LightZone 2.4 -- no error messages and no lightzone! :(

[Noah Pritikin]

Hey everyone,

I'm getting unexpected results from v2.4... Just got a new Core2 Duo
box and trying to get LightZone to work on it.  I've read through some
of the other problem-discussing threads for v2.4, but nothing seems to
apply here...

Here's what happens fresh "out of the box":

user@host$ ~/LightZone/LightZone
testing JVM in /home/user/LightZone/jre ...
testing JVM in /usr ...
user@host$

I get my prompt back immediately--nothing happens... I check `ps aux |
grep -i Light` to see if there's any after-running processes, but
there aren't any.

Ideas?  Without errors, this is kind weird/hard to debug.  :-P  Any
help is much appreciated!!!

Thanks in advance,
Noah

(btw, is there an IRC channel that has people in it that use LightZone?)

Heh, so after working more on my own problem I did figure out one
(obvious) thing:  I should make sure I have the dependencies to run
2.4 -- java!  I installed java >= v1.6 and re-ran lightzone.  I got
the splash screen/image and then an error occurred:

java.lang.UnsatisfiedLinkError: /home/noah/LightZone/libLCFileUtil.so:
/home/noah/LightZone/libLCFileUtil.so: wrong ELF class: ELFCLASS32

I'm assuming this has something to do with the fact that it's not a
64-bit module?

Any help would be great! I'm getting closer...

Thanks,
Noah

Another obvious lesson:  check the archives for related problems! :)

I'll give that a shot.

Thanks,

Noah, have you seen this one?

http://kast-dev.com/pipermail/lightzone/2007-May/000338.html

This seems to be a generic fix for both AMD and Intel 64 bit systems,

Dan,

Yea, I saw that before... I don't think that's exactly my issue, but I
tried it anyway--didn't work right.  Thanks for the pointer though.

I got the 32-bit version of java 1.6 installed and tried to launch
LightZone again... now I'm back to the old not-displaying-anything
problem, which just drops me back at the command prompt.

Switching freely between jvm's, the 64-bit one gives me more progress,
but does end up failing because it can't link the 64- and 32-bit
modules together (aka, "Wrong ELF class" stuff).

erikvandervelden:  I'm also running the Gentoo AMD64 build, so how did
you get it to work?  I have emul-linux-x86-java and sun-jdk both
installed and have tried both unsuccessfully.

Thanks,
Noah

Dear Noah,

It looks like LZ is not detecting the JRE that it comes with, and that while your system installed JRE is OK, something about it causes a failure.  I had a similar problem a little while ago, also on Centrino Duo.  I'm attaching a copy of the solution that worked for me.  I hope it helps you too.

Regards,
Philip.

Thank you Dan and Paolo. 

Yes, adding the line "-client KNOWN" above the existing line "-client IF_SERVER_CLASS -server" does the trick.  Incidentally, for the record, I'm running an Intel Centrino Duo machine, so the problem is not limited to the AMD 64.

Regards,
Philip.

Philip,

While the 'directory copy and rename' fix will work, the easier fix for the AMD 64 boxes seems to be Uwe's original fix; I'll repeat it here so it will be available for those using 2.4 without having to search as much:

In your LightZone folder, drill down to: LightZone\jre\lib\i386 and open the file jvm.cfg (you may have to give yourself write permission depending on your user level).

add the line "-client KNOWN" without the quotes below the lines commented out with the #s. 

Save the file and give LightZone another try at starting,

Dan

Phillip,

Thanks for the input... although, Dan pointed me to that thread
earlier.  I tried that without success.  :-(

Here's the uncommented contents of ~/LightZone/jre/lib/i386/jvm.cfg:
--------------------------START--------------------------
-client KNOWN
-client IF_SERVER_CLASS -server
-server KNOWN
-hotspot ALIASED_TO -client
-classic WARN
-native ERROR
-green ERROR
-------------------------END-------------------------------

When I go ahead and try the launch again, this is what I get:

[....]$ ./LightZone
Preparing JRE ...
[....]$

Again, I'm not a programmer, but perhaps the java install is not in the
path variable? I'm having a similar problem with a program called
ThinkingRock: it cannot see my java install and is falling back to a
more basic setup.

Hi Noah,

Strangely enough for me it seem to work 'out-of-the-box' with the included jre.
I did not change directory names or did anything to the jvm.cfg !
two questions.

1) does the script find the correct (included) jre?
Maybe try "sh -x LightZone" and see where it fails.
I've included my output as an attachement. LightZone is installed in /usr/local/lib/LightZone
with the binary in /usr/local/bin symbolically linked to the installed binary.

2) can you run the included jre?
<lightzonedir>/jre/bin/java -version
For me this gives:
java version "1.6.0_01"
Java(TM) SE Runtime Environment (build 1.6.0_01-b06)
Java HotSpot(TM) Client VM (build 1.6.0_01-b06, mixed mode, sharing)

I think it should also work with app-emulation/emul-linux-x86-java, but I've never tried this.

Good luck, Erik

Dan, 
 
Yea, I saw that before... I don't think that's exactly my issue, but I 
tried it anyway--didn't work right. Thanks for the pointer though. 
 
I got the 32-bit version of java 1.6 installed and tried to launch 
LightZone again... now I'm back to the old not-displaying-anything 
problem, which just drops me back at the command prompt. 
 
Switching freely between jvm's, the 64-bit one gives me more progress, 
but does end up failing because it can't link the 64- and 32-bit 
modules together (aka, "Wrong ELF class" stuff). 
 
erikvandervelden: I'm also running the Gentoo AMD64 build, so how did 
you get it to work? I have emul-linux-x86-java and sun-jdk both 
installed and have tried both unsuccessfully. 
 
Thanks, 
Noah

Erik,

Thanks a bunch for your help.  I'm not sure why or how, but when I
just executed "sh -x LightZone" it worked!  I checked to see if I had
the modified jvm.cfg or not, and I did.  So, just to test it, I took
out that extra line ("-client KNOWN") and tried "sh -x LightZone"
again--didn't work.

I've rebooted a couple times since I was having issues, so I wonder if
something in my environment was screwy...  anyway, it's working now on
the jre that comes with lightzone.

I uninstalled emul-linux-x86-java since I don't need it anymore.

Thanks again!

-Noah

p.s. LightZone 2.4 is AWESOME!
