adt ANE: Missing implementation for platform: default

Hello,

I'm trying to update an old ANE to support 64-bit (this one: appirater-ane - Appirater ANE - Google Project Hosting, which I've forked here: CaptainN/appirater-ane · GitHub). I've gotten pretty far, but I'm running into an error now that I can't make any sense of.

Here is the command I'm running (from in my git directory, where I've collected all these files):

/Users/kevin/SDKs/AIR17SDK/bin/adt -package -target ane Appirater.ane extension.xml -swc appirater.swc -platform iPhone-ARM libAppirater-ANE.a library.swf

My extensions.xml file looks like this:

<extension xmlns="http://ns.adobe.com/air/extension/3.4">

  <id>com.palDeveloppers.ane.Appirater</id>

  <versionNumber>1</versionNumber>

  <platforms>

    <platform name="iPhone-ARM">

      <applicationDeployment>

          <nativeLibrary>libAppirater-ANE.a</nativeLibrary>

          <initializer>AppiraterExtInitializer</initializer>

          <finalizer>AppiraterExtFinalizer</finalizer>

      </applicationDeployment>

    </platform>

    <platform name="default">

        <applicationDeployment/>

    </platform>

  </platforms>

</extension>

As far as I know, I've got everything else building right (the xcode project, the swc, etc.) but I can't figure out why it's telling me about a "default" platform, when I've specified "iPhone-ARM" everywhere.

Note: The original project has a build.xml file that might be easier to get working - but I don't know what that is or how to use it. Any pointers are appreciated!

Thanks,

Kevin N.
