That's good progress, being able to build itself. I should take a look
at it. It's still going to be interpreter-only (without porting),
right? Would it still be possible to add a compiler port (c1, opto) on
top of it?
Thanks,

Hi Jonathan,
IcedTea (icedtea6 anyhow) has the zero-assembler port which should
build out of the box on any linux/gcc platform. I say should, because
it's new and we're still working out kinks, but it works enought to
build itself on 32- and 64-bit PowerPC, I've had reports of it working
on zSeries and Itanium, and there are a couple of guys working on ARM
as we speak.
Cheers,
Gary

Beyond just getting it to build, to Hotspot uses a fair amount of
machine code internally, which would have to be retargeted to the
SuperH ISA to get it to run. IcedTea helps, but my understanding is
that there would still be probably a few months of work required to
support a new CPU.

Hi Olivier,
OpenJDK does indeed require java to build, but that aside there
is the issue that HotSpot does not support the sh4 processor.
Check out IcedTea instead (http://icedtea.classpath.org/) which
has a) the ability to bootstrap with gcj, and b) support for
building on platforms with no HotSpot support.
Cheers,
Gary

Hello,
I'm currently trying to get java working on a set-top box
(chipset-family : sh4, processor STb1709), running a STLinux OS.
I tried to follow the steps on this tutorial :
http://today.java.net/pub/a/today/2007/11/29/building-the-jdk.html
I won't describe all the difficulties to install all the
dependencies needed to pass the "make sanity"...
The main problem actually is that when I try to make from the
control/make/ directory, I get an error saying that ant can't find
java, and ant seems to be needed for a successful compilation.
It's the same thing with findbugs...
So I'm kind of stuck in a bad loop, ant needs java, java needs ant...
Has anyone tried to get OpenJDK working on a STB?
Advices and help needed!
Thank you,
Olivier
