Folks,<br>
<br>
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).<br>
<br>
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.<br>
<br>
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)<br>
<br>
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.<br>

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. <br>
<br>
Does anyone have a successful recent build?<br>

Hi,<br>
<br>
I hope it's the right mailing list for my question...<br>
<br>
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.<br>
<br>
Unfortunately I cannot compile hotspot VM because of the
following error:<br>
<br>

---------------------------------------------------------------------<br>
<br>
The missing source is there but the complation script seems to
be unable to locate it.<br>
Moreover, I found out that the platform-specific code (PPC in
my case) is NOT there! The directory<br>
<br>
/Users/maxim/bsd-port/hotspot/src/cpu<br>
<br>
doesn't contain any PPC-related code but only those for sparc,
x86 and zero. I have no idea what the latter means though...<br>
<br>
My Question: Is PPC arch deprecated meanwhile? If not, what's
the reason to strip it out from the distribution?<br>
<br>
Is there any possibility to obtain the PPC code for that VM?<br>
<br>
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...<br>
<br>
Info on system I use:<br>
<br>
Processor: PowerPC G5 2.1 GHz<br>
System: Mac OS X 10.5.8<br>
<br>
