OpenGL,GLFW,很高兴。glViewport(0,0,800600)引发内存错误[关闭]

我最近开始关注 these OpenGL教程。我一直没有遇到麻烦,直到 你好窗口 gladLoadGLLoader((GLADloadproc)glfwGetProcAddress) 返回false。这会导致以下错误:

Exception thrown at 0x00000000 in openGL_001.exe: 0xC0000005: Access violation executing location 0x00000000.

和

Unhandled exception at 0x7281C1ED in openGL_001.exe: 0xC0000005: Access violation executing location 0x00000000.

glViewport(0, 0, 800, 600) 很高兴 已成功处理OpenGL的函数指针。我尝试使用以下方法使其工作 很高兴 configurations

语言:C/C++,规格:OpenGl

• API gl:v.3.3,剖面:核心

代码:

#include <iostream>
#include <glad\glad.h>
#include <GLFW\glfw3.h>

void framebuffer_size_callback(GLFWwindow* window, int width, int height);

int main() {
glfwInit();
glfwWindowHint(GLFW_CONTEXT_VERSION_MAJOR, 3);
glfwWindowHint(GLFW_CONTEXT_VERSION_MINOR, 3);
glfwWindowHint(GLFW_OPENGL_PROFILE, GLFW_OPENGL_CORE_PROFILE);

GLFWwindow* window = glfwCreateWindow(800, 600, "Learn OpenGL", NULL, NULL);
if (window = NULL) {
    std::cout << "Failed to create GLFW window" << std::endl;
    glfwTerminate();
    return -1;
}
glfwMakeContextCurrent(window);

if (!gladLoadGLLoader((GLADloadproc)glfwGetProcAddress)) {
    std::cout << "Failed to initialise GLAD" << std::endl;
}

glViewport(0, 0, 800, 600);
glfwSetFramebufferSizeCallback(window, framebuffer_size_callback);

//render loop
while (!glfwWindowShouldClose(window)) {
    glfwSwapBuffers(window);
    glfwPollEvents();
}
glfwTerminate();
return 0;

}

void framebuffer_size_callback(GLFWwindow* window, int width, int height) {
glViewport(0, 0, width, height);
