编译报错，opengl 有进来看看么，undefined reference to

Question

问题遇到的现象和发生背景

怎么链接上这些, ubuntu 上安装了这些头文件 ， 有知道怎么编译么

问题相关代码

#include <stdio.h>
#include <stdlib.h>

#include <GL/glew.h>
#include <GLFW/glfw3.h>


int main() 
{
    glewExperimental = true;

    if (! glewInit()) {
        fprintf(stderr, "初始化 glew 失败!!");
        return -1;
    }

    glfwWindowHint(GLFW_SAMPLES, 4);
    glfwWindowHint(GLFW_CONTEXT_VERSION_MAJOR, 3);
    glfwWindowHint(GLFW_CONTEXT_VERSION_MINOR, 3);
    glfwWindowHint(GLFW_OPENGL_FORWARD_COMPAT, GL_TRUE); // To make MacOS happy; should not be needed
    glfwWindowHint(GLFW_OPENGL_PROFILE, GLFW_OPENGL_CORE_PROFILE); // We don't want the old OpenGL 

    GLFWwindow* window;

    window = glfwCreateWindow(500, 500, "window1", NULL, NULL);

    if (window == NULL) {
        fprintf(stderr, "创建 window 失败!!");
        glfwTerminate();
        return -1;
    }

    glfwMakeContextCurrent(window); // 初始化 glew
    glewExperimental = true;

    if (glewInit() != GLEW_OK) {
        fprintf(stderr, "Failed to initialize GLEW\n");
        return -1;
    }


}

这不是没装OpenGL吗
