Re: building gcj on OS X (also AWT)

[John Gabriele <john3g at bestweb dot net>]

Andreas you son-of-a-gun! :D That screenshot is awesome!
It's very exciting to see Java & GCJ & AWT/GTK+ working,
even though it takes a bit of work right now to do it.
You made my night.

When that combination works out-of-the-box, I believe
GCJ is going to then see a giant upsurge of interest.
Very very exciting. I can't wait (well, I actually will
have to since, at the moment, I have neither the time
nor the "mad skillz" to make it happen :).

I've written up some notes that I was planning on
submitting to osnews.com as some sort of an article,
but now that I know how much work it takes to get the
GUI stuff working (and without the GUI stuff, the article
is much shorter), I think I'll hold off for a little while
... also, I've got a job interview coming up next week
that I need to prepare for (instead of fiddling with GTK+
on OS X! :). The article is here:
http://www.bestweb.net/~john3g/gcj_on_osx.html
I'd, of course, be grateful for any corrections/additions/
links anyone has to offer. :)

Ahh. Sweet. I added those to my notes.

Those would be *great*. Also nice would be a binary for Panther
10.3.3. :D

Definitely. Tomorrow morning. :)

That's ok that's ok. :) gtk+ is a fine toolkit to target. As
long as -- eventually, and pretty soon -- there's one that AWT can
wrap (not sure if that's the correct term) and that installs easily
so amateurs like me can quickly and easily get up and running
creating natively compiled Java GUI apps.

Thanks for the screenshot! :)
