Java, Eclipse Ide and 32 bit emulation

Hi,

Has anyone got java (sun jdk 1.4.2_03) working in 32 bit emulation under an amd64 install?

I set up my 64 bit install expecting to be able to do java development and read that black down had a 64 bit version of 1.4.2. That ran fine but then trying to get any ide to work was a problem. IntelliJ uses its own jre to start up and I couldnt work out how to change that. Eclipse compiles its own binary but its still an elf 32 bit binary and was giving me not found errors.

I then installed the 32 bit emulation thinking it was the answer. I then tried the sun jdk again and intellij and was having some wierd problems about locales and downloaded files being corrupted.

If anyone has had success in this area please email me as I would love to get this going but for the moment I am going back to a 32 bit install.

Thanks,
Carl.

Hi Carl,

I had the same Problem with IntelliJ Idea. You must download the generic unix version without a jre bundled. Then you must build a custom jre. Use the blackdown jdk and copy the folder jre to your IDEA_HOME. Then you must add some files. See Install.txt in your IDEA folder.
Now you have to turn off the idea jre version check. Simply add -Didea.no.jdk.check=true to your jvm arguments in idea.sh.

Ok, IDEA should work in case you have a valid key.

Eclipse still doesn't work on my linux box, too. But I am working on it :-)

. I think, it has something to do with gtk/motif libaries, because I get error messages from bothe version that they cannot find these libaries. Maybe an 32bit compalibilty issue?

regards, Volkher

I'm not sure if they work for this, but there are, last I checked, gtk 32-bit compatability libraries...though I believe there is also an eclipse source distribution that one could try.

Yeah, there are some patches for the gtk2 version to make swt 64bit compatible. I am working on an ebuild for this. Does anybody know why the current ebuilds want to emerge kde before emerging eclipse even if you use gnome?

volkher: I am a bit of an ebuild novice, but getting a version of eclipse running on amd64 is very much of interest to me.

If you would like any assistance (whether it be testing or anything else) please feel free to contact me.

Thank you! Until now, I have tried various ideas, but nothing worked. My first goal is a running eclipse on amd64. With that, the writing of an ebuild should not make so much problems. But therefore, we need a running eclipse! In the last few days, I have made some experiences:

Try this link:http://people.redhat.com/faltaous/eclipse/ There is a patch for the java files of the swt libary. However, I get error messages that eclipse could not find the native swt libaries. I think they have to be recompiled, too. But that is not so easy! When I use the swt release for eclipse 2.1.2, it complains:

Well, I had a go trying to get eclipse to run using the x86 emulation libraries, and Sun JDK 1.4.2 (32 bit).
No luck. It appears to be complaining about the theme engine, and looking in the lib32 directories, it appears that they have not been provided as part of the gtk emulation package.

Also tried the motif build which didn't go much better.

Just noticed that amd64 builds of eclipse look like they are starting to appear on the download pages now. I'm going to give I20040309 a try.

That integration build does not seem too happy either:

JVM terminated. Exit code=13
/home/myuser/opt/j2sdk1.5.0/bin/java
-cp /home/myuser/opt/eclipse/startup.jar org.eclipse.core.launcher.Main
-os linux
-ws gtk
-arch amd64
-showsplash /home/myuser/opt/eclipse/eclipse -showsplash 600
-shared /home/myuser/opt/eclipse/eclipse -shared 530010
-data /home/myuser/workspaces/test
-vm /home/myuser/opt/j2sdk1.5.0/bin/java
-vmargs
-cp /home/myuser/opt/eclipse/startup.jar org.eclipse.core.launcher.Main

Tried it with blackdown jdk and got the same results.

I had to remove the .eclipse config file in my home directory and then I was able to get the latest integration build to work.

Lucky for me, I didn't have any active projects on this machine yet, not sure how to handle that, maybe import them from the workspace after you start it?

Build I20040310 does indeed seem to run.

It failed to start up correctly the first time I ran it, but subsequent attempts have all started ok.

I think it's gonna be better to give the eclipse developers some more time to get the amd64 build stable, and then look at modifying the existing ebuild to get this in portage.
