你好，这个问题让我发疯了，我需要你的帮助。我在 IOS High Sierra v10.13.6 上，我正在尝试在没有 XCode 的 mac 上的 VSC 上尝试 OpenGL。所以我已经为正确的操作系统下载了库 GLFW。我已经尝试了GLWF website 中的基本示例。

#include "../GLFW/glfw3.h"
// g++ -v main.cpp -o main.o -L/Library/Developer/CommandLineTools/usr/include -lglfw3 -framework OpenGL
// file was built for archive which is not the architecture being linked (x86_64):
int main(void)
{
    GLFWwindow* window;

    /* Initialize the library */
    if (!glfwInit())
        return -1;

    /* Create a windowed mode window and its OpenGL context */
    window = glfwCreateWindow(640, 480, "Hello World", NULL, NULL);
    if (!window)
    {
        glfwTerminate();
        return -1;
    }

    /* Make the window's context current */
    glfwMakeContextCurrent(window);

    /* Loop until the user closes the window */
    while (!glfwWindowShouldClose(window))
    {
        /* Render here */
        glClear(GL_COLOR_BUFFER_BIT);

        /* Swap front and back buffers */
        glfwSwapBuffers(window);

        /* Poll for and process events */
        glfwPollEvents();
    }

    glfwTerminate();
    return 0;
}

我有以下目录：

当我执行这个命令时：

g++ -v main.cpp -o main.o -L/Library/Developer/CommandLineTools/usr/include -lglfw3 -framework OpenGL

我在终端出现以下错误：

Undefined symbols for architecture x86_64:

      _main in main-ca9141.o
  "_glfwInit", referenced from:

ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

我知道我来自这个警告：

ld: warning: ignoring file /Library/Developer/CommandLineTools/usr/include/libglfw3.a, file was built for archive which is not the architecture being linked (x86_64): /Library/Developer/CommandLineTools/usr/include/libglfw3.a

我用 lipo 命令检查了库，它说他的架构是 x86_64！我不知道为什么它不起作用，你能帮帮我吗？

提前致谢。

【解决方案1】：

我想说我找到了解决问题的方法。您必须仔细检查库 libglfw3.a 是在 x86_64 的良好架构中编译的。

在这里官方link 下载正确操作系统中的 GLFW 库

这里是编译所需的命令：

你需要确保通过-L指定库的路径

g++ main.cpp -o main -L/Library/Developer/CommandLineTools/usr/include -lglfw3 -framework Cocoa -framework OpenGL -framework IOKit

希望它对陷入同样问题的未来开发者有所帮助
