NS2 is a popular discrete event simulator for simulating different types of networks. In this article i will show you how to install NS-2.34 on Ubuntu 11.04.  

Note: Please connect your pc to internet, it is very important because failure of connection may cause some error in installing ns2 or in some future work.

• Download ns2.34 from here. 

• Copy ns-allinone-withpath-2.34.tbz to /tmp directory.

       cd ns-allinone-2.34/

• Now, install the development files for X Windows plus the g++ compiler:

       sudo apt-get install xorg-dev g++ xgraph

• Fix the error in the linking of otcl by editing line 6304 of otcl-1.13/configure so that it reads                    

        SHLIB_LD="gcc -shared"
        instead of
        SHLIB_LD="ld -shared"

• Then, edit the file ns-2.34/tools/ranvar.cc and change the line 219 from

        return GammaRandomVariable::GammaRandomVariable(1.0 + alpha_, beta_).value() * pow (u, 1.0 / alpha_);
        to
        return GammaRandomVariable(1.0 + alpha_, beta_).value() * pow (u, 1.0 / alpha_);

• Next, change the lines 183 and 185 in file ns-2.34/mobile/nakagami.cc to read

        resultPower = ErlangRandomVariable(Pr/m, int_m).value();
        and
        resultPower = GammaRandomVariable(m, Pr/m).value(); 

• Install gcc-4.4 and g++-4.4 including dependencies using the code below:

        $ sudo apt-get install gcc-4.4 g++-4.4 
              If there is any occur while installing these than you can use

        here you can search it and easily download and install it. 

• Now, change the line 270 in tcl8.4.18/unix/Makefile.in that reads

        CC = @CC@ -V 4.4
         Make sure it is a capital V.

• Finally,run the command

         sudo ./install

• After installation type the following command in a terminal

          source /etc/profile.d/ns2.sh
