在win7_64bit + ubuntu-12.04-desktop-amd64+VMware-workstation-full-10.0.1-1379776平台上安装ns-allinone-2.35
step1. ns-allinone-2.35的下载地址：http://www.isi.edu/nsnam/ns/ns-build.html#allinone
step2. 在虚拟机中打开terminal。打开terminal的快捷方式：ctr+shift+t
step3. #sudo apt-get update //新安装的系统先运行一下，避免出现软件依赖的错误
step4. # sudo apt-get install build-essential
step5. # sudo apt-get install tcl8.4 tcl8.4-dev tk8.4 tk8.4-dev
step6. # sudo apt-get install libxmu-dev libxmu-headers
step7. 先将 ns-allinone-2.35.tar.gz安装包复制到：/Home, 再解压： tar -zxf ns-allinone-2.35.tar.gz。也可手动解压安装包。( 注意：如采用命令：sudo tar -xzf ns-allinone-2.35.tar.gz 进行加压，解压后的文件夹会有锁的标识)
step8. cd ns-allinone-2.35 #定位到安装目录(解压之后的文件)
step9. ./install #开始安装(注意：如采用命令：sudo ./install 进行安装，安装过程中创建的文件夹会有锁的标识)

安装完成后提示
IMPORTANT NOTICES:
(1) You MUST put /home/ub-administrator/ns-allinone-2.35/otcl-1.14, /home/ub-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/ub-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
step10. sudo gedit ~/.bashrc #打开。bashrc文件，以便更改环境变量
step11. 在文件的尾部加入一下内容：
export PATH=$PATH:/home/ub-administrator/ns-allinone-2.35/bin:/home/ub-administrator/ns-allinone-2.35/tcl8.5.10/unix:/home/ub-administrator/ns-allinone-2.35/tk8.5.10/unix
export LD_LIBRARY_PATH=/home/ub-administrator/ns-allinone-2.35/otcl-1.14:/home/ub-administrator/ns-allinone-2.35/lib
export TCL_LIBRARY=/home/ub-administrator/ns-allinone-2.35/tcl8.5.10/library
注意：红色字体的内容来自安装完后的提示，即为You MUST put后面的路径。
step12. 保存.bashrc后关闭terminal，并重新打开terminal，再输入ns，出现%，则安装成功。
此外，如果输入：ns /home/ub-administrator/ns-allinone-2.35/ns-2.35/tcl/ex/simple.tcl 提示：
---------------------------------------------------start 信息提示---------------------------------------------------
running nam...
ub-administrator@ubadministrator-virtual-machine:~$ nam: Can't find a usable tk.tcl in the following directories:
/home/ub-administrator/ns-allinone-2.35/tcl8.5.10/library/tk8.5 /home/ub-administrator/ns-allinone-2.35/tcl8.5.10/tk8.5 ./lib/tk8.5 /home/ub-administrator/ns-allinone-2.35/lib/tk8.5 ./library
...................................
This probably means that tk wasn't installed properly.
---------------------------------------------------end 信息提示---------------------------------------------------
这是因为没有安装nam. 输入：sudo apt-get install nam 安装成功后再验证即可。
如果遇到问题，可以重新执行 ./install。
如果执行上述命令不成功（如出现Failed to fetch http://…..），一般是由于直接使用国外的源无法连接的原因导致的，此时需要换源：
首先，打开源文件，命令为：sudo gedit /etc/apt/sources.list，修改后的源为：
deb http://old-releases.ubuntu.com/ubuntu precise main universe restricted multiverse
deb http://old-releases.ubuntu.com/ubuntu precise-security universe main multiverse restricted
deb http://old-releases.ubuntu.com/ubuntu precise-updates universe main multiverse restricted
deb http://old-releases.ubuntu.com/ubuntu precise-proposed universe main multiverse restricted
