c++ - glfw在Visual Studio 2017上打开后立即关闭

此测试代码使opengl窗口打开并在出现后立即消失。是的，我正在从源代码编译库。

我的代码有什么问题？

#include<glad\glad.h>
#include<GLFW\glfw3.h>
#include<stdio.h>
#include<stdlib.h>

int main()
{
if (glfwInit() == false)
{
    fprintf(stderr, "GLFW Failed to initialise");
    return -1;
}
glfwWindowHint(GLFW_SAMPLES, 4);
glfwWindowHint(GLFW_CONTEXT_VERSION_MAJOR, 4);
glfwWindowHint(GLFW_CONTEXT_VERSION_MINOR, 5);
glfwWindowHint(GLFW_OPENGL_PROFILE, GLFW_OPENGL_CORE_PROFILE);

GLFWwindow * window = glfwCreateWindow(640, 480, "Test OPENGL", NULL, NULL);
if (!window)
{
    fprintf(stderr, "window failed to open");
    glfwTerminate();
    return -1;
}

glfwMakeContextCurrent(window);
//system("pause");
if (!gladLoadGLLoader((GLADloadproc)glfwGetProcAddress))
{
    fprintf(stderr, "Failed to initialize GLAD");
    return -1;
}
return 0;
}

最佳答案

You need an event loop to pump the message queue and swap buffers:

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

    // draw stuff

    glfwSwapBuffers(window);
}
