Description

I am using Netbeans to build an LWJGL project. The program runs fine on Mac, but when I try to run it on Windows (java -Dorg.lwjgl.util.Debug=true -Dorg.lwjgl.util.DebugLoader=true -jar RevuePlayer2.jar), I get this error:

[LWJGL]         lwjgl.dll not found in java.library.path
[LWJGL] Failed to load a library. Possible solutions:
        a) Add the directory that contains the shared library to -Djava.library.path or -Dorg.lwjgl.librarypath.
        b) Add the JAR that contains the shared library to the classpath.
Exception in thread "main" java.lang.UnsatisfiedLinkError: Failed to locate library: lwjgl.dll

As far as I can see, the right natives jars are included:

Teotihuacan:dist millerti$ ls
README.TXT       RevuePlayer2.jar lib
Teotihuacan:dist millerti$ ls lib/
RevueMedia2.jar                  lwjgl-glfw-natives-windows.jar   lwjgl-natives-macos.jar          lwjgl-opengl-natives-macos.jar   lwjgl-opengl.jar                 revue_lib-1.0-SNAPSHOT.jar
lwjgl-glfw-natives-macos.jar     lwjgl-glfw.jar                   lwjgl-natives-windows.jar        lwjgl-opengl-natives-windows.jar lwjgl.jar

Being a netbeans project, the manifest is what specifies the classpath, and here are the contents of META-INF/MANIFEST.MF:

Manifest-Version: 1.0
Ant-Version: Apache Ant 1.10.4

X-COMMENT: Main-Class will be added automatically by build

Turns out among the various things that my sysadmin did to mess up my PC was to remove the paths to newer Java releases. As a result, I was running a 32-bit java 8. My recommendation here would be to have the error message be explicit about the fact that there is a mismatch between the architecture of the JVM and that of the DLLs in the jars.

Hey @theosib, thanks for the suggestion!

Starting from the next snapshot, LWJGL will try to detect platform/architecture mismatches and will print something like this when it can't resolve a native library:

[LWJGL] Platform/architecture mismatch detected for module: org.lwjgl.opengl
