在Mac OS X上加载JNI lib？ [英] Loading JNI lib on Mac OS X?

问题描述

背景

所以我试图加载一个jnilib（特别是 JOGL ）在运行时在Mac OS X上运行到Java。我一直关注相关的Stack Overflow问题：

So I am attempting to load a jnilib (specifically JOGL) into Java on Mac OS X at runtime. I have been following along the relevant Stack Overflow questions:

• Maven和JOGL库


• 在Java中加载DLL - Eclipse - JNI


• 如何制作包含所有jar文件的jar文件

• Maven and the JOGL Library
• Loading DLL in Java - Eclipse - JNI
• How to make a jar file that include all jar files

我的最终目标是将特定于平台的JOGL文件打包到JAR中并将它们解压缩到临时目录中并在启动时加载它们。我回过头来尝试使用硬编码路径加载JOGL：

The end goal for me is to package platform specific JOGL files into a JAR and unzip them into a temp directory and load them at start-up. I worked my problem back to simply attempting to load JOGL using hard-coded paths:

    File f = new File("/var/folders/+n/+nfb8NHsHiSpEh6AHMCyvE+++TI/-Tmp-/libjogl.jnilib");
    System.load(f.toString());
    f = new File ("/var/folders/+n/+nfb8NHsHiSpEh6AHMCyvE+++TI/-Tmp-/libjogl_awt.jnilib");
    System.load(f.toString());

尝试使用JOGL API时出现以下异常：

I get the following exception when attempting to use the JOGL API:

    Exception in thread "main" java.lang.UnsatisfiedLinkError: no jogl in java.library.path

但是当我通过添加以下JVM选项指定 java.library.path 时：

But when I specify java.library.path by adding the following JVM option:

    -Djava.library.path="/var/folders/+n/+nfb8NHsHiSpEh6AHMCyvE+++TI/-Tmp-/" 

一切正常。

问题

是否可以使用 System.load （或在Mac OS X上作为-Djava.library.path的替代品在运行时被调用？

Is it possible use System.load (or some other variant) on Mac OS X as a replacement for -Djava.library.path that is invoked at runtime?

推荐答案

Jogl总是尝试自动加载所有依赖库。
为避免这种情况，应该有一个NativeLibLoader类，您可以在通过System.load（）

Jogl always tries to auto-load all dependent libraries. To avoid this, there should be a NativeLibLoader class where you can call disableLoading() before you load the libraries yourself via the System.load()
