Ns2 Workshop 17-18 Department Of Computer Applications, SVCE Installing Network Simulator (ns2.34) in Ubuntu10.10 PROCEDURE : Step1: Download ns-allinone-2.34 package from this . I will be using ns version 2.34. Step2: Place the ns-allinone-2.34.tar.gz file in your home folder(/home/svce in my case). Right click on the package and extract the contents in the same home folder. Step3: Next, open the Terminal(Applications–>Accessories–>Terminal in ubuntu) Step4: Change to ns-allinone-2.34 directory $ cd /home/svce/ns-allinone-2.34 Step5: First, Install the dependencies $ sudo apt-get install build-essential autoconf automake libxmu-dev gcc-4.3 Note that we are downgrading the gcc version, as ns2.34 works well with gcc4.3 Edit Makefile.in found at this location ns-allinone-2.34/otcl-1.13/Makefile.in as follows: Find the line that says: CC= @CC@ and change it to: CC= gcc-4.3 Step6: Begin ns2.34 installation $ sudo su # ./install

Step7: Once the installation is successful i.e. without any errors, we need to add the path information to the file ~/.bashrc $ gedit ~/.bashrc

Step8: Append the following lines to the file ~/.bashrc # LD_LIBRARY_PATH OTCL_LIB=/home/svce/ns-allinone-2.34/otcl-1.13 NS2_LIB=/home/svce/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:$USR_LOCA L_LIB # TCL_LIBRARY TCL_LIB=/home/svce/ns-allinone-2.34/tcl8.4.18/library USR_LIB=/usr/lib export TCL_LIBRARY=$TCL_LIB:$USR_LIB # PATH XGRAPH=/home/svce/ns-allinone-2.34/bin:/home/svce/ns-allinone2.34/tcl8.4.18/unix:/home/svce/ns-allinone-2.34/tk8.4.18/unix # Note: the above two lines starting from XGRAPH should come in the same line NS=/home/svce/ns-allinone-2.34/ns-2.34/ NAM=/home/svce/ns-allinone-2.34/nam-1.14/ PATH=$PATH:$XGRAPH:$NS:$NAM Here replace /home/svce with the path to your home folder. Step9: For the changes to take effect immediately, do the following: $ source

~/.bashrc

Thats all! type ns to see % and type nam to show the nam startup window. This shows your installation has been successful.

Thank You
