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，我的库路径和标题路径正确链接。一切都编译好但我在运行时遇到这个错误：

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.(

我运行以生成此错误的代码如下：

#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;
}

该程序按预期执行，但此错误可能会在以后成为一个问题，也会使控制台难以调试，所以我想尽早解决它！

我是初学者，我也遇到过这个问题。

我收到错误但成功创建了窗口。如何添加：

public void showDialog() {

        dialog = new Dialog(MainActivity.this);
        dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
        dialog.getWindow().setBackgroundDrawable(
                new ColorDrawable(android.graphics.Color.TRANSPARENT));
        dialog.setContentView(R.layout.dialog_layout);
        dialog.setCanceledOnTouchOutside(false);
        dialog.setCancelable(true);

        btn_snooze = (Button) dialog.findViewById(R.id.btn_snooze);

        btn_snooze.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                dialog.cancel();
            }
        });

        dialog.show();
    }

之前的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);？

请注意这里的讨论GLFW first responder error，这表明它是macOS Sierra中的已知错误，已在GLFW的git repo中解决，但尚未发布。
