[gentoo-java] System broken due to a use of a 1.5 JDK for a system VM

[gentoo-java] System broken due to a use of a 1.5 JDK for a system VM

[lugduweb]

Hello !

I'm having a problem while trying to emerge Java's Eclipse's SDK with
"xerces" package.
Please see : http://bugs.gentoo.org/show_bug.cgi?id=134232 for log error
and details.

I then saw on http://www.gentoo.org/proj/en/java/tiger-faq.xml that was
maybe due to the use of the 1.5 JDK as a system VM.

So now, I've switched to my 1.4.2.04 JDK but I still have an error
('java-config -S ibm-jdk-bin-1.4.2.04') on the same package.

Not being an expert at all, I don't know what to do :-(



Finally, at the end of the FAQ page I saw this :
"4.  So I went and broke my system by using a 1.5 JDK... how do I fix
it?
We recommend people that have been using a 1.5 JDK for a system VM
switch over to the migration-overlay. The instructions for using it
describe how to make sure everything gets recompiled with a 1.4 JDK. "


Well... the problem now is that I'm not sure to understand how to switch
to this "overlay" ? Do I have to rebuild my all system ?

Could somebody tell me how to check what packages are wrong and what to
do ?
Thanks & best regards.

No, you have to follow
https://projects.gentooexperimental.org/expj/wiki/Using_migration-overlay

The link above has a section "1.5 JDK set as your Generation-1 VM" which
tells you to execute /usr/bin/java-1.5-fixer which gets installed with
the overlay stuff. Previously I think the tiger-faq mentioned direct
link to this fixer script, without need of migrating first. You can try
extracting and running it from
http://dev.gentoo.org/~nichoj/distfiles/java-config-wrapper-0.8.tar.bz2
but not sure if it works :)

Thanks for your answer,

I've downloaded the tools and some extra tools are needed (" You need to
emerge >=javatoolkit-0.1.6") for ex when I do a java-1.5fixer.

So I'm going to try to do this the "clean manner".
I will tell you if it works.
ATM, I'm building a kernel so it will wait a couple of days.

Regards.

Must be some old computer, building a kernel is matter of minutes, not days
here :)

Hi java gurus,

I am stumped... Anyone see this before:


gcc-config error: java wrapper: Unable to determine executable.
        CTARGET=i686-pc-linux-gnu
        exec=java


This is printed for any java-related command, and (AFAIK) comes from
the run-java-tool.

I'm running bleading edge ("migration", "gentoo-java-exterimental"
"gcj-overlay") so I am expecting problems.

But this appears to be related to the fact that "eselect" is the
prefered method for changing package properties, rather than
gcc-config (et. al).

I could simply remove run-java-tool and replace it with a symlink to
the current system jvm, but thats a nasty hack...

thanks for any help,
Mathew
