and you should now get a 'nam' that works. _ _ _

sorry to bother you sir,
where do I run './install' ?
in home/jeffrey/ns-allinone-2.33/tk-8.4.18 ?
or
in home/jeffrey ?

thank you

Post # 16, @helok : I think you already know where to run ./install
.. that's in the top directory, i.e. home/jeffrey/ns-allinone-2.33/.

AFAIK, you already have a 'nam' version 1.14 in /usr/local/bin/,
and you only need one nam for all versions of ns2.

Please read the above posts # 12 and # 14.

Hello Sir,

I installed ns2.29 on Fedora 12. Unfortunately, NAM doesn't work.
I got same error. moreover, when I tried to download patch file, it doesn't work.
Could you please help me and send me a patch file and steps to implement it as well.

Thank you in advance and your help is appreciated.

# 20

Better : Use the more advanced nam-1.14, post #4 here ..
http://www.linuxquestions.org/questi...04-a-842109/#4
I.e. : # cp nam /usr/local/bin/

If you anyway want to fix an old nam, the tk-8.4-lastevent.patch is here
ftp://ftp.swin.edu.au/gentoo-portage...astevent.patch

I guess you mean "How to achieve a working 'xgraph' ?
The answer is : $ sudo apt-get install xgraph
... If your OS isn't Debian / Ubuntu / Mint, please specify your OS :
a) $ uname -m
b) $ cat /etc/*release*

Hi,
after the installation ns2.31 on fedora12, i had this same problem of nam (in the last line bind Li), to correct it i used the method of the patch. i downloaded the tk-8.4-lastevent.patch and i put it on tk-8.4.14 folder.

then i did this:

cd ns-allinone-2.33/tk-8.4.14/
patch -p0 < tk-8.4-lastevent.patch

and i ran ./install again.

after this i called the nam by nam command in the terminal, and i had this error:

Quote:

-bash:nam: command not found

how can i solve it, please?

knudfl · 11-21-2015, 03:47 PM

Re #24.

First : Check if you created a usable nam : cd nam-1.14/ && ./nam
If nam is working : # make install
( 'make install' will copy 'nam' to /usr/local/bin/
... just like # cd ns-2.33/ && make install will copy 'ns' to /usr/local/bin/.
Therefore : No *PATH settings are required. No adding no *PATH to .bashrc ).

Else : Install a nam package. Much easier than a build. Is what most people do :

Download an el6 package for your architecture, i686 or x86_64.
i686 https://drive.google.com/file/d/0B7S...ew?usp=sharing
x86_64 https://drive.google.com/file/d/0B7S...ew?usp=sharing

And : # cd Downloads/ && yum install nam-1.14-*

Ok thank you, nam works now after using make install.

please, about the .bashrc file, when i am installing the ns2 after the ./install, it asked me to add path in .bashrc file, so i did it.

now when i added the patch of the nam(lastevent.patch) i did install agin so it asked me to add the path again while the path already exists.

This is my .bashcr file:

Quote:

.bashrc

# Source global definitions
if [ -f /etc/bashrc ]; then
. /etc/bashrc
fi

# User specific aliases and functions
PATH=$PATH:/home/marwa/ns-allinone-2.31/bin:/home/marwa/ns-allinone-2.31/tcl8.4.14/unix:/home/marwa/ns-allinone-2.31/tk8.4.14/unix
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/home/marwa/ns-allinone-2.31/otcl-1.13:/home/marwa/ns-allinone-2.31/lib
export TCL_LIBRARY=$TCL_LIBRARY:/home/marwa/ns-allinone-2.31/tcl8.4.14/library
~
~
~
~
~
~
~
~
~
~
"home/marwa/.bashrc" 11L, 450C

since you told me that i must not add path, so what i understand that i must delete those lines:

Quote:

PATH=$PATH:/home/marwa/ns-allinone-2.31/bin:/home/marwa/ns-allinone-2.31/tcl8.4.14/unix:/home/marwa/ns-allinone-2.31/tk8.4.14/unix
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/home/marwa/ns-allinone-2.31/otcl-1.13:/home/marwa/ns-allinone-2.31/lib
export TCL_LIBRARY=$TCL_LIBRARY:/home/marwa/ns-allinone-2.31/tcl8.4.14/library

then i must do source .bashrc or something else or only delete them?

Thank you so much.

No. You are not asked to add any *PATH text to .bashrc .
It's just a ~15 year old text from those days when students used a University Computer.
The executable 'ns' or "ns-<any-name>" is hard coded to know the location of it`s libraries:
ns-allinone-2.3x/{ lib/*/*, bin/tcsh8* }. And 'nam' is partly statically compiled.
You can actually run 'nam' OK on a computer with no ns2 and no {tcl8*, tk8*}.

".bashrc" is a text file : Easy to edit.
Just select : View > Show Hidden Files in Nautilus / Konqueror.

The original .bashrc :

Code:

# .bashrc

# Source global definitions
if [ -f /etc/bashrc ]; then
	. /etc/bashrc
fi

# User specific aliases and functions

marwa88 · 11-21-2015, 05:41 PM

when i say it asked me to add path i mean this message tha appears at the end of ./install

Quote:

Please put /home/marwa/ns-allinone-2.31/bin:/home/marwa/ns-allinone-2.31/tcl8.4.14/unix:/home/marwa/ns-allinone-2.31/tk8.4.14/unix
into your PATH environment; so that you'll be able to run itm/tclsh/wish/xgraph.

IMPORTANT NOTICES:

(1) You MUST put /home/marwa/ns-allinone-2.31/otcl-1.13, /home/marwa/ns-allinone-2.31/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/marwa/ns-allinone-2.31/tcl8.4.14/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-2.31; ./validate

sorry for asking again, but what i need now is only to remove the path from the .bashcr file? then i run this command again or not
"source .bashrc" ?

thank you.

Re #28 , the last century text, ~1999 ...
Please put .... ,, IMPORTANT NOTICES: You MUST put ..
.. was meant only for a "University Computer" :
.. i.e. when you had no write permissions to /usr/local/ : No # make install .

NS-2 is old. A lot of files still have leftover from the ninetieth.
So don't believe everything you read in the files or on the Internet.

$ source .bashrc
... is for adding stuff. Editing :
$ gedit .bashrc
.... ( Or whatever editor you prefer.)

marwa88 · 11-22-2015, 10:15 AM

Thank you for the explanation.

I thought that the commande source is necessary after any modification in the .bashrc file ( i mean for the changes to take effect) .
So it is sufficient to do gedit .bashrc and save the file.

Thank you again.
