[gentoo-java] Questions about packages

[gentoo-java] Questions about packages

[David Highley]

I have some generic questions about the gentoo Java packages. First I
wonder why you would package Sun's Java for x86 and x86_64 platforms
since it can be down loaded from Sun.

Second question is why I do not see any apparent attempts at creating a
package for Sun's distribution on the Power PC platform. I'm interested
in this as we have a need for Java on an embedded OS platform that is
running on a Power PC board. We are very interested in the effort it
would take to build Sun's Java 1.5.x source to create a JRE for this
platform the OS is very Linux like. Thanks

your particular misunderstanding.  Here goes...

Gentoo does not generally build *new* source distributions for the
software packages of others, but repackages existing distributions to
build properly/cleanly on the Gentoo platform.  In other words, since
Sun's JRE and JDK packages are released as binaries, Gentoo packages
them as binaries.  If/when Sun releases the sources for their runtime
under a different licensing model I'm sure you will see such a source
distribution (current Sun licensing and distribution policies don't
easily allow for this).

As to why there isn't a Gentoo package for this binary, the reasons
probably are as follows:

      * I don't know that anyone has ever expressed interest in it (I
        haven't checked).

      * The Java platform on Gentoo has been in a state of flux for
        approximately 1 year now due to the upgrade effort to Java 5 and
        higher.  During much of this time a package-freeze has been in
        effect.

Hope that helps...

Kind of an odd question... We actually package the JDKs / JREs that you
download from Sun, so that  the installation is managed by portage. As
in, you can install, update, remove, etc. Additionally, you can have
multiple versions and vendors installed at the same time, and we have
tools for selecting which one you want to use at a given moment.

I believe that we used to do from-source packages of Sun's distribution.
I don't know the exact story abut why we dropped it, but I think it was
related to licensing issues or build  issues. Could someone that knows
that story (Karl perhaps?) fill in the details ?

But what you're asking about here... I think it's more something you'd
have to talk to Sun about.

I'm not sure if you're aware, but IBM does have a JDK available on the
PPC. Would that suffice?

Just FYI:  Sun *does* have a binary release for an embedded PPC runtime.
I left the details out because I interpreted David's remarks as "why
aren't we providing a package for it in Portage" question.

In case you're interested in the details you can find them here:

Thanks for clearing that Greg.

So... for a real reason now :) There aren't any members of the Java team
with access to PPC hardware.

Thanks for all the responses. We had not worked with the gentoo
distribution so we were just trying to understand what the packaging was
doing. Hopefully we can get our architecture guys to change directions
to a more main line approach.

I did finally locate the IBM down load area. For a company that make
such a big deal about their web products they have horrible web site
structure.

Thanks again for the information.

The Sun PPC port is a royalty version, blackdown who have an older 
sub-licensed ppc port asked if they could have access to the ppc hotspot 
code but nothing so far has happened. Also Apple have a PPC hotspot jvm 
port, again the code for that is under lock and key. Once you have the 
jvm running you are home and dry. Last time I looked IBMs ppc jvm you 
have to be registered to get it but they obviously more invested in ppc 
than anyone else

Some applications are not stable using the ibm jdk on non-POWER ppc systems.

I was not aware of any stability problems with ibm-jdk on any ppc
hardware. If there are problems with any specific apps on Gentoo, please
file bugs over at bugs.gentoo.org so that we can properly look into them.
