Export Processing Sketch for Mac on Windows

DavidB

I have just completed a Processing sketch that I would like to share online for users of Windows, Linux, and Mac. The Windows and Linux builds were a piece of cake, but the Mac export does not work on Windows because of the nature of the operating system. Even though I cannot export my sketch for Mac using the traditional methods that Processing offers, could I perhaps do it some other way? I have the libraries that are specific to Mac accessible to me. Now all I need to do is combine them in such a way that the sketch will run. Does anyone have any suggestions for how to go about doing something like this?

I assume that you are using a contributed library - if so which one(s)?

If you are using OS specific binaries then the following code will detect which OS the sketch is running on

String platformName;

final byte MACOSX = 0;
final byte WINDOWS = 1;
final byte LINUX = 2;
final byte OTHER = 3;
byte os;

void setup() {
  os = getOS();
  printOS(os);
}

byte getOS() {
  String platformName = System.getProperty("os.name");
  platformName = platformName.toLowerCase();
  if (platformName.indexOf("mac") != -1) {
    return MACOSX;
  } else if (platformName.indexOf("windows") != -1) {
    return WINDOWS;
  } else if (platformName.indexOf("linux") != -1) { // true for the ibm vm
    return LINUX;
  } else {
    return OTHER;
  }
}

void printOS(byte os) {
  switch(os) {
  case MACOSX:
    println("Mac OSX");
    break;
  case WINDOWS:
    println("MS Windows");
    break;
  case LINUX:
    println("Linux");
    break;
  default:
    println("Unrecognised OS");
  }
}  

then you could use

System.loadLibrary("library name");

to load the correct library.

BTW their maybe a Processing method to report the OS but I couldn't find it.

println( javaVersionName );
println( System.getProperty("java.home")  + "\n" );

println( System.getProperty("os.arch") );
println( System.getProperty("os.name") );
println( System.getProperty("os.version") + "\n" );

println( System.getProperty("user.home") );
println( System.getProperty("user.dir")   + "\n" );

println( sketchPath );
println( dataPath("") );

exit();

You could use SvgExe to package up the natives you need. It's available right from the Processing IDE, in the "tools" menu.
