As Marshall indicated, you need to edit your project.clj file - which in turn means you need to have such a file, which you create with: lein new myproject (or whatever you want to call it). Leiningen will create a folder called myproject containing a bunch of stuff including project.clj. If you run `lein repl` inside the myproject folder, it will have access to whatever libraries you've added to project.clj. Example: > lein new math Generating a project called math based on the 'default' template. To see other templates (app, lein plugin, etc), try `lein help new`. > cd math > cat project.clj (defproject math "0.1.0-SNAPSHOT" :description "FIXME: write description" :url "http://example.com/FIXME"; :license {:name "Eclipse Public License" :url "http://www.eclipse.org/legal/epl-v10.html"} :dependencies [[org.clojure/clojure "1.5.1"]]) See :dependencies? That's where you'll add new libraries. You asked about clojure.contrib.math but that is old and no longer maintained, so for contrib libraries, consult this page: http://dev.clojure.org/display/community/Where+Did+Clojure.Contrib+Go (for other non-core/non-contrib libraries, you would search http://clojars.org as Marshall indicated) You'll see: * clojure.contrib.math * Migrated to clojure.math.numeric-tower - lead Mark Engelberg. * Status: latest build status, latest release on Maven, report bugs. And if you go to https://github.com/clojure/math.numeric-tower/ (which is where clojure.math.numeric-tower links to) you'll see: Leiningen dependency information: [org.clojure/math.numeric-tower "0.0.2"] So we'll edit project.clj to include that... and get: > cat project.clj (defproject math "0.1.0-SNAPSHOT" :description "FIXME: write description" :url "http://example.com/FIXME"; :license {:name "Eclipse Public License" :url "http://www.eclipse.org/legal/epl-v10.html"} :dependencies [[org.clojure/clojure "1.5.1"] [org.clojure/math.numeric-tower "0.0.2"]]) Be careful about the brackets! Now we'll start a repl: > lein repl ... user=> (require '[clojure.math.numeric-tower :as math]) nil user=> (math/sqrt 1234) 35.12833614050059 user=> Hope that helps? -- Sean A Corfield -- (904) 302-SEAN An Architect's View -- http://corfield.org/ World Singles, LLC. -- http://worldsingles.com/ "Perfection is the enemy of the good." -- Gustave Flaubert, French realist novelist (1821-1880) -- -- You received this message because you are subscribed to the Google Groups "Clojure" group.
