How to install ns2 on Red Hat Linux

The credit goes to Credits (original post)

To install ns 2.27 in Red hat, there are following steps: 

1. tar -xzf *
2. ./install
3. change .bash_profile and add some environment variables. put /home/zhibinwu/ns-allinone-2.27/bin:/home/zhibinwu/ns-allinone-2.27/tcl8.4.5/unix:/home/zhibinwu/ns-allinone-2.27/tk8.4.5/unix into your PATH environment; so that you’ll be able to run itm/tclsh/wish/xgraph.
   IMPORTANT NOTICES:

   (1) You MUST put /home/zhibinwu/ns-allinone-2.27/otcl-1.8, /home/zhibinwu/ns-allinone-2.27/lib,
    into your LD_LIBRARY_PATH environment variable.
    If it complains about X libraries, add path to your X libraries
    into LD_LIBRARY_PATH.
    If you are using csh, you can set it like:
    setenv LD_LIBRARY_PATH ....
    If you are using sh, you can set it like:
    export LD_LIBRARY_PATH=....
   
   (2) You MUST put /home/zhibinwu/ns-allinone-2.27/tcl8.4.5/library into your TCL_LIBRARY environmental
    variable. Otherwise ns/nam will complain during startup.
   
   (3) [OPTIONAL] To save disk space, you can now delete directories tcl8.4.5
    and tk8.4.5. They are now installed under /home/zhibinwu/ns-allinone-2.27/{bin,include,lib}

   so , finally the bash_profile is like this:

   PATH=$PATH:$HOME/bin:/home/zhibinwu/ns2/ns-allinone-2.27/bin:/home/zhibinwu/ns2/ns-allinone-2.27/tcl8.4.5/unix:/home/zhibinwu/ns2/ns-allinone-2.27/tk8.4.5/unix
   
   export LD_LIBRARY_PATH=/home/zhibinwu/ns2/ns-allinone-2.27/otcl-1.8:home/zhibinwu/ns2/ns-allinone-2.27/lib
   
   export TCL_LIBRARY=/home/zhibinwu/ns2/ns-allinone-2.27/tcl8.4.5/library

4. cd ns-2.27; ./validate

 

Note: The ns installation needs x-develop package. Otherwise, it will fail to build TCL TK.
