Im having problems installing the program NS2. After ive installed it , it asks to do the following :-
into your PATH environment; so that you'll be able to
(1) You MUST put /usr/src/ns-allinone-2.27/otcl-1.8,
into your LD_LIBRARY_PATH environment variable.
If it complains about X libraries, add path to
your X libraries
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:
(2) You MUST put
/usr/src/ns-allinone-2.27/tcl8.4.5/library into your
variable. Otherwise ns/nam will complain during
(3) [OPTIONAL] To save disk space, you can now delete
and tk8.4.5. They are now installed under
After these steps, you can now run the ns validation
cd ns-2.27; ./validate
Ive run the followigng command : export $PATH = usr/src/ns-allinone-2.27/bin:/usr/src/ns-allinone-2.27/tcl8.4.5/unix
:/usr/src/ns-allinone-2.27/tk8.4.5/unix but it doesnt seem to have worked. Could anyone tell me the correct procedures as in the right coding so i can copy it in terminal (im sorry at the laziness but ive been trying this for the past month and am still getting wrong).
Also for future refrence is there a book or website which explains these types of things?
What i dont understand (coming from a windows background) what changing paths entail. Is it pointing to a particular area? Is it moving some directories into the scope of the computer? what does it do?
Sorry if its really basic.
