ns...) function call causes clojure to crash since the upgrade. I've fiddled around with the class path, and nothing seems to work. Interestingly enough, my Structure.clj file sets the namespace, but doesn't use any other files. So, I can launch it from the command line like this: java clojure.lang.Script Structure.clj And I don't get any errors. When I open up the REPL, however and try (use 'Structure), It crashes. I would go back to the older version, but I cannot get duck-streams from clojure.contrib to work on that version. Clojure.contrib seems to build without errors, but it just doesn't work. Previously, I'd built both clojure and clojure.contrib from source, and everything worked fine. However, I have no clue which revision that was, so I don't know how to go back to that version. So, I'm stuck between two non-working versions. Which is frustrating, because I'm in the middle of a project, and I need to get things moving again quickly.

Re: Problem with CLASSPATH
The latest version of Clojure incorporated lazy sequences which broke many libraries early on. Most of these problems have been worked out. In my experience you should use the cutting edge version of everything including SLIME. I clone everything from GitHub (clojure, clojure-contrib, swank-clojure, clojure-mode, slime). This has worked for me for the past 6 months with very few problems (except the original transition to lazy sequences).

The following code worked, as long as Structure was in the working directory: Clojure user= (use 'Structure) nil However, after I updated to 20090320, I get the following errors: Clojure user= (use 'Structure) java.io.FileNotFoundException: Could not locate Structure__init.class or Structure.clj on classpath: (NO_SOURCE_FILE:0) In both cases, I'm launching Clojure from the directory that contains Structure.clj as follows: java clojure.lang.Repl What am I doing wrong? Does Structure.clj contain a call to the ns macro? If so, I think you need to move Structure.clj to a subdirectory that matches its namespace. For example, if the namespace is a.b.c then you need a directory in the classpath that contains an a directory that contains a b directory that conains c.clj, not Structure.clj. -- R.

Re: Problem with CLASSPATH
I also had the NO_SOURCE_FILE error when using contrib packages, upon upgrade to 20090320. My CLASSPATH included .. I had to revert to starting clojure with an explicit -cp. I'm new to both Java and Clojure, but this led me to think my CLASSPATH was being ignored. I chalked it up to my misunderstanding or not really keeping track of how I had things set up before, but it seemed different.

Re: Problem with CLASSPATH
. should be set by default. I verified that it was set using (. System getProperties). I also tried explicitly setting the absolute path using -cp. No luck on either count. -Rich- On Mar 23, 5:14 am, revoltingdevelopment christopher.jay.jo...@gmail.com wrote: I also had the NO_SOURCE_FILE error when using contrib packages, upon upgrade to 20090320.

Re: Problem with CLASSPATH
Let me clarify my last post. In both cases, the directory was on the class path (either implicitly as ., or explicitly given the absolute path). However, in both cases I got the same FileNotFound exception. -Rich- On Mar 23, 6:39 am, Rich rwml...@gmail.com wrote: . should be set by default. I verified that it was set using (.
