For any software development work in ubuntu, some software packages are needed. For example C/C++ will be needed by almost all the developmental work how to install the required libraries and needed softwares for development, here are the steps  You create a password for the super user sudo passwd Give the password of the default user and then give the root password twice. Once you install Ubuntu (any distro), just update the softwares by the following command: sudo apt-get update sudo apt-get install build-essential libxmu-dev  (the above line will install softwares of size nearly 56MB) This will install latest G++ compiler along with other developmental libraries.

Download NS2.35 from this link. http://sourceforge.net/projects/nsnam/files/allinone/ns-allinone-2.35/ns-allinone-2.35.tar.gz/download Copy the file to /home/yourhome (in my case it is, /home/pradeep/) Untar it using “ tar zxvf ns-allione-2.35.tar.gz ” (without quotes) “cd ns-allione-2.35/” (without quotes) “./install” (see the dot in the beginning) During the installation there may be a error in linkstate/ls.h, the location of ls.h is  “/home/pradeep/ns-allinone-2.35/ns-2.35/linkstate/ls.h” Open the file using gedit “gedit /home/pradeep/ns-allinone-2.35/ns-2.35/linkstate/ls.h” in line number 127, there will be a erase function, change it to this->erase and go to step 5. Once installation over, set the PATH and that’s it.
