NS-2 脚本不会编译产生无效的命令名称 "Agent/mUDP"

Question

我正在尝试在 Mac OS X El Capitan 上编译以下 ns-2 脚本。我使用 https://github.com/dhruvvyas90/ns-install-osx

中提供的说明安装了 ns-2

// Installation steps :
git clone https://github.com/dhruvvyas90/ns-install-osx.git
cd ns-install-osx
chmod +x install.sh && ./install.sh
Restart terminal.

它安装得很好，因为 ns 和 nam 命令可以从终端获得。

问题是我无法编译以下脚本：

set val(chan)           Channel/WirelessChannel   
set val(prop)           Propagation/TwoRayGround   
set val(netif)          Phy/WirelessPhy

我收到以下错误：

我该如何解决这个问题？

Answer 1

ns2 的 "mUDP" 添加：http://csie.nqu.edu.tw/smallko/ns2_old/tool_en.htm

NS-2 脚本不会编译产生无效的命令名称 "Agent/mUDP"

NS-2 script won't compile produces invalid command name "Agent/mUDP"
