glfw 错误与 glfwWindowHint [英] glfw Errors with glfwWindowHint

问题描述

我已经尝试过使用 this 教程，但没有成功.我不知道为什么它不起作用.我正在使用 Ubuntu 14.04 和 GNU G++ 命令.

I have tried fallowing this tutorial and it did not work. I do not know why it is not working. I'm using Ubuntu 14.04 and GNU G++ command.

代码:

#include <GLFW/glfw3.h>

int main(void) {
    glfwInit();
    glfwWindowHint(GLFW_CONTEXT_VERSION_MAJOR, 3);
    glfwWindowHint(GLFW_CONTEXT_VERSION_MINOR, 2);
    glfwWindowHint(GLFW_OPENGL_PROFILE, GLFW_OPENGL_CORE_PROFILE); 
    glfwWindowHint(GLFW_OPENGL_FORWARD_COMPAT, GL_TRUE);

    glfwWindowHint(GLFW_RESIZABLE, GL_FALSE);


    GLFWwindow* window = glfwCreateWindow(800, 600, "OpenGL", NULL, NULL);

    glfwMakeContextCurrent(window);

    while(!glfwWindowShouldClose(window)) {
            glfwSwapBuffers(window);
            glfwPollEvents();
    }

    glfwTerminate();
}

终端:

command: g++ display.cpp -lglfw -o display.out
/tmp/cci33O9I.o: In function `main':
display.cpp:(.text+0x18): undefined reference to `glfwWindowHint'

推荐答案

你不应该链接到 glfw，而应该链接到 glfw3.如这里:

You should not link to glfw, but link to glfw3. As here:

g++ display.cpp -lglfw3 -o display.out
