我目前所做的

大学计算机网络课程要求安装 Network Simulator 2。但我费了很大劲才安装成功。

我目前所做的

  • 已从以下位置下载 ns2 二进制文件这里

  • 已执行这些命令（基本上安装所需的依赖项）

sudo apt-get install gcc
sudo apt-get install make
sudo apt-get install libx11-dev
sudo apt-get install xorg-dev
  • 已执行这些命令来安装软件
tar xvfzns-allinone-2.35.tar.gz
cd ns-allinone-2.35
sudo ./install

到目前为止，编译过程都很顺利：

我见过这Stack Overflow 上的问题，我尝试了建议的解决方案，但对我不起作用。有人可以指导我该怎么做吗？我一周后要考试，情况很紧急。

Ubuntu 18.04，只需执行以下操作：sudo apt install g++-4.8 https://packages.ubuntu.com/search?suite=default§ion=all&arch=any&keywords=g%2B%2B-4.8&searchon=names...请注意，您可以同时安装任意数量的 gcc 版本。其他示例https://drive.google.com/drive/folders/1xVEATaYAwqvseBzYxKDzJoZ4-Hc_XOJm?usp=sharing

构建 ns-2.35：

tar xvf ns-allinone-2.35_gcc5.tar.gz    (2014 update)

https://drive.google.com/file/d/0B7S255p3kFXNVVlxR0ZNRGVORjQ/view?usp=sharing

cd ns-allinone-2.35/
export CC=gcc-4.8 CXX=g++-4.8 && ./install
cd ns-2.35/
sudo make install
