Permissions Issue when Exporting File (Eclipse - OSX)

NickTaylor

I've transferred a number of projects from a Windows Eclipse workspace to an OSX system. The projects run fine but I'm unable to Export frames/PDFs (Which worked fine on Windows).

Stack Trace snippet: java.io.FileNotFoundException: /aaaaa.png (Permission denied) at java.io.FileOutputStream.open(Native Method) at java.io.FileOutputStream.(FileOutputStream.java:213) at java.io.FileOutputStream.(FileOutputStream.java:162) at processing.core.PApplet.createOutput(PApplet.java:7636) at processing.core.PImage.saveImageIO(PImage.java:3149) at processing.core.PImage.save(PImage.java:3297) at processing.core.PApplet.saveFrame(PApplet.java:4283) at TestC.draw(TestC.java:17) at processing.core.PApplet.handleDraw(PApplet.java:2386) at processing.core.PGraphicsJava2D.requestDraw(PGraphicsJava2D.java:240) at processing.core.PApplet.run(PApplet.java:2256) at java.lang.Thread.run(Thread.java:745) .... (etc)

Skeleton code creating the error: import processing.core.PApplet;

@SuppressWarnings("serial") public class TestC extends PApplet {

public void setup() {
    size(800, 800);
    background(0);
    noLoop();
}

public void draw() {
    fill(255);
    ellipse(width/2, height/2, 200, 200);
    saveFrame("aaaaa.png");
}

}

I've set permissions to 777 for the eclipse & workspace directories and tried running Eclipse as root without success. saveFrame() works fine when building a sketch in Sublime Text 2.

Has anyone come across this before?

Dunno! Perhaps saveFrame() + dataPath("")? :-??
saveFrame(dataPath("aaaaa.png"));

No luck with dataPath :(

Hey nick. Windows and OSX are different for multiple reasons. What might work on windows might not work on OSX.

Try this it could help.

I've replaced the previous core jars (2.2.1) with those from the Processing 3 Pre-release and this has solved the issue.
