glfw錯誤與glfwWindowHint

Question

我試過休耕this教程，它沒有奏效。我不知道它爲什麼不起作用。我正在使用Ubuntu 14.04和GNU G ++命令。

代碼：

#include <GLFW/glfw3.h> 

int main(void) { 
    glfwInit(); 
    glfwWindowHint(GLFW_CONTEXT_VERSION_MAJOR, 3); 
    glfwWindowHint(GLFW_CONTEXT_VERSION_MINOR, 2); 
    glfwWindowHint(GLFW_OPENGL_PROFILE, GLFW_OPENGL_CORE_PROFILE); 
    glfwWindowHint(GLFW_OPENGL_FORWARD_COMPAT, GL_TRUE); 

    glfwWindowHint(GLFW_RESIZABLE, GL_FALSE); 


    GLFWwindow* window = glfwCreateWindow(800, 600, "OpenGL", NULL, NULL); 

    glfwMakeContextCurrent(window); 

    while(!glfwWindowShouldClose(window)) { 
      glfwSwapBuffers(window); 
      glfwPollEvents(); 
    } 

    glfwTerminate(); 
} 

終端：

command: g++ display.cpp -lglfw -o display.out 
/tmp/cci33O9I.o: In function `main':

你不應該鏈接到glfw，但鏈接glfw3。如下所示：

g++ display.cpp -lglfw3 -o display.out
