Question

I have an AIR application that I’m compiling to mobile. There is an iOS native extension (JamPot MobileBackup) that compiles fine when used in the IDE.

However, the IDE isn’t sufficient now that we’re moving to support other platforms and I decided to build an Ant script to run the build process.

The issue is that this particular ANE appears to define the MobileBackup class in the extension code, and not in a separate .as file like the other ANEs that I’m using.

Here’s the error I’m seeing:

[mxmlc] Loading configuration file /Users/anderson/src/flex/4.6.0/frameworks/airmobile-config.xml

[mxmlc]     import ie.jampot.nativeExtensions.MobileBackup;

The mxmlc call looks like this:

<mxmlc 
   file="${app.main.class.file}" 
   output="${build.output.swf.file}" 
   locale="${LOCALE}" 
   static-rsls="false"

   debug="${build.debug.mode}" 
   failonerror="true" 
   fork="true" 
   maxmemory="512m">

  <compiler.library-path dir="${FLEX_HOME}/frameworks" append="true">

  </compiler.library-path>
  <library-path file="${FLEX_HOME}/frameworks/locale/${LOCALE}" append="true"/>
  <library-path dir="${spicelib.lib.path}" includes="*.swc" append="true"/>

  <define name="CONFIG::PRODUCTION" value="${output.config.environment.production}"/>
  <define name="CONFIG::STAGING" value="${output.config.environment.staging}"/>
  <define name="CONFIG::LOCAL" value="${output.config.environment.local}"/>
</mxmlc>

where app.ane.path is the path to the collection of .ane files for the project.

I’ve also tried using library-path instead of external-library-path.

Other than adding a build.xml, I’ve not changed the layout or contents of the Flash Builder project at all, and it still compiles fine within the IDE.

What do I need to do to get this to compile outside of the IDE?

Answer 1

I had this all typed up and decided to make one more attempt before posting. I figured it out so I’ll post the results here for others.

Flash Builder must pull the SWCs out of ANEs for mxmlc’s use. I found a copy of the SWC elsewhere and added it to my libs folder and hey presto, it works.
