ns-3 NetAnim遇到了一个问题

安装好了 NetAnim 之后，使用NS3原有例子 third.cc ，在 Simulator::run() 前面添加如下语句：

AnimationInterface anim("third.xml");

在目录：/home/wasdns/Documents/NS3/ns-3.17 Terminal 执行：./waf --run scratch/third

生成xml文件：third.xml

打开 NetAnim 选择刚才的xml文件，正满心欢喜的想说解决了，出现了如下问题：

更新

在将XML文件第一行改成ns-3.17后，它又给出了提示：

于是，再次利用 vim 编辑器将第一行改为：

<anim ver="netanimation">

ns-3的一个小程序就跑起来了。

顺便贴一下跑的结果(Terminal)：
