Java Support on Sparc plattform.

Hello,

recently downloaded and installed Gentoo on my Sparc Sun machine.
Unfortunately i did not find any package containing java for this
architecture. is it possible to install any other java (source) package
instead? is java support planned by gentoo foundation for these types of
machines?

please let me know, java support is very important for me.

Harald.

The foundation has very little to do with development.

Last I heard, the last version of java that worked on sparc was blackdown 1.4.2
(or something like that), but it had a security bug. If java on sparc is really
important to you, then you probably need to run Solaris. Alternatively, you can
convince the blackdown guys (or one of the other JRE/JDK providers) to do
another sparc release.

Re: Java Support on Sparc plattform. [In reply to]

Hello Andrew,

thank“s for your very quick answer.
i don“t know exactly what exactly gentoo foundation and its developers
do. there are a several java sources available for sparc plattform. sun
has binaries for solaris. is it possible to install/transform these
binaries for gentoo? there are a lot of sources available from sun.
would it be possible to install/compile these sources on my machine?
would it be possible for gentoo to generate emerge packages with these
sources?
I knew about blackdown java for sparc, these are unstable and do not
support all official sun java features.

Rumor has it that sun is opening the source to their JRE/JDK, although I
can't confirm nor do I know quite what that actually means. If true,
though, a user on IRC has expressed a strong interest in working on it,
and if all that happens, I am sure we would support the effort.
Unfornately I don't recall off hand who that was. You might /join
#genoo-sparc (on freenode) and ask who the user is and make contact with
him.

There are one or two java source packages in portage which do build and
run. But if "java support is very important for [you]," you would
almost certainly find them to be deficient.

Ferris probably answered your question, but i looked back and found this
sent to this list on sept. 5

Hi All,

As of today, the 2005.1 profiles for sparc32 and sparc64 have been
deprecated. The major change this will cause is that Java is no longer
supported. Basically the SPARC port for the one Java solution that was
available (blackdown) has the following issues:


* Outstanding security issues
* Very unstable performance, particularly on SMP systems
* Version of glibc it needed was holding the toolchain back.


If Java becomes a viable option again, an update will be posted.

Cheers,

Don't know. What you should do is open a bug against sparc requesting
that the sources you are interested be wrapped in an ebuild which would
support a version of java which would be acceptable to you. If you
generate a bug like that, someone --- maybe me --- would at least look
at it.

Don't pursue blackdown; sun's product seems to be superior.

Ferris

Re: Java Support on Sparc plattform. [In reply to]

Hello again,

why should i open a bug? there is no bug in system, it is a missing
feature.
ok, if you mean that this is the only thing that may bring yava to
gentoo linux on sparc. i will do that. must make me familar to gentoo
bug system. hope i will do the request correct.
i know that suns java is much better.

regards, Harald.
