hello frens can any one tell me wt this command telling and hw to include this path in detail .plz


Next step is to link LD_LIBRARY_PATH environment variable by giving following commands: (if
you are using ‘sh’ or ‘bash’ – as in my case).
%export LD-LIRARY-PATH=/home/raja/NS2/ ns-allinone-2.34/bin
%export LD-LIRARY-PATH=/home/raja/NS2/ ns-allinone-2.34/lib
%export TCL-LIRARY=/home/raja/NS2/ ns-allinone-2.34/tcl8.4.11/library
OR (if you are using ‘cshrc’)
%setenv LD-LIRARY-PATH /home/raja/NS2/ ns-allinone-2.34/bin
%setenv LD-LIRARY-PATH /home/raja/NS2/ ns-allinone-2.34/lib
%setenv TCL-LIRARY /home/raja/NS2/ ns-allinone-2.34/tcl8.4.11/library

None of the above is required in Linux. ( Usually.)
Also impossible to do if you have more than one version of ns-allinone-2.xx.

The binary 'ns' is hard coded to know where its libraries are located.

Actions to have ns in a system PATH :
cd ns-allinone-2.34/ns-2.34/
su ( or sudo )
make install
.... And 'ns' will be copied to /usr/local/bin/.
( The same 'make install' can be done with nam.)
