很高兴未能初始化
Glad failing to initialize
我遇到以下代码行总是打印 "Failed to initialize glad" 然后退出程序的问题:
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,并一直按照入门部分中的步骤进行操作。我正在使用 Visual Studio 编写此代码,我已将 glad.c 源文件移动到构建中以使其正常工作,并将 header 文件添加到我指定 glfw [=24] 的相同位置=] 会,但我没能找到任何人遇到与我类似的问题。
注释掉return-1;行导致访问冲突异常,所以肯定是程序有问题。
这是整个程序,以防我遗漏了其他内容:
#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 glfwMakeContextCurrent()
使您的 GL 上下文成为当前上下文。与其他 GL 窗口框架不同,当 glfwCreateWindow()
成功时,GLFW 不会使 GL 上下文保持当前状态。
Call glfwMakeContextCurrent()
after glfwCreateWindow()
succeeds:
GLFWwindow* window = glfwCreateWindow(800, 600, "Lab3", NULL, NULL);
if (window == NULL)
{
cout << "Failed to create GLFW window" << endl;
glfwTerminate();
return -1;
}
glfwMakeContextCurrent( window );
if (!gladLoadGLLoader((GLADloadproc)glfwGetProcAddress))
{
std::cout << "Failed to initialize GLAD" << std::endl;
return -1;
