Download ns-2.35 from the website.
http://sourceforge.net/projects/nsnam...
Since ns2.35 is too old (2011) and hence it will work on the gcc and g++ version 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 infomration 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 any blank space between the paths....
$ source .bashrc
$ns
% indicates it install successfully.
$nam
a window gets popped up
It works well.
