$ sudo apt update For any GPG error, include the following command $ sudo apt update $ sudo apt install gcc-4.8 g++-4.8 Download ns-2.35 from the website. http://sourceforge.net/projects/nsnam/files/allinone/ns-allinone-2.35/ns-allinone-2.35.tar.gz/download Since ns2.35 is too old (2011) and hence it will work on the gcc and g++ versions of 4.8. So we need to change the default gcc to gcc-4.8 and g++ to g++-4.8 Here are the files that need to be modified. Make the changes in the following files @CC@ to be replaced with gcc-4.8 @CPP@ to be replaced with g++-4.8 ns-allinone-2.35/Makefile.in /home/pradeepkumar/ns-allinone-2.35/otcl-1.14/Makefile.in nam-1.15/Makefile.in xgraph-12.2/Makefile.in all changes were made. In all the above places, change @CC@ to gcc-4.8 and @CPP@ @CXX@ to g++-4.8 Open the file ns-2.35/linkstate/ls.h in line number 137, change the line erase to this (hyphen and greater than symbol) erase Run the installation now Open a terminal $ cd ns-allinone-2.35/ $ ./install Once the installation is over, Set the PATH and LD_LIBRARY_PATH information in the file located at open another terminal and issue the following command. $ gedit /home/pradeepkumar/.bashrc export PATH=$PATH:/home/pradeepkumar/ns-allinone-2.35/bin:/home/pradeepkumar/ns-allinone-2.35/tcl8.5.10/unix:/home/pradeepkumar/ns-allinone-2.35/tk8.5.10/unix export LD_LIBRARY_PATH=/home/pradeepkumar/ns-allinone-2.35/otcl-1.14:/home/pradeepkumar/ns-allinone-2.35/lib The field separator is a colon: here and there should not be any blank space between the paths.... $ source .bashrc $ns % indicates it installs successfully. $nam a window gets popped up (as shown in the following Figure.) It works well.
