a new "special" person joins in!

Okay - I am using Linux with Net Beans 3.5.1 and have just seen this lwjlg thingy and and intrigued into if it is any good - if so, I may use it for my final year project as part of my Degree.

Thing is - I cant get it to work! lol.. I have copied the "lwjgl.jar" file into my java folder and added it into NetBeans and it compiles with no errors (that alone only took me 1 hour!) However, on running the program I get the follwing error:

Exception in thread "main" java.lang.UnsatisfiedLinkError: no lwjgl in java.library.path
       at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1491)
       at java.lang.Runtime.loadLibrary0(Runtime.java:788)
       at java.lang.System.loadLibrary(System.java:834)
       at org.lwjgl.Sys.initialize(Unknown Source)
       at org.lwjgl.Sys.<clinit>(Unknown Source)
       at org.lwjgl.Display.<clinit>(Unknown Source)
       at RainingDay.init_lwjgl(RainingDay.java:135)
       at RainingDay.<init>(RainingDay.java:74)
       at RainingDay.main(RainingDay.java:466)

I read somewhere that this can be caused if I dont compile it.. Now, from a complete newbie at work here for this and a pretty much begginer at Linux - what EXACTLY do I have to do?

I can normally figure things out myself by pointing, clicking and analysing the result (as either "IT WORKS!! HELL YEAH!!" or "Oh *expletive* " ).

So - to sum up my post - how the heck do you install this thing! lol

click me

Basically, you need to pu liblwjgl.so (and his brothers) into your java path

Its alive!!!!!!!!!!!!!!!!!!!!!!!!!!!

If you don't like installing the binaries system-wide, you can place them anywhere you like and use -Djava.library.path=./lib to point to them.

Portability question now..

I am developing my final year project now in this language and would like to say first: It rocks!! I spent an entire summer holiday (about 4 months) with concerted effort on J3D.. and got NOWHERE.. in one night between me and a mate managed to grasp the basics in this language!!

Now, I am making my project in Linux as I want something stable and fast.. However,  my friends tend to use Windows and if I want to run it on their PC, do I have to install the DLL files and lwgjl.jar onto their PC?

I made a JAR file up with just my two classes and when I ran it on my PC, it couldn't find the lwjgl.jar classes so I have added the lwjgl.jar classes into my JAR file.. However, when he runs it he said he got a fatal exception or something.. implying to me he might need the DLL files..

If so - is it possible to dump the DLL's into my JAR file too?

Thanks

Nick

You can stuff themm in a jar and use java web start. That way it will be easy to run nin linux and win32 alike.

I have just tried to run lwjgl on my Uni PC's.. Unfortunatly, my uni does not grant any of its user Admin privaledges, meaning I cannot copy the JAR file or the Windows DLL files into the JDK folder.

In a thread about this - someone mentioned setting the class path. I tried that line and get some java error about class not defined error. Eventually I got

javac -classpath 'M:\Project'

to work. Unfortunately - it still wont compile.

What exactly do I have to do to get this to work? Is there ANY way I can just dump the DLL's and the JAR file and my java/clas files in one folder and run Java with some kind of arguement?

Thanks for all your help peeps..

Nick

BTW: Just so you lot know - I'm making a networkable Air Hockey game.. Its looking "ok" right now - I need to work on lighting.. If anyone has any usefull working tutorials on Lighting in LWJGL I would GREATLY appreciate them!!

Thanks again guys..

But the offer still stand for anyone who knows of any working LGJWL 0.7 Lighting Tutorials.. I have tried some - but my brain went "pop".. ;-)

Cheers!
