xCode 8.1 GLFWWindow "first responder" 问题

Question

我最近一直在使用 OpenGL，并决定将 C++ 用于我最新的 OpenGL 项目。我正在使用 xCode 8.1，我的库路径和 header 路径正确链接。一切编译正常，但我在运行时收到此错误：

2016-11-03 15:17:24.649264 Modulo[25303:14858638] [General] ERROR: Setting <GLFWContentView: 0x100343da0> as the first responder for window <GLFWWindow: 0x100222540>, but it is in a different window ((null))! This would eventually crash when the view is freed. The first responder will be set to nil.(

我运行产生这个错误的代码如下：

#include <iostream>
#define GLEW_STATIC
#include <GL/glew.h>
#include <GLFW/glfw3.h>

int main(int argc, const char * argv[]) {
    //Engine Startup.
    std::cout << "<----- Engine Start-Up ----->" << std::endl;
    //Initialize GLFW.
    if(!glfwInit()) {
        std::cout << "- GLFW Failed to Initialize!" << std::endl;
        return -1;
    }
    std::cout << "+ GLFW Initialized!" << std::endl;
    //Create GLFWWindow
    GLFWwindow* window = glfwCreateWindow(640, 480, "Engine", nullptr, nullptr);
    if(!window) {
        std::cout << "- GLFWWindow Failed to Create!" << std::endl;
        glfwTerminate();
        return -1;
    }
    std::cout << "+ GLFWWindow Created!" << std::endl;
    return 0;
}

程序正常运行，但此错误可能会在以后成为问题，并且还会使控制台难以调试，所以我想尽早尝试解决它！

在此先感谢您，如果需要更多信息，请告诉我！ :)

Answer 1

我是初学者，也遇到过这个问题

我遇到错误但成功创建 window。如何添加：

glfwWindowHint(GLFW_CONTEXT_VERSION_MAJOR, 3);
glfwWindowHint(GLFW_CONTEXT_VERSION_MINOR, 2);
glfwWindowHint(GLFW_OPENGL_FORWARD_COMPAT, GL_TRUE);
glfwWindowHint(GLFW_OPENGL_PROFILE, GLFW_OPENGL_CORE_PROFILE);

在 glfwCreateWindow 之前?

Answer 2

注意此处的讨论，这表明它是 macOS Sierra 中的一个已知错误，已在 GLFW 的 git 存储库中解决，但尚未发布。
