Installing Omnet in Ubuntu 10.10

To install Omnet on Ubuntu 10.10, the following are necessary

• Java (jdk)
• Gcc Compiler / G++ Compiler
• zlibraries and other components

Here are the instructions

• Download Omnet from http://www.omnetpp.org/  (the latest edition is 4.1)
• Download the omnet-xxx.tgz file (its for linux)
• Open the terminal, untar it to any folder in linux (in my case it is /home/pradeepkumar/) using the following command

tar zxvf omnet-xxx.tgz

• go to the folder by this command cd omnet-xx/ (the above command creates a folder and untar all the contents into it)
• execute the command ./configure
• you may get some errors like unavailability of packages and dependencies, execute the following command to download and install all the packages
• for running the following command, your machine has to be connected to the internet….

sudo apt-get install bison flex byacc zlib1g-dev tcl tk tcl8.4 tk8.4 tcl8.4-dev tk8.4-dev build-essentials libxmu-dev

• once all are installed, type again ./configure (now this command will give some information to create a path)
• Two paths has to be setup, PATH and TCL_LIBRARY
• put the paths in the above file, /home/pradeepkumar/.bashrc
• go to any line of that file and type export PATH=$PATH: <the path provided after configure command> and similarly export TCL_LIBRARY=<the path provided>
• Log off and log on (this is to detect the PATH variables)
• open terminal, go to omnet-xx/ and type

make

That’s it, the software is installed and it will give you the command to type omnetpp to run the software.
