This morning I did a little GDirect
hacking. It now actually compiles and a short example program works.
I checked it in to the gcjx repository,
since that was convenient for me. It is in the “gdirect” module if
you want to take a look.

I think the next step will probably be developing a way to
represent native pointers in GDirect. Most likely I’ll do this by
boxing and unboxing pointer arguments somehow. Offer suggestions if
you like, my ideas in this area are pretty vague at the moment.
Earlier I was just going to use RawData, but I find I’m
more interested in cross-VM portability than I was before.

Also on the table is the idea of having a notion of classes that
wrap some native object. This would let us wrap non-static methods in
a natural way.
