安装ns2

首先,安装好对应的ubuntu版本后,先对系统的相关项进行更新

· 复制代码
sudo apt-get  update #更新源列表
sudo apt-get upgrade #更新已经安装的包

如果觉得速度太慢的话,可以更换国内源
编辑/etc/apt/sources.list文件

添加在代码最前面,任选其一即可
清华源

重新加载下资源

```·
source /etc/apt/sources.list
```

更新源

```·
sudo apt-get update
```

**下载相关依赖**

```·
sudo apt-get install build-essential
sudo apt-get install tcl8.5 tcl8.5-dev tk8.5 tk8.5-dev  #for tcl and tk
sudo apt-get install libxmu-dev libxmu-headers  #for nam
```

**安装ns2**

```·
tar xvfz ns-allinone-2.35.tar.gz -C /opt
cd /opt/ns-allinone-2.35
./install #进行安装
```

安装可能会报以下错:

```·
linkstate/ls.h:137:20: note: use 'this->erase' instead
make: *** [linkstate/ls.o] Error 1
Ns make failed!
```

解决:  

修改ls文件:ns-2.35/linkstate/ls.h 第137行  

将 void eraseAll() { erase(baseMap::begin(), baseMap::end()); }  

改为:

```·
void eraseAll() { this->erase(baseMap::begin(), baseMap::end()); }
```

保存后 ./install 即可  
**配置环境变量**

```·
gedit  ~/.bashrc
```

末尾添加以下内容(注意修改路径)

```·
#add path for ns2
export NS_HOME=/opt/ns-allinone-2.35 
export PATH=$PATH:$NS_HOME/bin:$NS_HOME/tcl8.5.10/unix:$NS_HOME/tk8.5.10/unix
export LD_LIBRARY_PATH=$NS_HOME/otcl-1.14:$NS_HOME/lib  
export TCL_LIBRARY=$NS_HOME/tcl8.5.10/library
```

**验证ns2安装**   

输入ns,出现%,说明ns2安装成功

# 安装nam

进入nam目录:

```·
cd /opt/ns-allinone-2.35/nam-1.15
```

运行配置

```·
sudo ./configure
```

这里可能会出现以下错误:

    configure: error: Installation of tcl seems incomplete or can't be found automatically.
    Please correct the problem by telling configure where tcl is
    using the argument --with-tcl=/path/to/package
    (perhaps after installing it),
    or the package is not required, disable it with --with-tcl=no.

指定版本号即可

```·
sudo ./configure --with-tcl-ver=8.5
```

更新nam

```·
sudo make
```

最后

```·
sudo make install
```

最后这里可能会出现

    /usr/bin/install -c -m 755 nam /usr/local/bin

运行即可

```·
sudo /usr/bin/install -c -m 755 nam /usr/local/bin
```

命令行输入nam弹出nam console说明nam安装成功  
**运行测试**

cd /opt/ns-allinone-2.35/ns-2.35/tcl/ex/
ns simple.tcl

复制代码
运行时可能会出现以下问题

解决:权限放开

```·
sudo chmod  777 out.tr

解决:权限放开

· 复制代码
sudo chmod  777 out.nam
