记一次ns3的安装过程

官方安装教程：https://www.nsnam.org/wiki/Installation

推荐使用Ubuntu18.04，Ubuntu20.04有些依赖无法下载。

准备工作

# 如果下载速度很慢，可以更换源
sudo sed -i 's#archive.ubuntu.com#mirrors.aliyun.com#g' /etc/apt/sources.list
# 下面的一定要执行
sudo apt update
sudo apt upgrade

# 建议安装完，copy全部，再执行一遍，看有没有漏掉的。

下载源文件并进行解压安装

下载地址：https://www.nsnam.org/releases/

tar xjf ns-allinone-3.31.tar.bz2 # 解压
chmod -R 777 ns-allinone-3.31 # 修改权限
ls
cd ns-allinone-3.31 # 切换到解压目录下

./build.py --enable-examples --enable-test

输出如下

重点关注下列输出，涉及到能否支持Python。

Python API Scanning Support   : not enabled (Missing 'pygccxml' Python module)
Python Bindings               : enabled

pip3 install pygccxml

cd ns-3.31
./waf --build-profile=debug --enable-examples --enable-test configure

pip3 install CastXML #安装好后，重启一下。

./test.py #问题解决了，继续安装
./waf --run hello-simulator # 验证是否安装成功

其它问题

 pip3 install PyBindGen
