LWJGL

Question

我正在尝试在 macOS Big Sur 11.6（Apple M1 芯片）上运行来自 https://www.lwjgl.org/guide 的示例代码。我导入了所有必要的库并在 VM 选项中写入 -XstartOnFirstThread 并收到此错误：

[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.
[LWJGL] Enable debug mode with -Dorg.lwjgl.util.Debug=true for better diagnostics.
[LWJGL] Enable the SharedLibraryLoader debug mode with -Dorg.lwjgl.util.DebugLoader=true for better diagnostics.
Exception in thread "main" java.lang.UnsatisfiedLinkError: Failed to locate library: liblwjgl.dylib
    at org.lwjgl.system.Library.loadSystem(Library.java:162)

    at com.company.HelloWorld.init(HelloWorld.java:38)
    at com.company.HelloWorld.run(HelloWorld.java:23)
    at com.company.HelloWorld.main(HelloWorld.java:113)

我已经尝试将 natives 从其他 jar 文件手动提取到项目文件夹中单独的“native/”文件夹，并将 -Dorg.lwjgl.librarypath=native 作为 VM 选项传递，但它完全没有改变。我不知道是否应该将“native/”文件夹添加到库中，但它似乎对结果也没有影响。

这是来自 LWJGL 网站的示例代码：

        // OpenGL context, or any context that is managed externally.
        // LWJGL detects the context that is current in the current thread,
        // creates the GLCapabilities instance and makes the OpenGL
        // bindings available for use.
        GL.createCapabilities();

        // Set the clear color
        glClearColor(1.0f, 0.0f, 0.0f, 0.0f);

Answer 1

您 select 在 LWJGL 定制器中为您的 CPU 架构输入了错误的本机。您 selected macOS x64，但是 M1 不是 x86，而是 arm。当前* LWJGL 版本 3.2.3 不支持 macOS arm。您必须在 LWJGL 定制器上使用 3.3.0 抢先体验版，然后 select macOS arm64 本机。

编辑：

* LWJGL 3.3.0 已经发布，因此不必再选择“抢先体验”版本。 x64 和 arm natives 现在都可以 select 在 LWJGL 的稳定版本中编辑。
