I just don't get it....
I'm using netbeans7.4 on a 64 bit win7 pc, i have an amd hd6670 that supports opengl. I've successfully added lwjgl libraries to my project but when i hit run this message pop up: java.lang.UnsatisfiedLinkError: no lwjgl in java.library.path
I've tried setting the VM option to -Djava.library.path="my folder\lwjgl-2.9.1\native\windows" and it doesn't work, i've tried using
System.setProperty( "java.library.path", "my folder\\lwjgl-2.9.1\\native\\windows;"+System.getProperties().getProperty("java.library.path"));
and it doesn't work too.
I've heard that might be caused by the 64bit JVM. Do i really need to change to 32bit JVM or there is a solution?
(FYI i've searched 4 hours online before trying the good old i'm a n00b pls help me post)
It should always work when the natives are in the same folder as your jar.
If you want to put them in an other folder this solution works for me:
System.setProperty("java.library.path", path);
final Field sysPathsField = ClassLoader.class.getDeclaredField("sys_paths");
sysPathsField.setAccessible(true);
sysPathsField.set(null, null);
If you just set the "java.library.path" nothing will happen, you have to also reset the class loader. That is because the class loader caches the property internally.
I am using 64bit without problems, but that is on Linux (OpenJDK), so that can be different on windows, I don't know.
A little checklist:
- Are you really sure the path is correct?
- Have you tried specifying an absolute path?
- Have you tried to put the natives in the working directory, as Cornix suggested?
- Have you printed the java.library.path settings?
Quite obvious hints, so I don't think I'll be of any use, but just in case...
@Cornix : Thank you for your code suggestion, now it works just fine :) !
@Oebele : It's always better to check one more time with this kind of things, thank you too!
