Processing 2.2.1 Serial not working on Export

tdr

Hi,

I experience some problems with this release when exporting the application to windows binaries. Both the 32 and the 64bit versions of the exe are not able to process even Serial.list().

I am running win7 64bit. Both processing versions (x64, x86) show the same problem.

For example, if i call this function

void checkComPort() {
  println("CheckComPort");
  background(0);
  text(Serial.list().length, 50, 50);
}

The exe will hang. When starting directly from processing everything is fine. There is no difference if embed Java is checked or not.

Any ideas? Thanks

I have found the same problem with exports for Windows machines for sketches using the serial library. It's not just Serial.list(). A call to Serial(), for example when initializing a port: myPort = new Serial(this, "COM5", 115200); also hangs when trying to run the exported .exe file. Calls to serial at the beginning of the sketch (in Setup(), or immediately in Draw() ) will cause the program to hang with a ghost window open (has a frame but no filling). If I add delays before the Serial() call, the sketch will run and draw until the call, then it freezes. The export works fine for Mac, and the sketch runs with no problems in processing on the same Windows computer.

Is this a bug? Is there a workaround? Thanks

To follow up, I have tested the problem in Eclipse as well. Serial.list will output all current available ports (I print them in draw here) but establishing a Serial connection produces errors. This is on a Mac, using OSX 10.7.5. I think this may be a related problem, but I am not positive. My Code:

package testserialexport;

import processing.core.PApplet;
import processing.serial.*;

public class TestSerialExport extends PApplet {

    Serial myPort;
    public void setup() {
        size(800,800);
        myPort = new Serial(this, Serial.list()[9], 230400);
    }

    public void draw() {
        for(int i = 0; i < Serial.list().length;i++){
            text(Serial.list()[i],20,20+20*i);
        }
    }

    public static void main(String _args[]) {
        PApplet.main(new String[] { testserialexport.TestSerialExport.class.getName() });
    }
}

The error trace:

Hi, I have exactly the same problem. Codes containing serial port running by processing work fine, but they don't after being exported. What's wrong??

robj66

same here. Not a problem for all users but a showstopper for others. Exported app just hangs on Serial.list()

Workaround is to tell users to install processing/required extra libs and run from source code locally :/

I backed off to "processing-2.1.2-windows64" and the exported serial app works, hopefully there is a bug fix coming.

You need to add the native library to the exported file. Not entirely sure of how to do it, from eclipse is adding the path to the jnilib on the user library.

O.O Searched for 'export' and missed this post. I posted a question here : forum.processing.org/two/discussion/6032/export-application-executable-does-not-run, but obviously this is the problem I'm having. I think I still have 2.1.2 for w32. I'll try that and post back here. PS - Is this forum, err, retardedly slow today? The rest of my interwebz seem fine..

kowalski5233

Yes, OK, that worked exporting it from Processing 2.1.2

Follow Up - exporting from Processing 2.1.2 (available here:[https://www.processing.org/download/?processing]) fixes my problems. The exports using the Serial library work for Windows and Mac without any other fixes required.

I had this problem while running inside eclipse. The problem was related to the java version being run. Although I had Java 1.7, I had not configured Eclipse to use it. Processing uses the default Java so it was getting 1.7 and working fine. To update you installed JVM's in Eclipse, go to the menu item Window->Preferences->Java and add 1.7 as an installed Java version and make it the default. Works now.

Can someone give a link for 2.1.2?
