Lwjgl Javadoc Download !EXCLUSIVE!
Irmela Adalja
You are trying to compile LWJGL 2 code here. All the imports that it cannot find pertain to the verison 2 of LWJGL. The current version that you can get from the mentioned lwjgl site is 3 and version 3 is incompatible with version 2.
(Optional) Create a LWJGL binary directory, says "lwjgl-2.9.1" - I shall denote the binary directory as $LWJGL_HOME. Create sub-directories "jar", "lib", "src", "javadoc" under the $LWJGL_HOME.Copy the necessary jar-file, native libraries of your operating platform, and source-files into the appropriate sub-directories.For example, for Win32, copy all the jar-file into "jar"; the 32-bit libraries at "native\windows" into "lib"; and "lwjgl-source-2.9.1.zip" into "src" (no need to unzip). Unzip the javadocs downloaded into "javadoc".
Native Libraries: Native libraries refer to the JNI binaries (in the form of ".dll" (for Windows) or ".so" for Linux) in the JOGL's "lib" directory, e.g., "lwjgl.dll". These dll's are needed for proper operations.
Error in Native Libraries: If you receive an error message "SEVERE: java.lang.UnsatisfiedLinkError: no xxx in java.library.path", print out the entries in java.library.path via the following statement and check if $LWJGL_HOME\lib (which contains "lwjgl.dll") are included in one of the paths. "java.library.path" is supposed to mirror the PATH environment variable.
It seems that this method (nSetClassHint) was added in LWJGL version 2.9.1
The error could be explained if the version of LWJGL java sources in JME is >=2.9.1, while they bundled a liblwjgl64.so of version < 2.9.1. Is there a way to verify this ?
Looks like you either have lwjgl in a global java library directory and its falsely used or you somehow combined your own libraries instead of using the default SDK project and the supplied lwjgl libraries.
if the natives and the jar does not match lwjgl does a version mismatch error. Except its a very old lwjgl version that gets pulled from somewhere.
