Ubuntu16.04 安装ns2

1.更新数据源

1.切换更新源

#sudo gedit /etc/apt/sources.list
 删除并改写为
deb http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse

2.

sudo apt-get  update          #更新源列表
sudo apt-get upgrade          #更新已经安装的包
sudo apt-get dist-upgrade     #更新软件，升级系统

2.安装

sudo apt-get install build-essential autoconf automake
sudo apt-get install tcl8.5-dev tk8.5-dev
sudo apt-get install perl xgraph libxt-dev libxmu-dev libx11-dev libxmu-dev

3.下载ns2.35

ns2.35网盘下载地址 https://pan.baidu.com/s/18HkGZvfcIEkJAW9nLfzh0Q
提取码：2rej
下载后置于 /home/用户名/Documents目录下，并解压

cd /home/用户名/Documents
tar xvfz ns-allinone-2.35.tar.gz
cd ns-allinone-2.35
cd ns-2.35/linkstate/ls.h
找到第137行 void eraseAll() { erase(baseMap::begin(), baseMap::end()); }
改为：void eraseAll() { this->erase(baseMap::begin(), baseMap::end()); }
保存退出
cd /home/用户名/Documents/ns-allinone-2.35
./install

等待出现下图

4. 配置环境变量

1. 打开新的terminal终端

2. sudo gedit ~/.bashrc

3. 在终端加上下面一段话，将其中的"toor"更换为自己的用户名，可通过终端命令 users 查看

   # LD_LIBRARY_PATH
   OTCL_LIB=/home/toor/Documents/ns-allinone-2.35/otcl-1.14/
   NS2_LIB=/home/toor/Documents/ns-allinone-2.35/lib/
   USR_Local_LIB=/usr/local/lib/
   export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$OTCL_LIB:$NS2_LIB:USR_Local_LIB
   
   #TCL_LIBRARY
   TCL_LIB=/home/toor/Documents/ns-allinone-2.35/tcl8.5.10/library/
   USR_LIB=/usr/lib/
   export TCL_LIBRARY=$TCL_LIBRARY:$TCL_LIB:$USR_LIB
   
   #PATH
   XGPATH=/home/toor/Documents/ns-allinone-2.35/xgraph-12.2/:/home/toor                          /Documents/ns-allinone-2.35/bin/:/home/toor/Documents/ns-allinone-2.35/tcl8.5.10/unix/:/home/toor/Documents/ns-allinone-2.35/tk8.5.10/unix
   NS=/home/toor/Documents/ns-allinone-2.35/ns-2.35/
   NAM=/home/toor/Documents/ns-allinone-2.35/nam-1.15/
   export PATH=$PATH:$XGRAPH:$NS:$NAM
   

4. 保存退出后， 执行 source ~/.bashrc

5.激活ns2

1. cd /home/用户名/Documents/ns-allinone-2.35/ns-2.35/
2. ./validate

6.验证

关闭终端，重启终端,输入ns,出现%,说明ns2安装成功

**注意：**环境变量配错的话，会提示“程序“ns”尚未安装。 此时请不要使用以下命令安装：
sudo apt-get install ns2
应该继续在步骤4中修改环境变量！

先重新打开一个新的终端：

cd /home/用户名/Documents/ns-allinone-2.35/ns-2.35/tcl/ex/
ns simple.tcl

倘若弹出动画演示框，则证明ns完全安装正确。
