GCJ, Ant and packages?

[Martin Egholm Nielsen <martin at egholm-nielsen dot dk>]

Hi there,

I'm trying to create an Ant-script for compiling my .java-files to 
.o-files using gcj. I've been inspired by Adam Megacz' build-script 
(http://gcc.gnu.org/ml/java/2002-11/msg00025.html), but it keeps failing.
In short, I have the single working source-file 
"src/some/pkg/TestClass.java" which I want to compile into the 
destination directory "out".
My build.xml file is given below.

The error is understandable:
=== SNIP ===
    [apply] Assembler messages:
    [apply] FATAL: can't create C:\DATA\1\out\some\pkg\TestClass.o: No 
such file or directory
=== SNIP ===
It's "bound" to fail since the package-directory does not exist. 
However, I don't quite see how in the world Adam's script could ever work?!

Does any of you have a working Ant/GCJ environment - e.g. with a 
homecooked gcj-anttask for compiling native objects.

Best regards,
