Half-automated build-script for Java J2SDK from source

does that ebuild actually build it from source though? glancing a the ebuild i would think that it does, but i dont know enough about them to know for sure.

anyone know why the new ebuild depends on blackdown-jdk-1.4.1_beta?

Yes, the new ebuild builds from source, or at least attempts to. I have not gotten it to work yet. Even on a dual Athlon 1800+ system it compiles for over two hours before it craps out, so the frustration level can get pretty high. Personally, I've had enough for a while.

It requires the blackdown sdk (probably the sun-jdk would do) because you have to have the java compiler to build it. I think that is 'javac' in /opt/blackdown-jdk-1.4.1_beta/bin but not sure. I encountered errors very early in my first couple attempts at building saying that javac could not be found, so I added the above dir to my path. That did not work so I put a link to it in /usr/bin and that did the trick. It died much later on an unrelated error that I don't remember offhand.

Fortunately my lappy's Gentoo is still built on 2.95.3 so I can get my NY Times crossword fix there.

Hi there people,
I am the developer who commited and wrote the current java source ebuild in portage. (sun-j2sdk)

The current version in portage, to my knowledge, works fine.

A few points though,

* you have to unmerge openmotif before compiling, you can remerge it latter, it is just to stop java linking to it.

* A java development kit version 1.4 or greater is needed to compile. I have tested it with sun-jdk-1.4.1.01 and blackdown-jdk-1.4.1_beta. Both are fine.
Blackdown is used as default due to the virtual/jdk settings in the profile. Use java-config to change the jdk used after emerging the jdk.

* the ./man/ja error which was seen before was due to libsandbox, that is why I disable sandbox in this ebuild.

* It is very sensitive to CFLAGS!!

Finally a question, anyone had luck compiling java on non-X86 platforms?

See ya,
Stefan (Cretin on IRC)

I still can't get the sun-j2sdk compile successful, even followed the way stated in this thread before.

i get an nearly error like gaplo. enough disk space is availible on my machine

This is because your java-config setting point to a jdk < 1.4. Please adjust your java settings using java-config to use a jdk >= 1.4.
I updated the portage ebuild to check for this at the beginning.

yeah i'm using java 1.3.1 for other tools.

i'm working this out later.

thanks

It was just like christmas when I got up this morning and found a shiny new java-jdk on my desktop :-) Thanks Cretin.

I did an rsync, double checked my java-config settings, and started the build before bedtime. Voila!

I'm getting an error like Gaplo, it's because I don't have a 1.4.1 JDK? I'm using Blackdown 1.3.1 right now, I'll switch to Sun 1.4.1 later I guess... Plenty of disk space.

I realize this is a total newbie question, but could someone explain to me how to switch from using blackdown-jdk-1.3.1 to blackdown-jdk-1.4.1_beta?

Thanks in advance.

to set your jvm try as root:

#java-config --list-available-vms

to get a liat of whats available

and then:

#java-config --set-system-vm=blackdown-jdk-1.4.1_beta

Hi there people, update time:
sun-j2sdk-1.4.0-r2 is now realesed!

I have fixed the problem with sun-j2sdk's java plugin crashing on some websites. This update is highly recommended!

I have yet to make any headway on the compile problems found here, for most people it compiles fine.

to set your java version use
java-config --set-system-vm=blackdown-jdk-1.4.1_beta
or whatever java version you want.
It requires a JDK version 1.4 or greater, sun and blackdown versions work fine for me.

I thank you for your patience, this is my first ebuild from scratch!

Ok, thanks for pointing that out

I knew it would be something that would make me feel dumb for having to have asked. I'm rsyncing to get the new ebuild and then I will try this again. I've tried doing it manually, tried doing it with the script on this thread, and have tried the first ebuild (though with the wrong version java), but hopefully fourth time is the charm.

Cretin - GREAT job, and thank you so much. I haven't compiled Mozilla yet... just finished java. On to emerge mozilla. YEAH.

I only ran into one problem which resulted in the java compile exiting with an error (after over an hour.. argh!).... it couldn't find "zip." Sure enough, when I typed "emerge -p zip" it showed up as not installed. I emerged zip and re-ran your ebuild (r2) and it finished up with no problem. Perhaps this needs to be included as a dependency in your ebuild?

(btw, this is my first post to the gentoo forums - there was no need prior to this, as the "search" engine answered all my questions.

)

EDIT: Finished emerging Mozilla and linking java plugin... works PERFECTLY (so far!) Again, THANK YOU, Cretin!

I used the ebuild, it complete successfully and I moved the plug-in to ~/.mozilla/plugins. Mozilla sees the plug-in but it still says I don't have the needed plug-in when I get to a page that requires java. I used java-config to change to the newly compiled java. If anyone has some advice they think might be helpful it would be greatly appreciated..

Also on a related note, Phoenix doesn't see this plug-in or any of my other plug-ins. Anyone know where I need to put them to get Phoenix to see them?

EDIT - I got this fixed. Turns out it was caused by the fact that I had linked from /usr/lib/mozilla/plugins to ~/.mozilla/plugins because another thread had said that was where phoenix checked for plugins.. but I realized that was obviously the wrong way to go about that. Java works. Yay. Good ebuild btw.

i don't see any buttons on this applet.

i also recompiled mozilla with java env to r2 set.
