Where is your program supposed to be starting? Your program has no entrypoint, it does not know where you want it to begin from, or what to do.
You're following a tutorial in the wrong way.

int main(int argc,char*argv[])

glutInit(&argc,argv);//对glut进行初始化 这个函数必须在其他的Glut使用前调用一次 格式死板
glutInitDisplayMode(GLUT_RGB|GLUT_SINGLE);//设置显示方式；rgb使用RGB颜色；使用单缓冲
glutInitWindowPosition(683,384);//设置窗口在屏幕中的位置
glutInitWindowSize(200,200);//窗口大小
glutCreateWindow("one");//根据前面信息创建一个窗口需要调用glutmainloop才看到窗口
glutDisplayFunc(&myDisplay);//需要画图时请调用mydisplay函数
glutMainLoop();//能够显示窗口
return 0;

can you help me?

At which point in the program does it crash?
Do you have any warnings while compiling?
