Exported applications using either Syphon client or server don't work

[codeanticode]

Tested on Processing 2.1, Mac OSX 10.9, with the default Send/Receive frame examples. The sketches work ok from the PDE, but the exported applications give the following error:

Exception in thread "Animation Thread" java.lang.RuntimeException: java.lang.UnsatisfiedLinkError: no JSyphon in java.library.path at com.jogamp.common.util.awt.AWTEDTExecutor.invoke(AWTEDTExecutor.java:58) at jogamp.opengl.awt.AWTThreadingPlugin.invokeOnOpenGLThread(AWTThreadingPlugin.java:103) at jogamp.opengl.ThreadingImpl.invokeOnOpenGLThread(ThreadingImpl.java:206) at javax.media.opengl.Threading.invokeOnOpenGLThread(Threading.java:172) at javax.media.opengl.Threading.invoke(Threading.java:191) at javax.media.opengl.awt.GLCanvas.display(GLCanvas.java:492) at processing.opengl.PJOGL.requestDraw(PJOGL.java:626) at processing.opengl.PGraphicsOpenGL.requestDraw(PGraphicsOpenGL.java:1598) at processing.core.PApplet.run(PApplet.java:2177) at java.lang.Thread.run(Thread.java:744) Caused by: java.lang.UnsatisfiedLinkError: no JSyphon in java.library.path at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1886) at java.lang.Runtime.loadLibrary0(Runtime.java:849) at java.lang.System.loadLibrary(System.java:1088) at jsyphon.JSyphonServerList.(Unknown Source) at codeanticode.syphon.SyphonClient.listServers(Unknown Source) at ReceiveFrames.setup(ReceiveFrames.java:28)

I don't know how Processing's exporting functionality works, but it needs to copy the required libraries (JSyphon and Syphon.framework) to the appropriate locations inside the exported bundle - hopefully Processing has a mechanism for addons we can use to have it do that..?

[codeanticode]

The exported app contains the files form all the libraries used by the sketch inside /Contents/Java, in the case of a sketch using syphon that folder has:

There needs to be a phase to force install_name_tool to find the framework path, as "Java" is not a location to bootstrap / load normal Mac OS X Frameworks, normally thats the "Frameworks" folder.

Try to move the Syphon.framework into a Frameworks folder inside "contents"

[codeanticode]

ok, thanks for the hint. I just tried moving Syphon.framework into contents/Frameworks, but the error remains the same. "Exception in thread "Animation Thread" java.lang.RuntimeException: java.lang.UnsatisfiedLinkError: no JSyphon in java.library.path"... it is complaining about not finding JSyphon, not the framework, so perhaps the problem is different?

Oh, indeed, you are correct. Apologies. It does appear to be about JSyphon. I do know that that framework loading path may need to be changed based on where libraries are loaded from, if its non standard though. install_name_tool is typically the path to modify that parameter on dylibs, static libs, and frameworks. That said, it does seem like JSYphon isn't even being loaded, which in turn would not attempt to load Syphon.framework. Unsure, about this, as I don't know enough about Processing's add ons loading / configuration.

has it something to do with static and dynamic libraries ?

In case it helps, i have the same error trying to run from intelliJ without making it an exported app. For me this helped as vm option:

-Djava.library.path=/Users/doekewartena/Dropbox/Public/Processing/libraries/Syphon/library

working on 2.2.1, using latest revision. Will post the 1.0 release soon!
