LWJGL：打开窗口导致程序崩溃

我正在尝试在Java/LWJGL中制作一个简单的游戏。我正在关注一个在Windows上制作的教程，并且我正在使用一个mac。我复制了他的代码以打开角色的窗口角色，并且程序立即崩溃，给我一个很长很奇怪的错误，可能与指针有关（我实际上不知道）。下面是用于创建我用一个窗口，宽度和高度的属性定义行：LWJGL：打开窗口导致程序崩溃

window = glfwCreateWindow(width, height, "Flappy Bird", NULL, NULL);

当我在我的Mac上运行它，它给了我这个错误：

libc++abi.dylib: terminating with uncaught exception of type NSException

一窗口也弹出，说：“java在使用libglfw.dylib插件时意外退出。”

我安装了LWJGL错误还是我的代码有瑕疵？谢谢您的帮助！

你不应该忽略所有的例外。抛出一个异常或打印一条消息，无论你现在只是返回。您还应该使用[glfwSetErrorCallback]（http://javadoc.lwjgl.org/org/lwjgl/glfw/GLFW.html#glfwSetErrorCallback（org.lwjgl.glfw.GLFWErrorCallback））设置错误回调，并使用' - Dorg.lwjgl.util.Debug = TRUE;。 – javac

如果您使用的是LWJGL 3我建议您按照Oskar的视频教程来设置您的项目和显示。

Workspace setting

Display tutorial

并尝试在你的glfwCreateWindow通话使用MemoryUtil.NULL而不是标准null。

'MemoryUtil.NULL'很长，'null'是一个对象，所以你不能“改用它”。 – javac
