WWJ problem on Ubuntu

[nlneilson]

New Notebook computer and having problems on Ubuntu 11.04.

The demos and apps work fine in Win7.

In Ubuntu the demos and apps crash with about the same errors.

# A fatal error has been detected by the Java Runtime Environment:
#
# SIGSEGV (0xb) at pc=0xb7807424, pid=2053, tid=2249218928

Aborted

In System Monitor "java sleeping 100% CPU" (one core of 4)

Ubuntu is dual boot. VMware doesn't support OpenGl, VirtualBox has been downloaded but not tried yet.

The demos open and shows the Marble OK then locks up and eventually crashes.

This has an AMD 64bit Quad Core but running WWJ as 32bit.

I have two other 32bit Notebooks and a 64bit Desktop that run WWJ in Windows and Ubuntu OK.

Can you attach the crash log (hs_err_pid2053.log)? My first suspicion is a problem in the graphics driver. Have you updated the driver? Is it the same card and driver as your other Linux machines that are working?

[nlneilson]

Here is the .log file, the forums limit for attaching I have maxed out so had to transfer that to another computer with FileZilla to upload it.
http://www.nlneilson.com/wwposts/hs_err_pid2053.log

Each computer has a different video card/driver.

The new computer has ATI Radeon HD 4250 graphics
When installing Ubuntu 11.04 there was a pop-up for the 4250 so that was installed.

The 64bit box has an AMD chip and Nvidia GeForce 6150

edit: This is the WWJ app I am trying to run and the .log file is from:
http://www.nlneilson.com/nlnww.html

I don't know if there is or where a .log file for the demos is at.

[nlneilson]

I don't know if this is related to the Ubuntu problem but in Win the NLNww.jar app is usually run with a bat file to set the heap space:
java -jar -Dsun.java2d.noddraw=true -Xmx512m NLNww.jar
The AMD Phenom II Quad Core apparently takes care of that and shares the load when clicking the .jar file and runs OK, trying to run the .bat file returns:
C:\NLN\NLNww>java -jar -Dsun.java2d.noddraw=true -Xmx512m NLNww.jar
Exception in thread "main" java.lang.UnsatisfiedLinkError: C:\NLN\NLNww\jogl.dll
: Can't load IA 32-bit .dll on a AMD 64-bit platform

On Ubuntu there is no comparable error with the .bash file:
cd ~/NLN/NLNww
java -Xmx512m -Dsun.java2d.noddraw=true -Djava.library.path=. -jar NLNww.jar
or variations of this.
clicking the .jar directly nothing happens even with execute permission.

The "Can't load IA 32-bit .dll on a AMD 64-bit platform" indicates that you're running on a 64 bit OS and using a 64 bit JVM, but your jogl.dll is for a 32 bit OS. If you need a 64 bit version of JOGL you can find it here: http://download.java.net/media/jogl/...jsr-231-1.1.1/. Alternatively, you can use a 32 bit JVM on a 64 bit platform, and then the 32 bit JOGL library will work.

I'm afraid that I wasn't able to learn anything from the error log in your previous post. I still suspect a problem/bug in the Linux graphics drivers on this machine.

[nlneilson]

The only time "Can't load IA 32-bit .dll on a AMD 64-bit platform" came up was on Win7 when trying to run the app with the .bat file. Clicking on the .jar it ran OK.
I had installed Eclipse 32bit which may have pulled the 32bit Java in.
Also when I initially run Win7 it asked to update the JRE.
Or maybe this computer was set up by HP to run either 32 or 64bit Java.

Ubuntu 11.04 was installed with the 32bit ISO.
I downloaded Eclipse Indigo and running the WWJ app from the IDE shows the same
error as trying to run the the .jar with a .bash file:

# SIGSEGV (0xb) at pc=0xb780
# Java VM: OpenJDK Server VM (20.0-b11 mixed mode linux-x86)

The app hangs, cannot be closed even if Eclipse is closed and System Manager shows the jogl .jars are still running. After several minutes the app closes by itself.

There has not been a problem shown of 32bit v 64bit on Ubuntu.

With a Google search found something about SIGSEGV and Server VM.
Apparently it should be a regular VM (whatever that is) rather than Server VM but that was back in 2009.

I just upgraded the 64bit box from Ubuntu 10.10 to 11.04.
Now it doesn't work, driconf does not recognize the Nvidia video.
javax.media.opengl.GLException: DXTn compressed textures not supported by this graphics card

Will stick with Windows for now on the computers with problems.

Hi Neil,

I am not sure if you have realised that you can use JNLP's to perform platform detection, native library choosing and launching without a webserver. Try this option if you are supporting lots of platforms.

Cheers,

whatnick.

Hi whatnick

I have never used JNLP's.
I have no idea how that would be done.

I just removed Ubuntu 11.04 and installed 10.10, apparently there are a lot of problems on the latest version with driconf and OpenGL apps with many video cards.

Installed driconf and it recognizes my video, installed the OpenJDK.

The demos run but just shows a white globe, the layer list, controls, etc are OK.

My app runs without the SIGSEGV error.
It shows a white globe and the rest seems OK same as the demos.
I get this:

unsupported texture format in setup_hardware_state
failed to validate texture for unit 0.

Have not researched that yet.

Neil, I would suspect your libGL.so.* driver. From your log file I see that your Ubuntu installation is using the /usr/lib/fglrx/libGL.so.1.2

I just installed Ubuntu 10.4 x64 and I have the /usr/lib/mesa/libGL.so.6.0.12092.670880

I had many issues with fglrx, especially with the graphics performance.

Did you mean 11.04 rather than 10.04?

I am attempting to run everything as 32bit as most 64bit computers will run that as well as the 32bit computers.

Almost all of my development is in Windows but want the apps to be able to run on Linux, at least Ubuntu.

When I update I just replace the gov directory, have any of the jogl .so files been changed?
