You are not supposed to use root to build applications, in /home/name/.
`root' is for administrative purposes only !
One command can be done with sudo (or root) : make install
.. All other ns2 commands must be done as ordinary user.

Read the above thread : All the $ <some-command> means you do not use root.
I.e. '$' is the user commands prompt, '#' is the root prompt.

A warning is not an error. A warning is "an informative text" only.

Sir
Here are the installation places:
tcl8.4.5: /home/asma/Desktop/work/ns-allinone-2.28/{bin,include,lib}
tk8.4.5: /home/asma/Desktop/work/ns-allinone-2.28/{bin,include,lib}
otcl: /home/asma/Desktop/work/ns-allinone-2.28/otcl-1.9
tclcl: /home/asma/Desktop/work/ns-allinone-2.28/tclcl-1.16
ns: /home/asma/Desktop/work/ns-allinone-2.28/ns-2.28/ns

please what should i do to change it to the root diractory like you said to me .thank you sir for help.

# 34 .

Post #31 says "no root".

And you cannot move anything.
The executable 'ns' (and copies of ns) is hard coded to find libraries in
/home/asma/Desktop/work/ns-allinone-2.28/lib/ , and tcsh* in
/home/asma/Desktop/work/ns-allinone-2.28/bin/.

"Hard coded to find libraries and tcsh" also means,
that writing *PATH's into .bashrc makes no sense.

am sorry i was wrong sir ;

I have no idea. Lots of simulations will display similar warnings.
They can usually be ignored.

i checket ns-defaul.tcl file and it missed

Agent/myUDP set packetSize_ 1000

Tracefile set debug_ 0
! i should add it and make clean;make ns2.28.

# 38 : ns-defaul.tcl : Thank you.

Please attach your `ns-defaul.tcl' as 'ns-default.tcl.txt'.
Attachments : The paper clip tool in the 'Advanced Editor'.
( Only suffix .txt will do for a text file.)

Then I will make up a new patch "myevalvid2-ns228-patching-1.tar.gz",
to replace the old "myevalvid2-ns228-patch.tar.gz" ,
originally made from the @johnli files, post #42 →

# 40 : Thank you. Works perfectly.

A new "patch package", 'myevalvid2-ns228-patching-1.tar.gz' can be found here ..

Be sure that you make a copy of the new 'ns' to e.g. 'ns-myevalvid2-1'
.. and $ sudo cp ns-myevalvid2-1 /usr/local/bin/

* The simulation $ ns-myevalvid2-1 be_a01.tcl

i have ns-evalvid in usr/local/bin
the problem is when i update the ns-default.tcl
ns not considered the changes
