#Installation (for Ubuntu 16.04)

##Network Simulator 2 (NS2) and TCL/TK

  1. Install NS2 from here
  2. Run the following commands in a terminal:
$ sudo apt-get update
$ sudo apt-get dist-upgrade
$ sudo apt-get update
$ sudo apt-get install gcc
$ sudo apt-get install g++-4.9
$ sudo apt-get install build-essential autoconf automake
$ sudo apt-get install tcl8.5-dev tk8.5-dev
$ sudo apt-get install perl xgraph libxt-dev libx11-dev libxmu-dev
$ sudo cp /home/abc/Downloads/ns-allinone-2.35.tar.gz /opt/
$ cd /abc/Downloads
$ tar -zxvf ns-allinone-2.35.tar.gz
$ cd ns-allineone-2.35
$ ./install
$ sudo gedit ~/.bashrc
  1. At this point in time, you will be having a text file open in Gedit. Copy the following lines at the end of the file as they are:

#LD_LIBRARY_PATH
OTCL_LIB=/opt/ns-allinone-2.35/otcl-1.14/
NS2_LIB=/opt/ns-allinone-2.35/lib/
USR_Local_LIB=/usr/local/lib/
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$OTCL_LIB:$NS2_LIB:$USR_Local_LIB

#TCL_LIBRARY
TCL_LIB=/opt/ns-allinone-2.35/tcl8.5.10/library/
USR_LIB=/usr/lib/
export TCL_LIBRARY=$TCL_LIBRARY:$TCL_LIB:$USR_LIB

#PATH
XGRAPH=/opt/ns-allinone-2.35/xgraph-12.2/:/opt/ns-allinone-2.35/bin/:/opt/ns-allinone-2.35/tcl8.5.10/unix/:/opt/ns-allinone-2.35/tk8.5.10/unix/
NS=/opt/ns-allinone-2.35/ns-2.35/
NAM=/opt/ns-allinone-2.35/nam-1.15/
export PATH=$PATH:$XGRAPH:$NS:$NAM

  1. Open a terminal in the ns-allinone-2.35 folder, and execute the following code:
$ source ~/.bashrc
$ sudo apt install g++-4.9
$ export CC=gcc-4.9 CXX=g++-4.9 && ./install
$ sudo apt install ns2

If you see a '%' sign after executing the last command, you are good to go.
