Fedora15或Ubuntu11.04版本安装ns2.34

 1、下载ns（network simulation）安装包

到网站http://www.isi.edu/nsnam/ns/ns-build.html下载最新的ns-allinone套件，现在使用的是ns-allinone-2.34.tar.gz

2、配置系统环境

安装依赖包

＃yum install gcc-c++
＃yum install libX11-devel
＃yum install xorg-x11-proto-devel
＃yum install libXt-devel
＃yum install libXmu-devel

 3、安装ns-allinone-2.34.tar.gz

3.1、安装目录为：主文件夹”/home/jean"（用户名为jean）

#解压
sudo tar xvfz ns-allinone-2.34.tar.gz
＃进入tk8.4.18文件夹
cd ns-allinone-2.34/tk8.4.18/
#wget用ftp下载包
wget ftp://ftp.swin.edu.au/gentoo-portage...astevent.patch
#重新安装
patch -p0 < tk-8.4-lastevent.patch
#返回ns-allinone-2.34
cd ../
#设定CC为需要的gcc版本，和CXX为需要的g++版本（ns-allinone-2.34里面的C语言编译版本是4.0以下的）
export CC=gcc34 CXX=g++34
#安装
./install

最后出现：

IMPORTANT NOTICES:

(1) You MUST put /home/jean/ns-allinone-2.34/otcl-1.13, /home/jean/ns-allinone-2.34/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 <paths>
    If you are using sh, you can set it like:
		export LD_LIBRARY_PATH=<paths>

(2) You MUST put /home/jean/ns-allinone-2.34/tcl8.4.18/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-2.34; ./validate

For trouble shooting, please first read ns problems page 
http://www.isi.edu/nsnam/ns/ns-problems.html. Also search the ns mailing list archive

4、设置环境变量

#在/home/jean目录下，运行
sudo gedit .bashrc
#在第8行输入
PATH="$PATH:/home/jean/ns-allinone-2.34/bin:/home/jean/ns-allinone-2.34/tcl8.4.18/unix:/home/jean/ns-allinone-2.34/tk8.4.18/unix"
LD_LIBRARY_PATH="/home/jean/ns-allinone-2.34/otcl-1.13:/home/jean/ns-allinone-2.34/lib"
TCL_LIBRARY="$TCL_LIBRARY:/home/jean/ns-allinone-2.34/tcl8.4.18/library"

如图：

5、运行

打开新的终端：输入

ns

若出现%号，则安装成功

用一个例子试试：

ns ns-allinone-2.34/ns-2.34/tcl/ex/simple.tcl

 出现如图所示：
