no gluegen-rt in java.library.path

[Logan Williams]

Hello,

I am trying to compile a JAR file in Eclipse and run it on a different system. I can compile the JAR file, and Eclipse says that it is packaging all required libraries into that file. When I try running it on the second system however, I get this response:

I'm compiling the JAR on Mac OS X, and moving it to a 64-bit linux system. I thought that it might be fixable by using a 64 bit version of gluegen-rt, so I duplicated the Eclipse project, and replaced the original gluegen-rt with the amd64 version I downloaded from jogl's website. The recompiled JAR however, returned the same error.

Does anyone have any idea what could be the problem here, or what other avenues I can explore to fix it? Any help would be sincerely appreciated.

Thanks,
Logan Williams

Do a search for "no gluegen" or "no jogl". This has been covered in several threads.

Under Win OS jogl.dll and jogl_awt.dll needs to be in the same directory as your WWJ app.jar.
This was using Eclipse and fatjar.

On Linux Ubuntu I just installed the jogl package.

Some have been able to set the path in the manifest, on the command line or whatever.
I didn't have much luck this way but didn't take the time to learn what is necessary.

[Logan Williams]

But I already have gluegen-rt.jar and jogl.jar in the same directory as the jar file I'm trying to execute...

[nlneilson]

You need the .dll files.

edit: Try copying all the jogl related files to the directory your .jar is in then deleting a few at a time to see what is required. If I remember correctly the worldwind.jar needs a few more than just the two .dll files mentioned.

[Logan Williams]

.dll files on Linux?

[nlneilson]

No

Linux uses the .so and maybe others. I just installed the jogl package there.

Trying on different computers there was a problem mixing in the 64bit. Try just using the 32bit on Linux.

edit: There is also a problem using the 64bit java, whether Sun's or openJava. You can do a search on the internet to find this. Stick with the 32bit java and jogl on Linux.

I have found that the easiest solution to this problem is to install the jogl package from synaptic (Ubuntu) or yum (Fedora). I know this should works as is, but there seems to be a problem with java finding the jogl native libs when you run the jnlp in java.

[nlneilson]

Here is a link to another thread where others have added posts
http://forum.worldwindcentral.com/sh...ghlight=ubuntu

As mentioned in post #2 doing a search for a problem is usually the easiest and fastest way to find a solution or solutions to a problem.

Note: I have found WWJ is slightly faster in Linux in some situations than it is in Windows.

I've found the solution for this problem, when the project is compiled in Eclipse.
Just do this:
-> Right Click the Project folder
-> Run As
-> Run configurations...
-> "Arguments" tab
-> VM Arguments:
-> Insert: "-Djava.library.path=$path:."

I've been having this problem and to compile I would simply
use the shell, only until the debug mode was really necessary.

This is working fine for me.
Hope it might help someone!

I've also had that message and found which option I was lacking:

After I added (jogl.jar and) gluegen-rt.jar at project>properties>JavaBuildPath>Librari es
I still had to set one more option on gluegen-rt.jar: In the same menu expand the gluegen-rt.jar, which I had added. There the entry "Native Library Location" had to be set.

then the eclipse-play button worked
