glfwCreateWindow返回NULL问题

Posted 2021-06-08 今天也要努力搬砖

opengl学习中遇到glfwCreateWindow返回空问题

代码如下

        int ret=glfwInit();
	glfwWindowHint(GLFW_CONTEXT_VERSION_MAJOR, 3);
	glfwWindowHint(GLEW_VERSION_MINOR, 3);
	glfwWindowHint(GLFW_OPENGL_PROFILE, GLFW_OPENGL_CORE_PROFILE);
	
	GLFWwindow* window = glfwCreateWindow(800, 600, "Test window", NULL, NULL);
	if (window == NULL)
	{
		std::cout << "open window failed." << std::endl;
		glfwTerminate();
		return EXIT_FAILURE;
	}
	glfwMakeContextCurrent(window);

解决方案： 1、查看本电脑opengl版本

下载并安装OpenGL Extensions Viewer后可以查看本电脑OpenGL版本

2、代码中OpenGL版本改成与本电脑一致

//glfwWindowHint(GLFW_CONTEXT_VERSION_MAJOR, 3);
//glfwWindowHint(GLEW_VERSION_MINOR, 3);
glfwWindowHint(GLFW_CONTEXT_VERSION_MAJOR, 4);
glfwWindowHint(GLEW_VERSION_MINOR, 3);
