我正在使用Ubuntu 14.04上的代码块开发一个关于OpenGl的项目，虽然我确信我已经下载了Gl / glut库，这是我在编译代码时遇到的错误：

以下是整个主要代码：
#include "game.hpp"
#include "painter.hpp"
#include <GL/glut.h>
Game game;
void display()
{
glClear(GL_COLOR_BUFFER_BIT);
game.draw();
glutSwapBuffers();
}
void mouse(int button, int state, int x, int y)
{
if (state == GLUT_UP)
{
switch (button)
{
case GLUT_LEFT_BUTTON:
game.open(x / Painter::CELL_WIDTH, y / Painter::CELL_HEIGHT);
break;
case GLUT_RIGHT_BUTTON:
game.mark(x / Painter::CELL_WIDTH, y / Painter::CELL_HEIGHT);
break;
}
glutPostRedisplay();
}
}
int main(int argc, char **argv)
{
glutInit(&argc, argv);
glutInitDisplayMode(GLUT_DOUBLE | GLUT_RGB);
glutInitWindowSize(Game::WIDTH * Painter::CELL_WIDTH, Game::HEIGHT * Painter::CELL_HEIGHT);
glutInitWindowPosition(100, 120);
glutCreateWindow("MineSweeper");
glClearColor(0, 0, 0, 1);
glMatrixMode(GL_PROJECTION);
glLoadIdentity();
glOrtho(0, Game::HEIGHT * Painter::CELL_HEIGHT, Game::WIDTH * Painter::CELL_WIDTH, 0, -1.0, 1.0);
glutDisplayFunc(display);
glutMouseFunc(mouse);
glutMainLoop();
}
感谢任何帮助，谢谢。
