Re: [xmlvm-users] Examples for iphone-c target

 Arno-

Thanks for the tip, that gives me a starting point.

What is the plan for implementing the native methods that will be needed by the OpenJDK classes? Will they all be hand-implemented, or will you try to use OpenJDK's own C implementations of the native methods? That strikes me as a bigger implementation headache than the number of dependencies you are encountering (I'm sad to say I'm not surprised at the 3K dependencies on Hello World; I don't think you're going to be able to whittle that down by too much without losing some potential functionality).

note that the C backend is undergoing rapid changes. Today we managed to 
get a first version of iFireworks (XMLVM's trademark application) 
working with the C backend. Make sure you update XMLVM and then try this:

ant
java -Xmx700m -jar dist/xmlvm.jar --target=iphone-c \
      --app-name=iFireworks \
      --resource=demo/iphone/ifireworks/ires/ \
      --in=build/demo/iphone/ifireworks/org/xmlvm/demo/ifireworks \
      --out=out
open out/iFireworks.xcodeproj/

There are two big todo items at this point:

1. Implement the Cocoa wrappers. In many cases it should be possible
    to migrate the existing Objective-C wrapper.
2. OpenJDK: the iFireworks demo uses hand-written versions of dependent
    J2SE classes (such as java.lang.String). Our plan is to cross-compile
    OpenJDK. The good news is that the C backend is powerful enough
    to cross-compile OpenJDK. But the bad news is that we are struggling
    with dependencies. A simple Hello World pulls in 3000(!) classes
    from the OpenJDK.

Things are moving fast and I'm sure we'll find solutions to the 
remaining problems. Stay tuned.

Arno
