How to set up a complete flash flex or air development environment on linux

How to set up a complete flash/flex/air development environment on Scientific Linux, using FDT, Flex SDK 4.0.0 + Air

1. Download the Flex SDK and Air SDK:
   
   mkdir ~/sdks
   cd ~/sdks/
   wget http://fpdownload.adobe.com/pub/flex/sdk/builds/flex4/flex_sdk_4.0.0.14159.zip
   wget http://airdownload.adobe.com/air/lin/download/2.6/AdobeAIRSDK.tbz2

   mkdir ~/sdks
   cd ~/sdks/
   wget http://fpdownload.adobe.com/pub/flex/sdk/builds/flex4/flex_sdk_4.0.0.14159.zip
   wget http://airdownload.adobe.com/air/lin/download/2.6/AdobeAIRSDK.tbz2

2. Extract the Flex SDK then merge the contents of the the Air SDK into the unzipped flex sdk::
   
   mkdir flex_sdk_4.0.0_plus_air
   unzip flex_sdk_4.0.0.14159.zip -d flex_sdk_4.0.0_plus_air
   tar -jxvf AdobeAIRSDK.tbz2 -C flex_sdk_4.0.0_plus_air/

   mkdir flex_sdk_4.0.0_plus_air
   unzip flex_sdk_4.0.0.14159.zip -d flex_sdk_4.0.0_plus_air
   tar -jxvf AdobeAIRSDK.tbz2 -C flex_sdk_4.0.0_plus_air/

Test your Air SDK

1. Download FDT from the powerflasher website:
   http://www.fdt.powerflasher.com/developer-tools/fdt/download/
2. Run FDT, right click on your Flash Explorer>New>New Flash Project
3. Select Desktop>AS3 AIR
   
4. Add some test code to Main.as, eg.:
   
   package
   {
   import flash.display.Sprite;
      public class Main extends Sprite
      {
         public function Main()
         {
            graphics.beginFill(0x334455);
            graphics.drawCircle(100, 100, 100);
         }
      }
   }

   package
   {
   import flash.display.Sprite;
      public class Main extends Sprite
      {
         public function Main()
         {
            graphics.beginFill(0x334455);
            graphics.drawCircle(100, 100, 100);
         }
      }
   }

5. Click on the debug icon to compile the air app:
   
6. If it’s the first time you are compiling the app, you might need to set up a Run Configuration:
   In the Run Configurations window Double click on FDT SWF Application:
   
   Your Project, Main Class and Output should be all selected. If not, click on browse and select src/Main.as.
7. You will probably get an error, complaining about the adl:

   .../flex/bin/adl: cannot execute binary file

   
   This is because the adl that comes with the default 4.0.0 SDK is built for Mac and not Linux.

8. To fix it, you’ll need to compile it with the SDK you downloaded earlier.
   Right click on your project, go to Properties>FDT COmpiler>Configure:
   
9. Click Add, navigate to the sdks folder (~/Documents/sdks/flex_sdk_4.0.0_plus_air/)
   
10. Try compiling the app again.
    You should see the compiled air app:
