ubuntu 12.04 安装NS2（2.35） 环境变量失败

对ubuntu不是很懂，别人叫来帮忙装NS2。硬的头皮去了。说说注意事项吧。

1.必要的软件要装，就如windows装游戏都要装的VC++2005什么的

#sudo apt-get remove gcc

# sudo apt-get install build-essential

# sudo apt-get install tcl8.4 tcl8.4-dev tk8.4 tk8.4-dev

# sduo apt-get install libxmu-dev libxmu-headers

2.解压缩 都是指令操作

# tar xvfz ns-allinone-2.35.tar.gz

3.安装

cd /home/administrator/ns-allinone-2.35（cd后面有空格）

sudo ./install

安装完成后提示

IMPORTANT NOTICES:
(1) You MUST put /home/administrator/ns-allinone-2.35/otcl-1.14, /home/administrator/ns-allinone-2.35/lib,
into your LD_LIBRARY_PATH environment variable.
If it complains about X libraries, add path to your X libraries
into LD_LIBRARY_PATH.
If you are using csh, you can set it like:
setenv LD_LIBRARY_PATH
If you are using sh, you can set it like:
export LD_LIBRARY_PATH=
(2) You MUST put /home/administrator/ns-allinone-2.35/tcl8.5.10/library into your TCL_LIBRARY environmental
variable. Otherwise ns/nam will complain during startup.
After these steps, you can now run the ns validation suite with
cd ns-2.35; ./validate

4.修改环境变量

sudo nano /etc/profile

打开后 最下面添加如下指令

export PATH="$PATH:/home/administrator/ns-allinone-2.35/bin:/home/administrator/ns-allinone-2.35/tcl8.5.10/unix:/home/administrator/ns-allinone-2.35/tk8.5.10/unix"
export LD_LIBRARY_PATH="$LD_LIBRARY_PATH:/home/administrator/ns-allinone-2.35/otcl-1.14, /home/administrator/ns-allinone-2.35/lib"
export TCL_LIBRARY="$TCL_LIBRARY:home/administrator/ns-allinone-2.35/tcl8.5.10/library "

！！！！！！！特别注意 “administrator”是自己电脑的用户名，不要直接复制粘贴，不然不会有用的。（我小白，所以耽误很多时间，唉~~~）！！！！！！

（查看添加成功可以输入  ecth $PATH,添加成功会有显示的）

然后

sudo source /etc/profile

最后输入ns

出现%就表示成功了

（本人小白，望大家谅解！）
