使用GLFW和GLAD制作C ++程序OpenGL时遇到这些错误

如何解决使用GLFW和GLAD制作C ++程序OpenGL时遇到这些错误

尝试遵循本教程时（我第一次制作OpenGL程序），我得到这些错误。 有人知道为什么会发生吗？我知道链接器在链接时遇到麻烦，但是我不知道为什么。还有优化/改进代码以及改善问题的技巧吗？我对stackoverflow很不好笑
编辑1：我现在知道链接器缺少共享库，但是我没有要链接的链接/我的图书馆GLAD / GLFW中没有链接的链接。
编辑2：经过更多研究，事实证明某些事情可能没有正确定义。但是这些错误来自GLAD / GLFW，而不是我的代码。有什么帮助吗？ （Source）

代码：

#include <glad/glad.h>
#include <GLFW/glfw3.h>

#include <iostream>

void framebuffer_size_callback(GLFWwindow* window,int width,int height);
void processInput(GLFWwindow *window);

// settings
const unsigned int SCR_WIDTH = 854;
const unsigned int SCR_HEIGHT = 480;

int main()
{
    // glfw: initialize and configure
    // ------------------------------
    glfwInit();
    glfwWindowHint(GLFW_CONTEXT_VERSION_MAJOR,3);
    glfwWindowHint(GLFW_CONTEXT_VERSION_MInor,3);
    glfwWindowHint(GLFW_OPENGL_PROFILE,GLFW_OPENGL_CORE_PROFILE);

#ifdef __APPLE__
    glfwWindowHint(GLFW_OPENGL_FORWARD_COMPAT,GL_TRUE);
#endif

    // glfw window creation
    // --------------------
    GLFWwindow* window = glfwCreateWindow(SCR_WIDTH,SCR_HEIGHT,"epic new window",NULL,NULL);
    if (window == NULL)
    {
        std::cout << "Failed to create GLFW window" << std::endl;
        glfwTerminate();
        return -1;
    }
    glfwMakeContextCurrent(window);
    glfwSetFramebufferSizeCallback(window,framebuffer_size_callback);

    // glad: load all OpenGL function pointers
    // ---------------------------------------
    if (!gladLoadGLLoader((GLADloadproc)glfwGetProcAddress))
    {
        std::cout << "Failed to initialize GLAD" << std::endl;
        return -1;
    }    

    // render loop
    // -----------
    while (!glfwWindowShouldClose(window))
    {
        // input
        // -----
        processInput(window);

        // render
        // ------
        glClearColor(0.0f,0.0f,0.3f,1.0f);
        glClear(GL_COLOR_BUFFER_BIT);

        // glfw: swap buffers and poll IO events (keys pressed/released,mouse moved etc.)
        // -------------------------------------------------------------------------------
        glfwSwapBuffers(window);
        glfwPollEvents();
    }

    // glfw: terminate,clearing all prevIoUsly allocated GLFW resources.
    // ------------------------------------------------------------------
    glfwTerminate();
    return 0;
}

// process all input: query GLFW whether relevant keys are pressed/released this frame and react accordingly
// ---------------------------------------------------------------------------------------------------------
void processInput(GLFWwindow *window)
{
    if(glfwGetKey(window,GLFW_KEY_ESCAPE) == GLFW_PRESS)
        glfwSetwindowShouldClose(window,true);
}

// glfw: whenever the window size changed (by OS or user resize) this callback function executes
// ---------------------------------------------------------------------------------------------
void framebuffer_size_callback(GLFWwindow* window,int height)
{
    // make sure the viewport matches the new window dimensions; note that width and 
    // height will be significantly larger than specified on retina displays.
    glViewport(0,width,height);
}
