WWJ problem on Ubuntu

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?

My previous posts was related to Ubuntu 10.04 64-bit.
I'm installing Ubuntu 11.04 32-bit right now and once it is done, I will run those commands on it.

Those commands retrieve newest World Wind Java SDK release 1.2.
I do not know what version of WWJ SDK you have, but let's just run tests in the separate folder.

[nlneilson]

I replaced the gov directory with the one from SDK 1.2

I tried some of the commands from post #10, up to the 64bit stuff, I would like to run WWJ 32bit.

sudo apt-get install ant1.8
returned
Unable to locate package ant1.8
Couldn't find any package by regex 'ant1.8'

The rest went OK, interesting way of installing WWJ, seemed to have installed on both computers.

sudo apt-get install ant 1.8
with space between ant and 1.8
seemed to work, several lines had ...is already the newest version where I installed Eclipse that installs ant, on both computers it ended with "Broken packages"


I removed Ubuntu 11.04 and replaced with 10.10 on the new Notebook, I can change that back easy enough but also have a 64bit box with 11.04 32bit still installed.

[garakl]

I'm in the middle of testing on Ubuntu 11.04 x32
I will post updated list of commands, because it turns out on 11.04 there is no ANT 1.8, but there is ANT 1.7.
Thus, the correct command will be
sudo apt-get install ant1.7

[nlneilson]

Good! sudo apt-get install ant1.7 works
An interesting side note on this is a Toshiba 32bit with Intel 945GM was such a problem until a recent driver update I bought an HP with AMD,

The Toshiba now runs OK on Win XP and also Ubuntu 11.04.

Here is a list of linux commands I used to install and run WorldWind application on fresh Ubuntu linux 11.04 32-bit with OpenJDK 6.

sudo apt-get install ant1.7
sudo apt-get install openjdk-6-jdk openjdk-6-jre-headless openjdk-6-jre-lib

cd ~/Desktop
mkdir WorldWind
cd WorldWind

## get latest World Wind Java SDK release
wget -O worldwind-1.2.0.zip http://builds.worldwind.arc.nasa.gov/worldwind-releases/1.2/builds/worldwind-1.2.0.zip

## extract World Wind SDK
unzip worldwind-1.2.0.zip

## get and extract JOGL natives for linux 32-bit 
wget -O gluegen-rt-natives-linux-i586.jar http://worldwind.arc.nasa.gov/java/jogl/webstart/gluegen-rt-natives-linux-i586.jar
wget -O jogl-natives-linux-i586.jar http://worldwind.arc.nasa.gov/java/jogl/webstart/jogl-natives-linux-i586.jar

unzip jogl-natives-linux-i586.jar 
unzip gluegen-rt-natives-linux-i586.jar 

## build World Wind 
ant worldwind.jarfile
ant worldwind.extensions.jarfile

## start World Wind 'InstallImageryAndElevationsDemo'
java -Xmx1024m -Dsun.java2d.noddraw=true -cp worldwind.jar:worldwindx.jar:jogl.jar:gluegen-rt.jar:gdal.jar -Djava.library.path=`pwd` gov.nasa.worldwindx.examples.dataimport.InstallImageryAndElevationsDemo

I had to make two modifications to the build.xml file:

1. add encoding="ISO-8859-1" option to the javac section.

<javac encoding="ISO-8859-1" srcdir="${worldwind.src.dir}"

2. openjdk on 32-bit platform does not install plugin.jar, so I had to use the plugin.jar that comes with WWJ
Replaced

<pathelement location="${java.home}/lib/plugin.jar"/>

with

<pathelement location="plugin.jar"/>

There is defenitelly something wrong with libGL driver on Ubuntu 11.04 32-bit.

When I frist run the WWJ application, both my virtual Ubuntu machine (on Parallels) and the host (mac) did crash. I had to reboot host machine.

My Ubuntu installation (as a virtual machine under Parallels, which has best OpenGL 2.1 support comparing to VMWare or VirtualBox)
has /usr/lib/mesa/libGL.so.6.0.12092.670880 and a standard set of aliases to it in the same /usr/lib/mesa/ folder:
libGL.so -> libGL.so.1
libGL.so.1 -> libGL.so.6.0.12092.670880

Since Parallels installs their own libGL driver, I recreated aliases in the standard /usr/lib/ location like this:

cd /usr/lib
sudo ln -s /usr/lib/parallels-tools/tools/prltools/xorg.7.1/usr/lib/libGL.so.1.0.0 libGL.so
sudo ln -s libGL.so libGL.so.1

Right after this I was able to run WWJ app without any problem.

Since you do not run Ubuntu as a virtual machine, let's see what libGL.so files you have installed.

find /usr -type f -name libGL\.so*

Also, you could use this command to see which OpenGL Mesa drivers are available

sudo apt-cache search OpenGL mesa

Install Mesa DRI & GLX modules

sudo apt-get install mesa-utils libgl1-mesa-dri libgl1-mesa-glx libgl1-mesa-swx11

Search for libGL.so.* library again to make sure you have Mesa modules installed and the version (mine was /usr/lib/mesa/libGL.so.6.0.12092.670880)

find /usr -type f -name libGL\.so*

and re-create libGL.so and libGL.so.1 alaises in the /usr/lib folder

cd /usr/lib
sudo ln -s /usr/lib/mesa/libGL.so.6.0.12092.670880 libGL.so
sudo ln -s libGL.so libGL.so.1

Let me know if you have better luck with Mesa module.

This is on 10.10
I will go over the steps again then try and run something.

I will also do this on the computer that has 11.04

It looks like the degree symbol and others are causing errors at least on 10.10
If these are all in comments I don't understand why the build would fail.
In Eclipse with ant that just shows a warning.

I will try this on 11.04

I didn't know VMware worked OK with OpenGL in Windows.
I downloaded VirtualBox but have not tried that yet, I will look at Parallel later.

Same build error as above on the computer with Ubuntu 11.04.
trying

java -Xmx1024m -Dsun.java2d.noddraw=true -cp worldwind.jar:worldwindx.jar:jogl.jar:gluegen-rt.jar:gdal.jar -Djava.library.path=`pwd` gov.nasa.worldwindx.examples.dataimport.InstallImageryAndElevationsDemo

shows the WWJ frame and layer manager OK but no globe and shows this error:

Jul 21, 2011 3:48:56 AM gov.nasa.worldwind.layers.TextureTile initializeTexture
SEVERE: Exception attempting to read texture file 
javax.media.opengl.GLException: DXTn compressed textures not supported by this graphics card
	at com.sun.opengl.util.texture.Texture.checkCompressedTextureExtensions(Texture.java:987)

This computer ran WWJ apps OK on an earlier version of Ubuntu and has a Nvidia graphics.

I installed driconf but now it doesn't recognize the Nvidia graphics.
It may be that Ubuntu is trying to eliminate the need for driconf but have not gotten the graphics issues fixed.

The 32bit computer that required driconf before does not need it now and runs the WWJ apps OK on 11.04.

Or it could be caused by the build error but beginning to doubt that.
