Question

glfwOpenWindowHint在此作用域中未声明 GLFW3和GLEW

开始学习OpenGL 3+时，我遵循了一些OpenGL教程。但是，我遇到了一些不一致的问题。这里是我设法得到的代码，但是我刚开始就遇到了大量的错误，没有一个错误提示说找不到包含的头文件，而是说这些头文件没有定义核心函数。

#include <stdio.h>
#include <stdlib.h>
#include <GL/glew.h>
#include <GL/glfw3.h>
#include <glm/glm.hpp>

int main(){

// Initialise GLFW
if( !glfwInit() )
{
    fprintf( stderr, "Failed to initialize GLFW\n" );
    return -1;
}

glfwOpenWindowHint(GLFW_FSAA_SAMPLES, 4); // 4x antialiasing
glfwOpenWindowHint(GLFW_OPENGL_VERSION_MAJOR, 3);
glfwOpenWindowHint(GLFW_OPENGL_VERSION_MINOR, 3);
glfwOpenWindowHint(GLFW_OPENGL_PROFILE, GLFW_OPENGL_CORE_PROFILE); //I don't want the
                                                                   //old OpenGL

// Open a window and create its OpenGL context
if( !glfwOpenWindow( 1024, 768, 0,0,0,0, 32,0, GLFW_WINDOW ) )
{
    fprintf( stderr, "Failed to open GLFW window\n" );
    glfwTerminate();
    return -1;
}

// Initialize GLEW
glewExperimental=true; // Needed in core profile
if (glewInit() != GLEW_OK) {
    fprintf(stderr, "Failed to initialize GLEW\n");
    return -1;
}

glfwSetWindowTitle( "Tutorial 01" );

// Ensure we can capture the escape key being pressed below
glfwEnable( GLFW_STICKY_KEYS );

do{
    // Draw nothing

    // Swap buffers
    glfwSwapBuffers();

} // Check if the ESC key was pressed or the window was closed
while( glfwGetKey( GLFW_KEY_ESC ) != GLFW_PRESS &&
glfwGetWindowParam( GLFW_OPENED ) );

问题在于MinGW不太喜欢这个，导致产生了大量的"未声明"错误，而所有这些错误都是OpenGL窗口存在所必需的。我从未使用过除一点SDL2之外的任何图形库，因此您可能需要引导我完成这个过程...非常感谢。

您正在使用GLFW3的头文件，但您编写的代码是针对GLFW2的。

在GLFW3中，函数glfwOpenWindowHint()被重命名为glfwWindowHint()。

请查看此页面以获取升级说明：http://www.glfw.org/docs/3.0/moving.html 自GLFW2以来发生了很多变化。
