ppc405, ppc750, and sh4, all running linux-2.4.17, more or less.
I *can* run Blackdown JRE 1.3.1 on ppc750, but it takes
up rather too much memory, and it doesn't help me on the
other platforms.  Hence my interest in Kaffe.

It's so nice somebody's actually pulling together
goodies from all the open source java efforts into kaffe!

That all sounds sensible.

Thanks, I'll have a go at it.

First thing I noticed is that the libtool included in kaffe
doesn't seem to support the 'make install DESTDIR=...'.
I'm trying libtool cvs now while waiting for the next release
of libtool.   Oddly, it didn't link until I applied this patch:

as per http://sources.redhat.com/autobook/autobook/autobook_167.html#SEC167

I thought that would have been needed even for libtool-1.4.3.
Is that something you should do in your tree, too, perhaps?

I'm still quite uncomfortable with libtool.  This is my third or
fourth run-in with it in a cross-development environment.
I usually end up ripping it out in frustration, but this time
I'm trying out cvs libtool on the off chance it's improved enough
to handle cross-compiling now.

Thanks,
Dan
