I apologise, in my previous message I forgot to edit the subject line.....:-)
>From the warning messages displayed, you have installed ns-allinone 2.28, not ns-2.28 (the latter is when you install it from the pieces). When you install it from the pieces, it does not display such a warning. The LD_LIBRARY_PATH is actually an extra set of directories, where the run-time shared library loader will look for any needed shared libraries when loading an executable. You can define multiple directories as the value for that variable separated with a colon (:) Specifically, the value of this environment variable (i.e the list of directories specified) is added to the beginning of** the existing list of compiled-in loader paths for a given executable, and any system default loader paths. You add this environment variable in the startup file of your login shell ( i.e. .bashrc for bash or .login for tcsh) specifying it as it is shown in the messages. An example of a specification for the LD_LIBRARY_PATH in one of my ns-allinone installations is shown below. I have put this variable (among others) in the .bashrc file in my home dir: export NS_HOME=/home/MIS_USER/ns-allinone-2.26 export LD_LIBRARY_PATH=$NS_HOME/tcl8.3.2/unix:$NS_HOME/tk8.3.2/unix:\ $NS_HOME/otcl-1.0a8:$NS_HOME/lib:$LD_LIBRARY_PATH Notice that I have put the home dir of ns-allinone in another env var, which I use in the specification of the LD_LIBRARY_PATH var. I Hope to have helped. P.S. For further information regarding this variable or its security implications when using it, you can check this link: http://www.visi.com/~barr/ldpath.html<http://www.visi.com/%7Ebarr/ldpath.html> Regards, -Fk -- Filippos N Kolovos Software Systems Analyst & Engineer M.Sc.
