Exported application with Syphon server doesn't work in Processing 3.0b3 on Mac OS X 10.10.5?

[tracycollins]

The exported app crashes in the first or second time thru the draw(), I think.

import codeanticode.syphon.*; PGraphics canvas; SyphonServer server;

void settings() { size(640, 240, P2D); }

void setup() { canvas = (PGraphics) createGraphics(640, 240, P2D); server = new SyphonServer(this, "Processing Syphon"); }

void draw() { canvas.beginDraw(); canvas.background(frameCount%255);

surface.setTitle("FRAME " + frameCount

• " | " + nf(int(frameRate), 0) + " FPS" );

  image(canvas, 0, 0); canvas.endDraw(); server.sendImage(canvas); }

I don't know how to debug this to offer more info. It works when I run the app in the Processing IDE.

Any help is greatly appreciated!

Thanks

You need to ensure the Syphon framework is included in your apps Framework folder in the app bundle.

Can you post the crashlog?

[tracycollins]

I'm a newbie, so I'm don't know where to check for the Framework folder. Where should it be?

I looked in syphonTest/application.macosx/syphonTest.app/Contents (syphonTest is the name of Processing app), but didn't find a Framework folder.

Thanks for the help!

[tracycollins]

Also, using the Mac OS Console app, the only message I could find related to Syphon are:

8/21/15 12:41:02.856 PM java[3845]: SYPHON DEBUG: SyphonServerConnectionManager: Start Connection 8/21/15 12:41:02.857 PM java[3845]: SYPHON DEBUG: SyphonServerConnectionManager: Created connection with UUID: info.v002.Syphon.C58B9596-1A87-49DB-B161-7C3639155F88 8/21/15 12:41:04.724 PM java[3845]: SYPHON DEBUG: SyphonServer: Retiring a server at code unload time because it was not properly stopped

[vade]

Oh, well it looks like its properly linking to Syphon if your app is running calls to Syphon Server in the log. If your app crashes, you should get the pop up dialog that says "App X Crashed, send report to Apple", and there is a 'Details" disclosure triangle that unfolds to show the crash log.

Paste that here.

[tracycollins]

Never see the "App X Crashed, send report to Apple" pop-up dialog.

So, I guess my app isn't crashing, but it definitely stops running. Not sure where/why it's hanging, but it's clearly not getting thru more than one pass of the draw() loop.

Also, looks like I was wrong about the SYPHON DEBUG messages above. They are NOT generated when trying to run the exported app, and are generated when running the app in the Processing IDE. So, maybe the Framework isn't included? Where would I find it?

Any other ideas?

Thanks

[vade]

Then go to the folder you mentioned above, add a Frameworks folder, and move the Syphon.framework into there.

[tracycollins]

Tried adding the Syphon.framework to a Framework (as well as a Frameworks) folder. Still the same problem.

[vade]

I don't really use processing, check the v002.info forum and processing.org, I know folks have it working. Maybe 3.0 broke some stuff?

[tracycollins]

OK. Thanks for your help!

[vade]

Sorry I cant be more help with specifics!

@tracycollins @vade @codeanticode

open examples/SendScreen in processing 2.2.1 using Syphon from the IDE and if you build an application - it runs fine

in processing 3.0b4 using Syphon from the IDE - it runs fine if you build the application from 3.0b4 - it FAILS

if you "Show Package Contents" on SendScreen.app and navigate to /Contents/MacOS/SendScreen and run the app from there

here's what outputs in terminal for 2.2.1

Seems like it isn't finding the Syphon library. Did Processing app export change paths locations?

[vade]

Whats the Java path?

Caused by: java.lang.UnsatisfiedLinkError: no JSyphon in java.library.path

[codeanticode]

hey guys, last time I tested the Syphon library with processing 3.0, was an earlier alpha and it worked well. Something in the library loading mechanism might have changed in the betas, need to take a look.

@vade java.library.path is the path (or list of paths) that Java uses to load native libs.

[vade]

@codeanticode ehehe, I meant what is it and is JSyphon in that directory? It would be good to have a FAQ up somewhere on what needs to happen for exported Processing apps to work with Syphon.

Thanks everyone for the input!

[tracycollins]

thanks, all. happy (sad?) to know that it's not something i'm doing wrong.

[codeanticode]

Lots of changes happened in the 3.0 development process, many of which affect contributed libraries. So, this was expected to happen, and will try to fix it asap.

[hype]

@codeanticode Andres... the updates to mesh/lighting smoothness + Syphon/mapping for live stage visuals... can't thank you enough for taking the time to get this sorted.

[knupel]

Just picture of the bug for souvenir ! :)

[veriKami]

@StanLepunK ;-) as I watched my screen... sending... BUT editor screen

[codeanticode]

Fixed in Processing core with https://github.com/processing/processing/commit/881366f59989b994f49e318c971e1132b214735c. 3.0b6 will incorporate the fix, and I will release a new package of the Syphon library to go along with it.

[hype]

@codeanticode awesome... thank you fine sir.

[knupel]

Yeahhhh thx @codeanticode

[tracycollins]

thanks!

For anyone still having a similar problem on newer versions of Mac OS, I recommend this thread which solved my problem: https://github.com/processing/processing/issues/5676#issuecomment-600431170

(Exported applications crash with Syphon because of a problem with P3D and jogl required for Syphon)
