Question

我是编程和学习用Sublime Text 2中的C ++编写OpenGL代码的新手。我有javascript经验，我现在使用Sublime Text 2和MinGW来编译C ++代码。它使用普通的C ++代码运行得很好，但是使用OpenGL它会返回问题。我在MinGW安装了GLUT。

例如：我在youtube视频中找到了这个简单的代码：http://www.youtube.com/watch?v=SAmD_Aq1Un4

#include <GL/GLUT.h>
#include <iostream>

void render(void);

void keyboard(unsigned char c, int x, int y);

void mouse(int button, int state, int x, int y);

int main(int argc, char** argv) {
    glutInit(&argc, argv);
    glutInitDisplayMode(GLUT_DEPTH | GLUT_DOUBLE | GLUT_RGBA);
    glutInitWindowPosition(100, 100);
    glutInitWindowSize(640, 480);
    glutCreateWindow("Simple GLUT Application");

    glutDisplayFunc(render);    
    glutKeyboardFunc(keyboard);
    glutMouseFunc(mouse);

    glutMainLoop();
}

void keyboard(unsigned char c, int x, int y) {
    if (c == 27) {
        exit(0);
    }
}

void mouse(int button, int state, int x, int y) {
    if (button == GLUT_RIGHT_BUTTON) {
        exit(0);
    }
}

void render(void) {
    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    glBegin(GL_TRIANGLES);
        glColor3f(1, 0, 0);
        glVertex2f(-0.5, -0.5);
        glColor3f(0, 1, 0);
        glVertex2f(0.5, -0.5);
        glColor3f(0, 0, 1);
        glVertex2f(0.0, 0.5);
    glEnd();

    glutSwapBuffers();
}

当我构建文件时，它说明如下：

我是c ++，如果你想使用（在这个例子中是静态的）库，你必须链接它。在通常的英语中，您必须告诉编译器它可以在哪里找到库函数的实现。我不知道如何在您的编辑器中执行此操作，但通常会有一些称为链接器设置的内容，您可以在其中链接项目所需的所有库。有关详细信息see this wiki page
