Compile Clojure?

Question

I am new to clojure and I have tried to compile it last night but I couldn't seem to do it and I have no idea. I am on windows and don't know much about java. I just want a stand-alone file that I can give to my friends. (I know they need java) Can anyone help?

Answer 1

How about an all in one Clojure installer for Windows? Unless I misunderstood your question and you want your Clojure files themselves compiled.

If you want to compile your own Clojure files, you can read this explanation on the Clojure site.

Answer 2

for producing a stand alone clojure program Leiningen's uberjar option does just that! Install leiningen and then run:

lein uberjar

and you get a single file that your friends can use to run your program.

Answer 3

The easiest way would be to use Leiningen. You can make a very simple project.clj file for your project with :main pointing to your main file's namespace, and then you could do 'lein uberjar' on the command-line and it would stick all your dependencies in a single executable jar file.

I'll point out that every file that needs to be compiled must have a namespace with :gen-class enabled. For example:

(ns whatever.main
  (:gen-class))

Answer 4

If you are a gradle user, you might be interested in Clojuresque (source at bitbucket). It provides similar to leiningen an ueberjar task, which packages up all necessary dependencies in a single jar. It allows easy compilation as well as simple deployment to Clojars. (Although this does currently not work on Windows.)
