Hi Gang,
Thanks for your answer.I found that those warnings were because of the
following two lines in .bashrc file:
unset TMP
unset TEMP
Removing these two directions eliminates warnings.
After removing all comments and the mentioned directions from .bashrc, I
changed the environment variables this way (thanks T. Issaraiyakul for his
helpful Slides on NS installation):
NSHOME=~/ns-allinone-2.35-RC6
OTCL_LIB=${NSHOME}/otcl-1.14
NS2_LIB=${NSHOME}/lib
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$OTCL_LIB:$NS2_LIB
export TCL_LIBRARY=${NSHOME}/tcl8.5.8/library
PATH=$PATH:${NSHOME}/ns-2.35:${NSHOME}/nam-1.15
And now the response to 'ns' command in Cygwin prompt is as follows:
mo...@mobin ~
$ ns
bash: ns: command not found
I don't know why this happens but I'm pretty sure that 'ns.exe' exists in
'ns-2.35' folder, which is declared in PATH.
Is there any suggestion to overcome this problem?
Thanks,
Mobin
