Question

I run ns-2.35 on my Ubuntu 12.10

While I finished installing my ns2 and tried to run via "sudo ns xxx.tcl", it showed on the screen saying that there was no ns2 on my computer and I have to use "apt-get install ns2". I used it, and then it was installed successfully.

Now I modify some .cc files and recompile my ns2, and it is successful, too.

But the problem is that the results are not modified as I want. In fact, the result doesn't change. It seems my modification doesn't really change anything in my ns2. Why? There's no error in my installation or compilation? I am so confused. Is there anyone face the same problem? Thanks in advance!

Was it helpful?

Solution

I think your installed ns2 is not in your bash_profile path. execute which ns in terminal. it displays which ns is currently working. If it is usr/bin its default ns .now give path to your ns using PATH command. hope it helps

OTHER TIPS

For compiling your changes go to these steps: 1. firstly in terminal goto your ns2.XX folder then do following commands 2. make clean 3../configure 4.make 5.sudo make install 6.close terminal and open it again 7. run your tcl scripts.

hope it helps ..!! Enjoy

1) Download 'ns-allinone-2.35' from : http://sourceforge.net/projects/nsnam/files/allinone/ns-allinone-2.35/ns-allinone-2.35.tar.gz/download

2) Extract the downloaded zip file 'ns-allinone-2.35.tar.gz file' to desktop.

3) Now you need to download some essential packages for ns2,these packages can be downloaded by using the following command : applications>accessories>terminal or dashhome>trminal then type the below line on the terminal window

     "sudo apt-get install build-essential autoconf automake libxmu-dev libtool gcc"

     or type this command

     "sudo apt-get install autoconf automake gcc g++ build-essential libxmu-dev libtool libxt-dev"

4) Now change your directory(here i have already extracted the downloaded files to desktop,so my location is desktop) type the following codes in the command window to install NS2.

     cd Desktop   
     cd ns-allinone-2.35
     ./install

                          The installation procedure will take a few minutes..........

5) After compleating the installation type the following command in the command window

      gedit ~/.bashrc

6) Now an editor window appears,please copy and paste the follwing codes in the end of the text file (note that '/home/abhiram/Desktop/ns-allinone-2.35/octl-1.14' in each line in the below code should be replaced with your location where the 'ns-allinone-2.35.tar.gz'file is extracted)

  # LD_LIBRARY_PATH
  OTCL_LIB=/home/abhiram/Desktop/ns-allinone-2.35/otcl-1.14
  NS2_LIB=/home/abhiram/Desktop/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=/home/abhiram/Desktop/ns-allinone-2.35/tcl8.5.10/library
 USR_LIB=/usr/lib
 export TCL_LIBRARY=$TCL_LIB:$USR_LIB

 # PATH
 XGRAPH=/home/abhiram/Desktop/ns-allinone-2.35/bin:/home/abhiram/Desktop/ns-allinone-2.35/tcl8.5.10/unix:/home/abhiram/Desktop/ns-allinone-2.35/tk8.5.10/unix
 NS=/home/abhiram/Desktop/ns-allinone-2.35/ns-2.35/
 NAM=/home/abhiram/Desktop/ns-allinone-2.35/nam-1.15/
 PATH=$PATH:$XGRAPH:$NS:$NAM

7) Save and close the text editor and then type the following command on the terminal

   source ~/.bashrc

8) Close the terminal window and start a new terminal window and now change the directory to ns-2.35 and validate ns-2.35 by exicuting the following command ( it takes 30 to 45 minutes)

    cd ns-2.35
    ./validate

9) If the installation is successful, then you will be able to see % at the command prompt while typing the following command

    ns

10) Now type

    exit
