As Mark
pointed out, last week I sent out a gcjx status
note. I’ve done a lot of gcjx hacking recently, though, and some
of this is now out of date.

In particular, I wrote most of the code for the binary
compatibility ABI, and I made the source-to-tree path robust enough to
compile all of libjava. I also wrote most of the tree-lowering
support for the new 1.5 language features; the only remaining things
are the new metadata (which requires work on libgcj as well), and
switch statements of enum type.

As a simple test, I got this program working when compiled to
native (linked against a prebuilt libgcj, not one made with gcjx yet):

public class q
{
  public static void main(String[] args)
  {
    for (String x : args)
      System.out.println(x);
  }
}

Also, I have patches to get a good part of the build working —
you can build the gcj driver now and get at least
partway into the libjava build.

So, expect another gcjx patch flood soon…

A talk I submitted was accepted to the O’Reilly Open Source
Conference. It is called “The State of Free JVMs”; basically
I’ll talk about where we are, where we’re going, etc, with some cool
demos. Everybody, please show up 🙂

Unfortunately my proposal for JavaOne was rejected. Surely they
rejected it out of fear of GNU Classpath.

I thought I would one-up Anthony’s
Tomcat-on-gcj screen shot with a screen shot of Jonas, compiled
with gcj, running the store demo:

This still has a few performance problems, too, though Andrew is
tracking them down at the moment. And, at the moment getting this
running is a bit of a hack, but that is coming along as well.
