Installation of NS-2.34 on Ubuntu 11.04 and 12.04

Ø  if you are installing ns-allinone-2.34 in the root login of the desktop you should do the  following steps

Step: 1

Ø   Download ns-allinone-2.34.tar.gz file  from

      http://sourceforge.net/projects/nsnam/files/

Ø   Copy the ns-allinone-2.34.tar.gz file in to the desktop directory.

Step: 2

Ø   Then give cd Desktop in the Terminal Window

Ø   Extract the files in the same folder using extract option or the command in the terminal as

      root/ Desktop >tar zxvf  ns-allinone-2.34.tar.gz

Ø   The files will be extracted in the newly created folder as ns-allinone-2.34.

Ø   Then Install the development files for X Windows plus the g++ compiler:
     

root/ Desktop >apt-get install xorg-dev g++ xgraph

Step: 3

Ø  To avoid installation error before installation you should do the following changes in the following file and save it

Ø   In otcl-1.13/configure  

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

Ø   Then, edit the file in the 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_);

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

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

Ø   Next add a bellow line after line 64 in ns-2.34/mac/mac-802_11Ext.h

      #include <stddef.h>

Ø   To Install gcc-4.4 and g++-4.4 including dependencies using the below :
      root/ Desktop > apt-get install gcc-4.4 g++-4.4

Ø   Then change the line 270 in tcl8.4.18/unix/Makefile.in

      change into

      CC = gcc-4.4

      instead of

      CC = @CC@

Ø   so it uses gcc version 4.4

Step: 4

Ø   for installation  of NS do the below mentioned in the terminal window

                root/ Desktop/ ns-allinone-2.34>./install

Ø   This command will run for 10-15 minutes. If it is a successful installation you will be getting IMPORTANT NOTICE notes (detailing about the paths to set)

Step: 5

Ø  After installation of NS you should edit the bash file to set path for that in the desktop directory give

    gedit ~/.bashrc

Ø   The in the opened file add this followings in the end of the file and Save it

     # LD_LIBRARY_PATH

    OTCL_LIB=/root/Desktop/ns-allinone-2.34/otcl-1.13

    NS2_LIB=/root/Desktop/ns-allinone-2.34/lib

    X11_LIB=/usr/X11R6/lib

    USR_LOCAL_LIB=/usr/local/lib

    export  LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$OTCL_LIB:$NS2_LIB:$             X11_LIB:$USR_LOCAL_LIB

# TCL_LIBRARY

    TCL_LIB=/root/Desktop/ns-allinone-2.34/tcl8.4.18/library

    USR_LIB=/usr/lib

    export TCL_LIBRARY=$TCL_LIB:$USR_LIB

    # PATH

    XGRAPH=/root/Desktop/ns-allinone-2.34/bin:/root/Desktop/ns-allinone-    2.34/tcl8.4.18/unix:/root/Desktop/ns-allinone-2.34/tk8.4.18/unix

    NS=/root/Desktop/ns-allinone-2.34/ns-2.34/

    NAM=/root/Desktop/ns-allinone-2.34/nam-1.14/

    PATH=$PATH:$XGRAPH:$NS:$NAM

Ø   Then it takes effect immediately you should give below mentioned in desktop directory using terminal.

source ~/.bashrc

Step: 6

Ø  Now close all the terminal and open a new terminal and get into the folder root/ns-allinone-2.34 and give ns command and you will be getting each time as below after pressing ENTER key. This indicates that the installation is complete.

   Root/ns-allinone-2.34>ns

  %

                            %exit

Step: 7
