glfwWindowHint（）调用后，GLFW窗口创建失败

Question

我正在尝试使用GLFW3创建一个窗口。当我在我的桌面上做这件事时，效果很好。在我的笔记本电脑上，它无法创建窗口，程序崩溃。删除glfwWindowHint（）调用可以防止崩溃，但我的代码无法工作，因为我使用了错误的openGL版本。以下是窗口代码：

Window::Window(int width, int height, std::string title, bool full)
{
    glfwInit();
    glfwWindowHint(GLFW_OPENGL_FORWARD_COMPAT, GL_TRUE);
    glfwWindowHint(GLFW_CONTEXT_VERSION_MAJOR, 4);
    glfwWindowHint(GLFW_CONTEXT_VERSION_MINOR, 1);
    glfwWindowHint(GLFW_OPENGL_PROFILE, GLFW_OPENGL_CORE_PROFILE);
    glfwWindowHint(GLFW_RESIZABLE, GL_FALSE);

    m_width = width;
    m_height = height;
    if (full)
    {
        m_window = glfwCreateWindow(width, height, title.c_str(), glfwGetPrimaryMonitor(), nullptr);
    }
    else
    {
        m_window = glfwCreateWindow(width, height, title.c_str(), nullptr, nullptr);
    }
    glfwMakeContextCurrent(m_window);

    glewExperimental = GL_TRUE;
    glewInit();
    glEnable(GL_DEPTH_TEST);
    glViewport(0, 0, width, height);

}

这可能与我的台式机有NVidia图形，而我的笔记本电脑有集成图形有关吗？

更新：它在调用glfwSwapBuffers（）时崩溃，我将glfw错误65543打印到控制台。glfwCreateWindow（）返回NULL；

Answer 1

如果它将错误65543打印到控制台，则相当于glfw3中定义的0x00010007。h作为GLFW_版本不可用。
