Question

当我尝试编译我的简单OpenGl程序时，我得到了未定义的引用，但我不知道为什么，我虽然设置正确，但我猜不是。有人可以帮我解决我的问题吗？

我的代码：

#include <GL\glew.H>
#include <GLFW\glfw3.h>

int         windowWidth  = 980;
int         windowHeight = 640;

int Main()
{
    if (!glfwInit())
        return -1;

    glfwWindowHint(GLFW_SAMPLES, 4); // AA
    glfwWindowHint(GLFW_CONTEXT_VERSION_MAJOR, 3);
    glfwWindowHint(GLFW_CONTEXT_VERSION_MINOR, 3);
    glfwWindowHint(GLFW_OPENGL_PROFILE, GLFW_OPENGL_CORE_PROFILE);

    GLFWwindow* window = NULL;

    window = glfwCreateWindow(windowWidth, windowHeight, "Window", NULL, NULL);

    if (!window)
    {
        glfwTerminate();
        return -1;
    }

    glfwMakeContextCurrent(window);
}

控制台消息：

Answer 1

您需要链接到OpenGL库：libopengl32.a，因此您要将-lopengl32添加到构建命令，或opengl32添加到IDE的库中。您还应该链接到gdi32。（-lgdi32）

来源：http://www.glfw.org/docs/latest/build.html#build_link

Answer 2

您还必须链接到-lGL这些符号是OpenGL库的一部分。

Answer 3

确保在编译期间链接这些库。

对于GCC，添加-lGL -lglew以链接GL和GLEW库。
