Hi Teerawat,
Thank you for following this topic.This is my current .bashrc config:
NSHOME=~/NS2/ns-allinone-2.35-RC3
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 the following lines show what my problem is, including the information
you asked for.
administra...@parsvictor ~
$ ./ns
bash: ./ns: No such file or directory
administra...@parsvictor ~
$ pwd
/home/Administrator
administra...@parsvictor ~
$ ls
NS2
administra...@parsvictor ~
$ cd NS2
administra...@parsvictor ~/NS2
$ ls
ns-allinone-2.35-RC6 ns-allinone-2.35-RC6.tar.gz
administra...@parsvictor ~/NS2
$ cd ns-allinone-2.35-RC6
administra...@parsvictor ~/NS2/ns-allinone-2.35-RC6
$ ls
INSTALL.WIN32 dei80211mr-1.1.4 lib otcl-1.14 tclcl
zlib-1.2.3
README gt-itm nam-1.15 sgb tclcl-1.20
bin include ns-2.35 share tk8.5.8
cweb install otcl tcl8.5.8 xgraph-12.2
administra...@parsvictor ~/NS2/ns-allinone-2.35-RC6
$ cd ns-2.35
administra...@parsvictor ~/NS2/ns-allinone-2.35-RC6/ns-2.35
$ ./ns
% puts "Hello World!"
Hello World!
%
administra...@parsvictor ~/NS2/ns-allinone-2.35-RC6/ns-2.35
$ echo $PATH
/usr/local/bin:/usr/bin:/bin:/cygdrive/c/Tcl/bin:/cygdrive/c/Windows/system32:/c
ygdrive/c/Windows:/cygdrive/c/Windows/System32/Wbem:/home/Administrator/NS2/ns-a
/nam-1.15/home/Administrator/NS2/ns-allinone-2.35-RC3
It's clear that there is a missing delimiter between the last two paths in
" echo $PATH " response.I though it might be because of ${NSHOME} and it was
cause when I replaced " ${NSHOME}/ns-2.35:${NSHOME}/nam-1.15 " with "
~/NS2/ns-allinone-2.35-RC3/ns-2.35:~/NS2/ns-allinone-2.35-RC3/nam-1.15 " the
response to echo $PATH have changed this way:
administra...@parsvictor ~
$ echo $PATH
/usr/local/bin:/usr/bin:/bin:/cygdrive/c/Tcl/bin:/cygdrive/c/Windows/system32:/c
ygdrive/c/Windows:/cygdrive/c/Windows/System32/Wbem:/home/Administrator/NS2/ns-a
llinone-2.35-RC3/ns-2.35:/home/Administrator/NS2/ns-allinone-2.35-RC3/nam-1.15
Now at least the path to NAM seems to be correct but I still can't access
NS and NAM outside their directories.any suggestion?
Thanks,
Mobin
