Hi
i ve installed ns2.35 in ubantu14.04,
i hav successfully run tcl script, bt when i've tried to execute nam command, it gave me " Segmentation fault (core dump)" .
although i can sucessfully run awk & Xgraph commands, bt unable to run nam
plz help me out...

Segmentation fault = memory fault. It probably tried to access a page of memory that didn't exist. Usually a dud software package.

Check all dependencies are present; run 'ldd /path/to/nam |grep found' (remove quotes and fill in /path/to)
There should be no output. Then reinstall it - it could be a poor download. Post back telling us how each thing worked out.

Welcome to LQ.

The 'nam' that you can build from ns2 (ns235) often fails.
And the Ubuntu nam that you can install with $ sudo apt-get install nam ,
... has not been OK for some time.

Example, "the perfect nam" : nam_1.15-10-ubuntu14_amd64.deb
→ https://drive.google.com/file/d/0B7S...it?usp=sharing

Which version is your Ubuntu 14.04 ? i686 or x86_64 ?
This command will show : $ uname -m

plz reply with appropriate solution

Which version of Ubuntu 14.04 are you using ? i686 or x86_64 ?
* This command will tell : $ uname -m

? What happens, when you type the nam command by itself : $ nam

* If it is an "out.nam" file that fails, like $ nam out.nam
.. then you will have to attach the file that creates "out.nam".
File.tcl must be attached as file.tcl.txt .

i m using i686

& when i simply run $:nam

it give segmentation fault (core dump)

← #6 .

When nam is run with no arguments, and shows "segmentation fault" :
a) Delete the nam-1.15/ folder and any other <nam-version>/ folder.
b) $ sudo apt-get remove nam

.. And please install the package nam-1.14-10_i386.deb

Hii ,

I have a similar issue..

when i try to run nam executable.. i get a segentation fault error.

I have followed the steps mentioned above and downloaded the nam_1.15-10*.deb file from the link mentioned above
but i am not sure of how to extract it and install it..

can you please peovide me the commands used to extarct the nam*.deb file and how to install the same.

Thanks and Regards,
Deepthi

Post #11, @eepthi18 : Welcome to LQ.

You don't extract a <package>.deb :
Click the package, and the `Package Intaller' will update
the faulty Ubuntu package to the new version nam_1.15-10 .

Hii,

Thanks for the quick reply..

I am new to unix n hence did not know how to install *.deb package.

I tried by installing by clicking on it,

i got some msg inbetween the installation, i have attached the doc regarding the same.

it did not show any msg like installation completed successfully, after some installation progress status, it went back to 1st screen of install.

I dont see any nam folders created in /usr/local/bin nor in my /home/deepthi/Documents/ns_allinone-2.35/ directories.
i am not sure if it is installed correctly..

when try to run the nam executable in terminal i get the below message

bash: /usr/local/bin/nam : No such file or directory

can you please suggest me on the same..

Installing a package manually :

$ cd <folder-with-package>/
$ sudo dpkg -i nam_1.15-10*.deb
