foo*_*oop 5 c++ opengl glfw visual-studio-2015
我遇到一个问题,其中以下几行代码始终显示“ Failed to initialize初始化glad”,然后退出程序:
if (!gladLoadGLLoader((GLADloadproc)glfwGetProcAddress))
{
std::cout << "Failed to initialize GLAD" << std::endl;
return -1;
}

我一直在使用https://learnopengl.com/作为指南,并一直遵循入门部分中的步骤。我正在使用Visual Studio编写此文件,已将glad.c源文件移至内部版本以使其正常工作,并将头文件添加到我指定的glfw头文件所在的位置,但我一直无法找到任何与我有类似问题的人。
评论返回-1;该行会导致访问冲突异常,因此肯定是程序有问题。
这是整个程序,以防万一我想念其他东西:
#include "stdafx.h"
#include <GLFW/glfw3.h>
#include <glad/glad.h>
#include <iostream>
using namespace std;
void init_glfw();
void framebuffer_size_callback(GLFWwindow*, int, int);
int main(int argc, char **argv)
{
init_glfw();
GLFWwindow* window = glfwCreateWindow(800, 600, "Lab3", NULL, NULL);
if (window == NULL)
{
cout << "Failed to create GLFW window" << endl;
glfwTerminate();
return -1;
}
if (!gladLoadGLLoader((GLADloadproc)glfwGetProcAddress))
{
std::cout << "Failed to initialize GLAD" << std::endl;
return -1;
}
glViewport(0, 0, 800, 600);
glfwSetFramebufferSizeCallback(window, framebuffer_size_callback);
while (!glfwWindowShouldClose(window))
{
glfwSwapBuffers(window);
glfwPollEvents();
}
glfwTerminate();
return 0;
}
void init_glfw()
{
glfwInit();
glfwWindowHint(GLFW_CONTEXT_VERSION_MAJOR, 3);
glfwWindowHint(GLFW_CONTEXT_VERSION_MINOR, 3);
glfwWindowHint(GLFW_OPENGL_PROFILE, GLFW_OPENGL_CORE_PROFILE);
}
void framebuffer_size_callback(GLFWwindow* window, int width, int height)
{
glViewport(0, 0, width, height);
}

您从未通过来使GL上下文成为当前上下文glfwMakeContextCurrent()。与其他GL窗口框架不同,glfwCreateWindow()成功时GLFW不会使GL上下文保持最新。
成功glfwMakeContextCurrent()后调用glfwCreateWindow():
GLFWwindow* window = glfwCreateWindow(800, 600, "Lab3", NULL, NULL);
glfwMakeContextCurrent( window );
if (window == NULL)
{
cout << "Failed to create GLFW window" << endl;
glfwTerminate();
return -1;
}
if (!gladLoadGLLoader((GLADloadproc)glfwGetProcAddress))
{
std::cout << "Failed to initialize GLAD" << std::endl;
return -1;
}
