Processing on Raspberry Pi?

in Integration and Hardware • 11 months ago

Is there any plan to get Processing on the Raspberry Pi?

I've tried downloading the linux version, but as it's build for i386 it doesn't work. I have a project that I'd like to port over to the Pi and I'd love to be able to do it with Processing.

Hello,

Is the Java Virtual Machine installe on the Linux for raspberry Pi?

Yes it does have the openJDK JVM 1.6 as supplied from debian linux. The problem is that there's no Processing install available for ARM on Linux.

I tried exporting a project as an application from my Mac and running that on the Pi, but it complains that i386 code cannot be executed on ARM :(

I really do think that the raspberry pi could be a great platform for Processing projects.

Yes, I agree, it would be very cool to be able to run Processing on the Raspberry Pi. I tried to order one, but I have been in the preorder list for weeks now. How did you get yours?

Xerxes Ranby managed to make a build of Processing 2.0a5 for a Tegra2 device, which is ARM, maybe it would run on the Raspberry as well:

http://www.trimslice.com/forum/viewtopic.php?f=48&t=488

You could follow up the discussion on that forum, and ask if he can update the build to 2.0a6.

Thanks very much for that. I'll certainly give it a go and contact Xerxes for more help if it doesn't work.

I'll post back here if I have any news.

I ordered my RPi the day it was released (29th Feb) and only got it last week. Although, they have only been shipping since the beginning of April IIRC. So yeah, be prepared for a long wait.

It works!

I've tried a simple example and it worked although a little slowly, but that's to be expected.

Many thanks for the link.

"I tried exporting a project as an application from my Mac and running that on the Pi"
This method cannot work.
At best, move the jar to the Pi and try to run it with the Java you have on it.
It won't be able to use libraries with native code, like Minim. Not sure if OpenGL is supported there.

I think that's the problem. I have shared libraries in the project which is what java is complaining about.

Doesn't it also run Android ? Have you tried that ?

What? The raspberry pi?

No it doesn't at the moment and it's a point of debate (on the RPi forum) as to whether it's worthwhile making it happen.

When I load processing on to the pi using your instructions above from xerxes, I keep running into snags. I am trying to load processing 2.06a

I think I have the complete processing package extracted and plenty of space( repartitioned the 16GB sd). I run thru the following procedure.

wget http://processing.googlecode.com/files/ ... -linux.tgz
tar zxvf processing-2.0a6-linux.tgz
cd processing-2.0a6/modes/java/libraries/opengl
wget http://jogamp.org/deployment/jogamp-cur ... atforms.7z
7z x jogamp-all-platforms.7z
mv jogamp-all-platforms/jar/*.jar .
cd ../../../..
./processing

When I go to load processsing at the very last step I keep getting a java syntax error with the following path:

/home/pi/processing-2.0a6/java/bin/java: 1: Syntax error: "(" unexpected

any ideas? Done some searching on the processing forums, but not finding much

Thanks!

What is /home/pi/processing-2.0a6/java/bin/java? Is that a shell script to run Java? Perhaps its syntax isn't accepted by the Pi' shell.

Hi

I successfully managed to run Processing on the Raspberry Pi :

- install Java for ARM (OpenJDK through apt-get on Debian)
- download the official zip for Linux 32 bits (version 1.5.1 in my case)
- unzip as usual but then remove the java directory and make instead a symbolic link : java -> /usr/lib/jvm/java-6-openjdk/

Then you should be able to have Processing running.
But as I need to use it without X environment (no display), I had to install the virtual X framebuffer (xvfb)
And if you plan to use Serial communication, you have to replace the rxtx so library by a ARM-compatible one.

If you read french, steps are explained here (look thru Raspberry Pi keyword-related articles) : http://www.pobot.org/Processing-sur-Raspberry-Pi.html

If you need USB serial communications on the RPi with Processing, you have to make changes to the P5 environnment, such as deleting the RXTX .so and replacing with ARM versions, available from " sudo apt-get install librxtx-java"

If you think it's valuable, I may translate my article in english, but the commands in the terminal don't need translation :)

I am currently trying to figure out how to run an OPENGL sketch in processing on the raspberry pi. I installed all probably necessary packages like jogl/gluegen-rt etc, but i can still not manage to make it work on the pi.

currently my error is UnsatisfiedLinkErro: jogamp.common.jvm.JVMUtil.initialize(Ljava/nio/ByteBuffer;)Z - maybe anybody has an idea how to fix this and make it work.

any help would be apreciated and ill keep you updated about my progress.

cheers,

EDIT:

That error above occurs only in the newsest processing version 2.08a, no matter which renderer you select. did anybody manage to get an glsl shader working in processing on the pi?

The UnsatisfiedLinkErro: jogamp.common.jvm.JVMUtil.initialize(Ljava/nio/ByteBuffer;)Z -
is caused by missing gluegen-rt-natives-linux-arm*.jar and jogl-all-natives-linux-arm*.jar inside the processing SVN
http://processing.googlecode.com/svn/trunk/processing/core/library/
They all do exist here:
http://jogamp.org/deployment/jogamp-current/jar/

There was a small jar name change in JogAmp JOGL RC10:
jogl.all.jar is now named jogl-all.jar
make sure Processing include the gluegen-rt.jar and jogl-all.jar in the classpath and that the *natives-linux-arm*jar's is placed next to them.
http://jogamp.org/jogl/doc/deployment/JOGL-DEPLOYMENT.html

The Raspberry Pi OpenGL ES drivers uses a broadcom specific native window instead of a traditional X11 native window. This makes it hard to get the existing processing AWT/X11 code to run hardware accelerated out of the box.
I have recently added Raspberry Pi Broadcom VC IV NEWT driver autodetection to JOGL that will be included in JogAmp JOGL RC11.
https://github.com/sgothel/jogl/commit/20a2a4f27c9d7c029a86a96fa44c7e77d2d7db6b
Autobuilds from Oct-2012 and later will include this auto-detection: http://jogamp.org/deployment/archive/master/?C=M;O=D
This means that P3D will work out of the box on the Pi if you compile/patch processing to use JogAmp NEWT windowing toolkit instead of AWT by default.

I will say the above comment is a bit over my head, but i do understand it will be modifying core directories to point Processings search paths for files.

This leads me to my question;

I have the Processing (2.06) working fine with openJDK, and have compiled applications fine ( side note: to create rasp pi Processing apps, you need to export applet ON the raspberry pi; its what worked for me atleast)

BUT as many are asking, I am trying to grab video capture. i get an error since it is searching for a sun java script, specifically this error:

UnsatisfiedLinkError: jnidispatch (/com/sun/jna/linux-arm/libjnidispatch.so) not found in resource path.

anyone have a workaround for OpenJDK?

You may check this file (library .so) exists on your Pi and copy (or link) it to the applet sketch with the other .so files.

(and side note : you may export the applet on another computer - with more power - but when you move it to the Pi, you have to change some .so with the versions of your Pi)

"...copy (or link) it to the applet sketch with the other .so files"

I'm not sure how to put a path towards the "applet sketch" with other .so files. Could you rephrase/explain ?

For example :

me@raspberry:~ $ cd /path/to/MyP5Applet
me@raspberry:/path/to/MyP5Applet $ cd lib
me@raspberry:/path/to/my/MyP5Applet/lib $ ls
MyP5Applet.jar ... arduino.jar core.jar ....so serial.jar etc.
me@raspberry:/path/to/my/MyP5Applet/lib $ cp /path/to/JNI/libjnidispatch.so .
me@raspberry:/path/to/my/MyP5Applet/lib $ ls
MyP5Applet.jar ... arduino.jar core.jar ....so serial.jar libjnidispatch.so etc.
me@raspberry:/path/to/my/MyP5Applet/lib $ cd ..
me@raspberry:/path/to/my/MyP5Applet $./MyP5Applet
... it works !

I don't have my Pi with me so I can't check for the moment where this libjnidispatch.so is !

And all of these steps leads me to my original problem, that being I have a missing "libjnidispatch.so" file.

suggestion 2?

Could anybody solve this libjnidispatch.so error? I am getting the same one
