Exception in Thread "Main" Java.Lang.Unsatisfiedlinkerror: No Lwjgl in Java.Library.Path

Getting 'java.lang.UnsatisfiedLinkError': no lwjgl in java.library.path

You don't have the natives set up in your LWJGL application.

Here's how to do it:

1. Go to your LWJGL folder that contains the folders named "jar", "res", "doc", and "native". You need to go into Eclipse (assuming you use eclipse), open your project in the Project Explorer on the left side of your screen.
2. Right click on the "JRE System Library" of your project, and click "Build Path" -> "Configure Build Path".
3. Include the LWJGL native libraries to your project in the Build Path Configurer by clicking the "Native library location" which can be seen in the JRE System Library dropdown menu.
4. Click on "Edit...", which will be the only button clickable in that general area.
5. A file explorer will pop up. Navigate to the location of your LWJGL native folder (The location should be something like "C:\Users\YOURUSERNAMEHERE\Desktop\Java\eclipse\lwjgl-2.9.0\native" if you are using Windows) and include the folder named [Your OS here].

Hope this helped :)

LWJGL 'java.lang.UnsatisfiedLinkError': no lwjgl in java.library.path

LWJGL uses its own variables for the path to the native libraries:

 System.setProperty("org.lwjgl.librarypath", new File("pathToNatives").getAbsolutePath());

If you kept the file structure from the LWJGL package you can use something like this:

    switch(LWJGLUtil.getPlatform())
    {
        case LWJGLUtil.PLATFORM_WINDOWS:
        {
            JGLLib = new File("./native/windows/");
        }
        break;

        case LWJGLUtil.PLATFORM_LINUX:
        {
            JGLLib = new File("./native/linux/");
        }
        break;

        case LWJGLUtil.PLATFORM_MACOSX:
        {
            JGLLib = new File("./native/macosx/");
        }
        break;
    }

    System.setProperty("org.lwjgl.librarypath", JGLLib.getAbsolutePath());

Exception in thread main java.lang.UnsatisfiedLinkError: no lwjgl-devil in java.library.path

You need the lwjgl-devil.dll and the DevIL.dll which you get here
http://openil.sourceforge.net/download.php

When I run the .jar, I get a No lwjgl in java.library.path error

you have to point the jvm to where the native files are located using a command line parameter -Djava.library.path="path/to/natives". You could use a batch (.bat) file to specify this and start your application for you.

Alternatively you can use a tool like JarSplice to create a single executable jar file from all your jars and at the same time include your native files inside it. It automates the tricky part of specifying the natives manually and provides a nicer end user experience.

To use JarSplice just select your game.jar, lwjgl.jar, lwjgl_util.jar, and jinput.jar in the jars tab. Then all the *.dll, *.so, *.dylib and *.jnilib files in the natives tab. Add your main class on the class tab and create the single executable jar.

java.lang.UnsatisfiedLinkError: no lwjgl in java.library.path but natives are set

It turns out that my anti-virus is deleting LWJGL.

no lwjgl in java.library.path - however as far as I can see, everything is linked correctly

When your program cant find the a library when exported from eclipse it is typically because you either forget to bundle the lwjgl files along with your app (.dll & .so native files), or it was not linked correctly.

See here for your exact issue: Can't start .jar file (using LWJGL)

You probably forgot to use -Djava.library.path=path/to/dir

And you can find a more generic info here:
