Question

我想在CygWin下安装OpenGL库。我添加了Cygwin软件包：tiff-opengl，libQtOpenGL4，libQtOpenGl4-devel。可能我不需要最后2个包装 - 我安装它们以尝试运行OpenGL。我想用OpenGL编写的程序名为test15.c：

 #include <GL/gl.h>
 #include <GL/glut.h>
 void display()
{
}

int main(int argc, char **argv)
{
      glutInit(&argc, argv);
      glutDisplayFunc(display);
      glutMainLoop();
}

但是，我收到了所有这些错误消息。

如何使用OpenGL编译代码？
