public class HelloWorld extends SimpleGame{

   public static void main(String[] args)
   {
      String path = System.getProperty("java.library.path");

[b]//thats the path!???

I did global library's with the jar's and classpaths.
I don't know what else to do, thank your for your help!

I think the root of the problem is that its not finding the native libraries for lwjgl (not the JAR includes) - I dont use ant or Maven so not sure if they are complicating things for you.

 

This is probably the most common problem round here, and as such - try searching the forum for "no lwjgl in java.library.path" theres currently 9 pages of results for that :slight_smile:


3

i searched in the forums and tried much hint's but its hopeless.



I tried to compile on the command line without ant, but its the same.



Does anyone know more'

In your output, it seems to have a : as the separator in the class path ?

I don't know if thats some kind of Mac specific thing or other problem, but that will cause the error you are seeing on a windows box.



'-Djavac.library.path=/Users/hucky/java/Jme/lib/lwjgl/native/macosx:/usr/local/lib:/Users/hucky/java/Jme/lib:/Users/hucky/java/Jme/lib/lwjgl'



If its like that in your ant build script, try changing the : to a ;

5

this is a mac osx thing, in windows u use ; on mac :



i linked the libraries now on the filesystem to java, its a bad solution but it works!


6

ok, i found the solution:

its not:

-Djavac.library.path=path_to_native/macosx/

it has to be:

-Djava.library.path=path_to_native/macosx/



thx for your help!
