Getting an error when using the opengl renderer

[Ricardo Sanchez]

When I set my sketch to opengl render mode I get the following error:

no jogl in java.library.path

I checked the Leiningen dependencies and I can see org.processing.jogl-1.5.1.jar is there

I'm on a Mac 10.8.3 using Quil 1.5.1 and the CounterClockwise Eclipse plugin

Hi Ricardo,

can you get an opengl sketch working from a plain lein repl (i.e. not through CCW)?

Yes I  can run from the terminal but I get the following message:

Any ideas?

Hi, Ricardo

Can you show your core.clj?

Sure, its a simple sketch that draws a sphere in the center of if:

(ns opengl-test.core

  (:use [quil.core]))

(defn setup []

  (background 0))

(defn draw []

  (background 0)

  (push-matrix)

  (translate (/ (width) 2) (/ (height) 2))

  (sphere 50)

  (pop-matrix))

(defsketch opengl-test

  :title "opengl test"

  :setup setup

  :draw draw

  :size [800 600]

  :renderer :opengl)

(defn -main [& args]

  (opengl-test))

Does anyone using CounterClockWise is having this opengl problem?

[Niels van Klaveren]

Yeah, same problem here with Eclipse CCW 12 and quil 1.6.0.

To fix:
Rightclick project name > Properties
Java Build Path > tab Libraries
Expand Leiningen Dependencies
Click Native Library Location
Click Edit button
Click External Folder
browse to project subfolder \test\target\native\macosx\ choose either x86 or 86_64, depending on 64 or 32 bits Java used.
click OK, OK,OK

Now rightclick on filename of clj file in project explorer and choose Run As > Clojure Application.

Hi Niels,

That works for me, the program compiles but I get the following message in the console
