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

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

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

sudo chmod  777 out.nam

运行结果：
