Folks,
PPC isn't a currently supported architecture for OpenJDK - that is, no
one has contributed any code to support it. I do know of several
proprietary ports, but that doesn't help. :-) I don't even remember the
last time it was potentially supported (I'm pretty sure that PPC never
was supported in the OpenJDK project).
To put in more bluntly, no one has built OpenJDK on PPC here at Oracle
for a *very* long time, and I don't know of any Open port anywhere else.
It certainly would be nice for someone to come forward with a port of
Hotspot to the PPC/Power architecture, as the Freescale stuff (in
particular) is becoming very popular for embedded work. Now that IBM is
part of OpenJDK, maybe they'll be interested? (who knows)
FYI - "Zero" the architecture, is for a zero-assembly version of Hotspot
(that is, a Hotspot version with as little architecture-specific
customizations as possible). If I were porting Hotspot, I'd start with
the Zero codebase, and work from there. But that's just me.

Hello Max,
I have not been able to get it to compile either and at this point no
one has responded to my post about PPC. I am not sure if it will
compile for our platform any more.
Does anyone have a successful recent build?

Hi,
I hope it's the right mailing list for my question...
I'm trying to build opendjdk7 (bsd-port) in my PowerPC Mac. I
downloaded a right bootstrap VM and got platform-independent code
(corba, jaxp, jaxws etc) successfully compiled.
Unfortunately I cannot compile hotspot VM because of the following

---------------------------------------------------------------------
The missing source is there but the complation script seems to be
unable to locate it.
Moreover, I found out that the platform-specific code (PPC in my
case) is NOT there! The directory
/Users/maxim/bsd-port/hotspot/src/cpu
doesn't contain any PPC-related code but only those for sparc, x86
and zero. I have no idea what the latter means though...
My Question: Is PPC arch deprecated meanwhile? If not, what's the
reason to strip it out from the distribution?
Is there any possibility to obtain the PPC code for that VM?
Any help would be highly appreciated. I'm about to contribute to a
open-source project related on Java 1.6 but I cannot run that
software because Apple discontinued PPC macs, their support and
Java development for PPC. So openjdk is my only way to proceed...
Info on system I use:
Processor: PowerPC G5 2.1 GHz
System: Mac OS X 10.5.8
