Question

当我启动程序时，会打开一个空控制台而不是黑屏。错误发生在创建窗口“window = glfwCreateWindow(640, 480, "Hello World", NULL, NULL);”。代码取自 glfw 文档，没有错误。

glfw 使用命令“git clone https://github.com/glfw/glfw.git external/glfw/”安装

main.cpp

#include <GLFW/glfw3.h>

int main(void)
{
    GLFWwindow* window;
    if (!glfwInit())
        return -1;
    window = glfwCreateWindow(640, 480, "Hello World", NULL, NULL);
        if (!window)
        {
            glfwTerminate();
            return -1;
        }
        glfwMakeContextCurrent(window);
        while (!glfwWindowShouldClose(window))
        {
            //glClear(GL_COLOR_BUFFER_BIT);
            glfwSwapBuffers(window);
            glfwPollEvents();
        }
        glfwTerminate();
        return 0;
    }
