LWJGL-在IntelliJ IDEA中找不到库：liblwjgl.dylib

问题描述

我尝试在MacOS Big Sur 11.6(Apple M1芯片)上运行https://www.lwjgl.org/guide中的示例代码。我导入了所有必需的库，并在VM选项中写入-XstartOnFirstThread，得到以下错误：

[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 org.lwjgl.system.Library.loadSystem(Library.java:62)

    at org.lwjgl.system.MemoryUtil.<clinit>(MemoryUtil.java:97)

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

我尝试手动将其他JAR中的本机文件提取到项目文件夹中的一个单独的"；ative/"；文件夹中，并将-Dorg.lwjgl.librarypath=native作为一个VM选项传递，但它完全没有任何改变。我不知道是否应该将"；ative/"；文件夹添加到库中，但它似乎也不会影响结果。

以下是来自LWJGL网站的示例代码：

        glfwTerminate();
        glfwSetErrorCallback(null).free();
    }

    private void init() {

        // will print the error message in System.err.

            // Get the window size passed to glfwCreateWindow
            glfwGetWindowSize(window, pWidth, pHeight);

            // Get the resolution of the primary monitor

        glfwSwapInterval(1);

        // Make the window visible
        glfwShowWindow(window);
    }

    private void loop() {
        // This line is critical for LWJGL's interoperation with GLFW's
        // 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);

        // Run the rendering loop until the user has attempted to close
        // the window or has pressed the ESCAPE key.
        while ( !glfwWindowShouldClose(window) ) {
            glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT); // clear the framebuffer

            glfwSwapBuffers(window); // swap the color buffers

            // Poll for window events. The key callback above will only be
            // invoked during this call.
            glfwPollEvents();
        }
    }

    public static void main(String[] args) {
        new HelloWorld().run();
    }

}

推荐答案

您在LWJGL定制器中为您的CPU体系结构选择了错误的本机代码。您选择了MacOS x64，但是M1不是x86，而是ARM。当前的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早期访问版本，然后选择MacOS arm64本机。
