"Please put /home/yahya/ns-allinone-2.34/bin:/home/yahya/ns-allinone-2.34/tcl8.4.18/unix:/home/yahya/ns-allinone-2.34/tk8.4.18/unix
into your PATH environment; so that you'll be able to run itm/tclsh/wish/xgraph.

IMPORTANT NOTICES:

(1) You MUST put /home/yahya/ns-allinone-2.34/otcl-1.13, /home/yahya/ns-allinone-2.34/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 <paths>
If you are using sh, you can set it like:
export LD_LIBRARY_PATH=<paths>

(2) You MUST put /home/yahya/ns-allinone-2.34/tcl8.4.18/library into your TCL_LIBRARY environmental
variable. Otherwise ns/nam will complain during startup.


After these steps, you can now run the ns validation suite with
cd ns-2.34; ./validate

For trouble shooting, please first read ns problems page
http://www.isi.edu/nsnam/ns/ns-problems.html. Also search the ns mailing list archive
for related posts."

PLZ any one know answer me!!

1. Nobody is being paid to help you so please be patient. Repeated postings demanding attention is not a good idea.
2. You need to follow the instructions about putting /home/yahya/ns-allinone-2.34/bin:/home/yahya/ns-allinone-2.34/tcl8.4.18/unix:/home/yahya/ns-allinone-2.34/tk8.4.18/unix in the PATH environmental variable. Then follow the other instructions involving the other libraries.

3. "put" means place a command like in your ~/.profile file.
jdk

None of the above path settings are required. ( Usually.)

The easy way :
cd ns-allinone-2.34/ns-2.34/ && sudo make install
&& cd ../nam-1.14/ && sudo make install

... Then you have 'ns' and 'nam' in a system path : /usr/local/bin/.

Thank you very much for help
