Hello arif,
STEP 1:
From terminal login as super user and do the following in order to install all the dependencies needed by ns-2:
Quote:
#yum install autoconf
#yum install automake
#yum install gcc-c++
#yum install libX11-devel
#yum install xorg-x11-proto-devel
#yum install libXt-devel
#yum install libXmu-devel
|
Now you have downloaded ns-allinone-2.35.tar.gz package on your machine, now you have to first extract the files of this package and install it:
STEP 2:
Quote:
# gunzip ns-allinone-2.35.tar.gz
# tar -xvf ns-allinone-2.35.tar
# cd ns-allinone-2.35
# ./install
|
STEP 3:
Now go to /etc directory and type:
Add the following lines to the end of it. Remember replace
/usr/local/ by your installation path like
/home/arif.
Code:
# LD_LIBRARY_PATH
OTCL_LIB=/usr/local/ns-allinone-2.35/otcl-1.12
NS2_LIB=/usr/local/ns-allinone-2.35/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:$USR_LOCAL_LIB
# TCL_LIBRARY
TCL_LIB=/usr/local/ns-allinone-2.35/tcl8.4.14/library
USR_LIB=/usr/lib
export TCL_LIBRARY=$TCL_LIB:$USR_LIB
# PATH
XGRAPH=/usr/local/ns-allinone-2.35/bin:/usr/local/ns-allinone-2.35/tcl8.4.13/unix:/usr/local/ns-allinone-2.35/tk8.4.13/unix
NS=/usr/local/ns-allinone-2.35/ns-2.35/
NAM=/usr/local/ns-allinone-2.35/nam-1.12/
PATH=$PATH:$XGRAPH:$NS:$NAM
Let it take effect immediately
source ~/.bashrc
Note: the step described above is important; otherwise, you cannot run ns successfully.
or you can restart your X windows.i.e. logout and then login, or reboot your system, to make it work.)
Now, the installation has been completed. If you try:
$ ns
Then a “%” will appear on the screen.type “exit” to quit the mode and back to “$”
If you miss out step 1 you may get the following errors:
Code:

If you miss step 3
At the prompt when you type ns you will get:
