Java on Gentoo?

[mikenemat]

Has anyone had any luck getting Java compiled on Gentoo?

I've tried tons of different methods, I cant even get gcj (GCC 4.3 unmasked with USE="gcj") to compile

Can you be a little more specific?  I haven't tackled that, yet.

What kernel are you using?  What version of Java?

[Raúl Porcel]

Indeed, be more specific, also join #gentoo-java and #gentoo-embedded @ irc.freenode.net and you could get some more help

[karurosu]

Any success with this?
I would like to know if there is a way to get java 1.6 running in gentoo.

Thanks.

I would like at least to use a JRE on it. Someone tried Kaffe?

Have you tried building the IcedTea versions?

If nothing else there's a lot of work going on with the Zero/Shark version to keep ports fresh and a decent HotSpot for ARM.

I'm currently using Sun's 'embedded' JRE on Ubuntu on the plug, which works well, but I hope to be able to switch to the Zero/Shark JVM for some uses soon.

Boy, have I -- and with baby steps success.  I still am gated, see gcc gnu Bug 42409

• circular dependencies for install of Gentoo ARM5: http://icedtea.classpath.org/bugzilla/show_bug.cgi?id=387
• Couldn't get past a Fortran install, resolve to limiting to GCC:  http://icedtea.classpath.org/bugzilla/show_bug.cgi?id=388
• libgcj_bc.so.1 dependency causes gcj to fail: http://gcc.gnu.org/bugzilla/show_bug.cgi?id=42405
• org.eclipse.jdt.internal.compiler.batch.GCCMain not found: http://gcc.gnu.org/bugzilla/show_bug.cgi?id=42409

Xerxes built me a binary of the JDK that I have used with some success, see his site at:

http://labb.zafena.se/

In particular try:

http://labb.zafena.se/shark-testing/armv5/

and give some feedback!

Also maybe join the zero-dev mailing list at IcedTea: it's pretty low volume.

Here are the results of my attempt.  I visited http://labb.zafena.se/shark-testing/armv5/

and downloaded 5nov-j2sdk-image.tar.gz and gunzipped and tarred it.  Here's there error message I get when testing for the version:

Code:

plug 5nov-j2sdk-image # ./bin/javac -v
dl failure on line 696Error: failed /usr/local/src/j2sdktest/5nov-j2sdk-image/jre/lib/arm/server/libjvm.so, because /usr/lib/gcc/armv5tel-softfloat-linux-gnueabi/4.1.2/libstdc++.so.6: version `GLIBCXX_3.4.9' not found (required by /usr/local/src/j2sdktest/5nov-j2sdk-image/jre/lib/arm/server/libjvm.so)

I'm on Gentoo.

OK, sorry that didn't help.  Gentoo is a mystery to me...  I just about understand Debian/Ubuntu/RedHat!

But do try sending of of the guys on that project an email and see if they have any suggestions.
