Package native libraries
Native libraries should be packaged into a single jar file, with the following directory & file structure:
/natives
/linux_32
libxxx[-vvv].so
/linux_64
libxxx[-vvv].so
/osx_32
libxxx[-vvv].dylib
/osx_64
libxxx[-vvv].dylib
/osx_arm64
libxxx[-vvv].dylib
/windows_32
xxx[-vvv].dll
/windows_64
xxx[-vvv].dll
/aix_32
libxxx[-vvv].so
libxxx[-vvv].a
/aix_64
libxxx[-vvv].so
libxxx[-vvv].a
Here "xxx" is the name of the native library and "-vvv" is an optional version number. Depending on the platform at runtime, a native library will be unpacked into a temporary file and will be loaded from there.
The version information will be grabbed from the MANIFEST.mf file from "Implementation-Version" entry. So it's recommended to follow Java's package version information convention.
Load library
If you want to load 'awesome.dll' (on Windows) or 'libawesome.so' (on Linux or AIX), simply do like this ...
NativeLoader.loadLibrary("awesome");
