Hello,

First of all, pardon me because I am a total ignorant when it comes down to Java.

I have been wrestling with trying to get the JAVA SWIG bindings of a very popular GIS data abstraction library (GDAL) to play nicely with Processing. If I can get this to work, I will have read/write access to *many* geospatial formats from within processing.

After compiling GDAL I ended up with the following 64bit SWIG JNI bindings files which I dropped in /Documents/Processing/libraries

I used the following sample code

1. import processing.opengl.*;
   import org.gdal.ogr.*;
   import org.gdal.gdal.*;
   
   void setup() {
     size(640, 360, P3D);
     fill(204);
    
     String loadPath = new String("/Library/Python/2.5/site-packages/django/contrib/gis/tests/data/test_poly/test_poly.shp");
     if(loadPath == null)
     {
       println("No file was selected!");
       exit();
       return;
     }
     println(loadPath);
   
     String[] arr = {
       "--debug", "on"
     };
     ogr.GeneralCmdLineProcessor(arr); //exception thrown here
    
   }
   
   void draw() {
     lights();
     background(0);
   }

which gives me the following error:

1. /Library/Python/2.5/site-packages/django/contrib/gis/tests/data/test_poly/test_poly.shp
   Native library load failed.

from inspecting other libraries in the same directory, it seems like the JNI bindings have to be 32-bit. Sadly, if I compile GDAL in 32 bit I loose a key data access driver that I am using - so that is not an option. I went ahead and grabbed the SVN version of Processing and did an 'ant' and 'ant run'. Same error.

Questions:

- Is that the error that I am seeing? If so, how do I create a 64-bit build of Processing in MacOSX?
- Will getting a 64 bit build solve my problems?

Thanks!
