UnsatisfiedLinkError: no lwjgl in java.library.path

niq · January 10, 2012, 2:56pm

Hi folks,

I have been following this forum as a guest for a while …
And I would like to join in

I’m Dane, running Java in Eclipse, using Ubuntu (Linux).
Rather new to Java, but I have been coding for some years.

I have recently installed Slick (+lwjgl+phys2d) as mentioned by some of you.

Then I finally made a program, that was allowed to run on my wifes computer too (Tetris ;))
But when making a JAR file and trying to run it, I get the same error as GustavXIII.

That is when I create an export to Java/Runnable JAR-files, it gives me a:
“no lwjgl in java.library.path”

Then i tried to make a “normal” Java/JAR-file export, which results in an:
“Exception in thread “main” java.lang.NoClassDefFoundError: org/newdawn/slick/state/StateBasedGame”

As said, I’m new to Java, and I’ve spend last night and most of the day today (it’s almost 4pm in DK) making it work.
I hope that someone has a solution, or maybe a hint for me

Regards
niq

Maybe use Java Web Start as it is explained here in Slick Wiki:
http://slick.cokeandcode.com/wiki/doku.php?id=webstart

GustavXIII · January 10, 2012, 4:46pm

If I disable FModEx then I can start my game from the jar.
But I dont know where the error is with FMod…

@gouessej I will try it tomorrow.

@niq Ive done the 2 steps from here:
http://lwjgl.com/wiki/index.php?title=Distributing_Your_LWJGL_Application
I’d made the Manifest and the bat.
Now lwjgl work so you could try it too.

niq · January 10, 2012, 7:01pm

Hi again

I would like to thank you for your help

But I could not get it to work though (the manifest thing) but I was lead to this page:
http://lwjgl.com/wiki/index.php?title=Distributing_Your_LWJGL_Application
where I found a solution which seems to work … using JarSplice.

I downloaded JarSplice from ninjacave.com/jarsplice

Now my wife can start playing Tetris

Regards
niq

GustavXIII · January 10, 2012, 7:07pm

I tryed JarSplice too but it always say after I execute the Jarfile: “FATAL ERROR, corrupted File” oO"
Maybe I downloadet a version with errors…

gouessej · January 10, 2012, 7:13pm

Ok. You can have a look at the JNLP file used by the game “Flesh Snatcher” in the showcase section, it relies on LWJGL. Just replace the line handling LWJGL by the line handling Slick & LWJGL at the same time, replace its JAR by yours, sign all JARs with the same signature and upload your JAR and your JNLP file onto a server.

niq · January 10, 2012, 7:51pm

@GustavXIII
The first JAR-file I created was also corrupted

This time I followed this video on “youtube”

It seems to be working

gouessej · January 10, 2012, 8:24pm

niq, double-clicking onto a JAR file under Windows opens WinRar by default whereas it works fine on Mac. That’s why I advise you to use Java Web Start, an applet or another installer.

niq · January 10, 2012, 8:58pm

@gouessej
Thanks for your advise
I’ll be looking at that next time I have to deploy a program …
I also saw you can change .JAR files to .EXE (Win32) … I didn’t read further than that, and don’t know more about it.
But would that be recommendable too? … I’m aware that it doesn’t run under other systems.

Regards

gouessej · January 10, 2012, 10:01pm

You’re welcome. I would like to see your game(s) in the showcase section ;D Let me know whether you’re ready and I will try to help you as much as I can.

You obviously know this solution is not cross-platform. Some programmers here prefer hiding Java and use tools to perform deep native integration. I advise you to look at this, this sums up the situation pretty well:

Excelsior JET makes very zippy exes, but costs mui dinero, and gcj is a toy that’s slower than hotspot. Launch4j may be more what you’re looking for.

ra4king · January 10, 2012, 11:36pm

Launch4j is an amazing tool which all Java programmers SHOULD be using. I also recommend that.

GustavXIII · January 11, 2012, 10:21am

Ive tried Launch4j but I get an error. I have the JRE!

And I dont know why I get the error with FModEx then I use my .bat.

niq · January 11, 2012, 8:41pm

Hi gouessej and you other folks

Thanks for advises and encouragement
I’ll be looking at Launch4J soon … Now I first have to make something worth deploying
The Tetris game was from Spiegel’s tutorial on one of the Slick pages, and not my own creation …
Now I have Slick, I don’t even know which game to start coding :-
Maybe I should be playing a little with new graphic commands and see if I get any good ideas …

Thanks again and regards

GustavXIII · January 14, 2012, 1:27pm

I cant fix FMod.
What are you guys using to play Music and Sounds and did it work with .jar?

niq · January 16, 2012, 7:24pm

Hi GustavXIII

I don’t know about FMod, and have only a little experience with sounds in Java until now.
I use Slick to play music and sounds in my game … seems to work fine - also in Jars (with the remark that all files in my project is in the src directory).
It’s just a slow starter (3 seconds for a 3MB ogg music file).

I hope you can use this information

Regards

Cero · January 16, 2012, 7:40pm

FMod works fine, just do it right ;D

Slick uses LWJGL which uses OpenAL - you can use that too

GustavXIII · January 17, 2012, 10:56am

Then tell me how. I put every .jar and .dll in the directory??
And Init.loadLibraries does not work.

I will try using Slick to play music thanks.

EDIT: OK it work with Slick I dont need FMod xD"

ctomni231 · January 18, 2012, 12:37am

Hey Gustav and other members who are having this problem.

I’ve been using Slick for a while and have been using it to package .jars. The error is caused when the natives are not in the same directory as the .jar. If you bundled them with the .jar, this error will keep appearing.

There are a lot of natives bundled with Slick. The fastest way is to find the natives that are for your specific OS and put your .jar in a separate folder along with the natives. A quick example for Windows…

I just piled all the natives into a folder called native.

native/natives-win32 (Windows Natives)
native/natives-linux (Linux natives)
native/natives-mac (Mac natives)

Then I put that folder in the same folder as the .jar

blah.jar, native(DIR) [contains the natives]

Then put this line when running Java…

java -Djava.library.path=native\natives-win32;lib\native\natives-linux;lib\natives\natives-mac -jar blah.jar

Of course, you can always use the bundling programs suggested if you wanted to package it as a single .jar. But hopefully this helps.
