Question

我正在尝试使用g ++从glfw页面编译示例程序。

#include <GLFW/glfw3.h>

int main(void)
{
    GLFWwindow* window;

    /* Initialize the library */
    if (!glfwInit())
        return -1;

    /* Create a windowed mode window and its OpenGL context */
    window = glfwCreateWindow(640, 480, "Hello World", NULL, NULL);
    if (!window)
    {
        glfwTerminate();
        return -1;
    }

    /* Make the window's context current */
    glfwMakeContextCurrent(window);

    /* Loop until the user closes the window */
    while (!glfwWindowShouldClose(window))
    {
        /* Render here */
        glClear(GL_COLOR_BUFFER_BIT);

        /* Swap front and back buffers */
        glfwSwapBuffers(window);

        /* Poll for and process events */
        glfwPollEvents();
    }

    glfwTerminate();
    return 0;
}

问题是我得到了对glfw函数的未定义引用。 g ++命令：

g++ -IGLFW/include -c sample.cpp

g++ -o sample.exe -LGLFW/lib-mingw-w64 sample.o libglfw3.a

错误消息：

我已经检查了多个来源，看看我是否链接错误，但对我来说一切看起来都正确。

我的操作系统是Windows 10

g ++不与GLFW链接
