Clojure (load-file) gives an error

Question

Whenever I try to use (load-file) on my home computer (OSX) it throws the following error:

IllegalArgumentException Parameter declaration comp should be a vector clojure.core/assert-valid-fdecl (core.clj:6732)

When I load the same file on my Windows box at work it works. What is the difference between (load-file "C:\clojure\pc-3.clj") and (load-file "/Users/myname/clojure/pc-3.clj") that is throwing the error. Other than the path structure with the slashes is different but I don't understand why this is not working on my both systems.

BTW: Other than OS both systems are running JRE 1.7_025 with clojure-1.5.1.

UPDATE: I was asked for a stack trace and I'm not sure how to do this just started working with Clojure. But emacs nrepl-error buffer listed this out for me:

UPDATE: Found out what the problem was today. I was having the exact same problem with my Windows box turns out that the original answer was correct but my assumption that it had to do with (load-file) was incorrect. The file I was loading had a function that was not using a vector [] as part of the function itself. Clojure was doing the correct thing (but I totally forgot about this) when loading the file checking the syntax to make sure that everything was complete in the file. My function wasn't so it wouldn't load the file. I forget that LISPs do this and that it's a feature not a bug (reason why I like LISPs).

I'm new to clojure but not to LISPs and I should have realized this. The file is my study file. All the examples I retype from the REPL why studying and the reload the file with the newest to make sure I typed it in correct. It appears that when I added the newest function to file I retyped it incorrect and didn't reload the file to check it. When I went away and closed down the REPL and then came back after dinner and tried to reload the file it wouldn't load.

So sorry for being a waste of time. But thanks for the help, and quickly too. The original answer was correct I just forgot to recheck all the functions in the file.

Answer 1

That error indicates that the compiler was processing something like

(defn function-name comp (do-stuff ...))

or perhaps

(defn [arg1] comp (do-stuff ...))

instead of

(defn function-name [comp] (do-stuff ...))

load-file takes a string not a vector (load-file "path/to/file.clj) Could it be that the code is not the same on the two systems?
Could there be a difference in path interpretation / vs \ causing something else to get loaded?
