I am using 3 HP PC's with Window XP Pro en Processing 2 for development. Last weekend I was trying out Processing 3. To my surprise when running a Processing 3 program the system clock of the computer was speeding up. This happened on all 3 machines! I know java 8 is not completely compatible with XP. But was is it doing with my system clock and why? Any ideas?

Thanks, Henk Siewert

Usage: PApplet <appletname>

For example I am using these 2 Java-files in a project:

Main.java:

`package de.hpi.javaide.firststeps;
import processing.core.PApplet;
public class Main {
    public static void main(String[] args) {
        PApplet.main(new String[]{"--present", "de.hpi.javaide.firststeps.Game"});
    }
}
`

Game.java:

package de.hpi.javaide.firststeps; import processing.core.PApplet; @SuppressWarnings("serial") public class Game extends PApplet { @Override public void setup() { noStroke(); fill(255, 10, 10); rectMode(CORNER); rect(5, -100, 20, 10); } @Override public void draw() { } }

These files come from a course of OpenHPI. Last year processing worked without any problem. Now I get the above shown error code when using any java file using process.

I am using eclipse neon, java version "1.8.0_161" and core.jar (version 3)

Any help appreciated! Thanks in advance for your help!

For an artistic project i need a processing script which automatically convert a SVG or a PDF into a Gcode to then send it to a lasercutter. It seems no library exist for this purpose. I've found this script on Github: https://github.com/Sephen/svgtogcode but it doesn't seem to work with Processing 3.

Thanks for your Help !

So I've just updated to Processing 3 on my 10.10.3 OS X (Yosemite) install, and I'm getting these very cryptic console logs from an unknown source. Hell Google doesn't even know what the smallest parts of the message are. This seems to crash the Capture protocol unless you luckily run the script (without stopping it manually around 3 to 5 times), this is currently making my testing waiting around for it to just magically work. It only works (occasionally, it's not guaranteed) once I get 2 console logs from a strange source called CoreMachDebugLog, which seems to be some sort of kernel level debug message that gets sent to the JVM.

This is the most it prints before crashing if it doesn't work:

Dec 20 07:17:32 computer_name.local CoreMachDebugLog[1040] : CONFIG_CMIO_CLASSNAME CMIO_DP_ModuleTermFunc

Dec 20 07:17:33 computer_name.local CoreMachDebugLog[1042] : CONFIG_CMIO_CLASSNAME CMIO_DP_ModuleInitFunc (null)

Can anybody discern what's going on here?

NOTE: As I was typing this, I left a nonfunctioning version of my script running by accident, and it filled up my computer's RAM! To put this in perspective my computer has 32GB of RAM, what on earth is going on?!?

(Also if I may add the Processing executable I downloaded from the site is still called Processing 2, which seems strange even though the interface has completely changed.)

But when I run it, I have this error :

[opencv fatal error] library not loaded ! THIS VERSION OF OPENCV LIBRARY REQUIRE ADDITIONAL DEPENDENCIES. READ THE INSTALLATION INSTRUCTIONS AT http://ubaa.net/shared/processing/opencv/

Verify that the '\path\to\OpenCV\bin' exists in your system PATH and the java.library.path property is correctly.

error message: C:\Users\XXXXXXX\Documents\Processing\libraries\OpenCV\library\OpenCV.dll: Can't find dependent libraries

A library relies on native code that's not available. Or only works properly when the sketch is run as a 64-bit application.

However, i followed the instruction of ubaa.net I don't know what i can do, I tried everything I could find in forums... I'll go crazy. Please help me :)

Thanks in advance.

processing 3 does work for me in the Processing application, so it's not my code, but rather something about the proclipsing project.

So how do I get processing 3 to work in eclipse? Or NetBeans?

By the way, searching for processing3 in the forum is difficult. Is there a tag for this?

It's my first question, I hope I ask it the right way. I'm confused and worried about the "sketchbook folder. I tried to install processing 3 and missed the opportunity to create a new folder (both versions use the same folder called processing now). Can someone tell me how to structure everything to use both versions (how many folders and where, on a Mac, which names can be used, etc...)? Thank you for your answers, Cheers,

PS: I am using a MBP retina 15' with OS X 10.10.5)

"Since older sketches may not be compatible, we recommend creating a new sketchbook folder, so Processing 2 and 3 can happily coexist. This is a one-time process. Create a new sketchbook folder for use with Processing 3 sketches (recommended!)" I uninstalled Processing 3 and tried to install it another time but the message doesn't appear anymore.

I have decided to try out 3.0a9 following a system format after using 3.0a5 for quite some time.

I'm experiencing an interesting problem where my sketches crashes in the createGUI() function with a NullPointerException after this code

if(frame != null) frame.setTitle("myApp");

and the console prints out the following

Use surface.setTitle() instead of frame.setTitle in Processing 3

I have also tried creating a new sketch, but it has the same problem.

When I installed the G4P library I'm pretty sure it installed v3.5.2, but the printout in the console printer v3.5.3. To be sure I downloaded v3.5.3 from Quarks Place and replaced the installation directory (I saw mention of a NullPointerException fix).
