I poked around for a bit and found a book that I liked called "Foundation ActionScript 3.0 Animation - Making Things Move!" by Keith Peters ($40).

Page 23 talks about "Using the free command-line compiler" from Adobe.  It (MXMLC) works on Linux (and Windows).

I went to "Adobe Open Source" at http://opensource.adobe.com/wiki/displa … oad+Flex+3
and downloaded the free "Flex 3 SDK" from the "Stable Builds" Build 3.0.1.1092.

I keyed in HelloWorld.as:

package {
     import flash.display.Sprite;
     import flash.text.TextField;

     public class HelloWorld extends Sprite {

         public function HelloWorld() {
             var display_txt:TextField = new TextField();
             display_txt.text = "Hello World!";
             addChild(display_txt);
         }
     }
}

I compiled it using mxmlc from the "Flex 3 SDK" on my Kubuntu 8.04 Linux system and ran it using "Firefox" with Adobe Flash.

It worked as expected.

I then copied the HelloWorld.swf file to a thumb drive and inserted it into my Chumby.

I started SSHD on my Chumby and
$ ssh 192.168.1.136 -l root
on my Kubuntu 8.04 computer.

I then changed to my thumb drive on the Chumby:
chumby:~# cd /mnt/usb
chumby:/mnt/usb# ls
HelloWorld.swf

I then ran the following from Actionscript From ChumbyWiki:

chumby:/mnt/usb# chumbyflashplayer.x -i HelloWorld.swf

What does this mean?  What didn't I do?
