How to solve [version conflict for package "Tcl"]

anasnet · 10-15-2011, 05:40 PM

I have installed Ns-2.34 on Ubuntu 11.10, but when I tried to run

$ ns example1a.tcl

i got

nam:
[code omitted because of length]
: version conflict for package "Tcl": have 8.5.10, need exactly 8.4
while executing
"package require -exact Tcl 8.4"

Can you please help me to solve this problem

gns 3 0.7.4-1 is available in the Ubuntu repositories.

Thank you for your quick reply, but I'm new for unix, how can I install gns 3 0.7.4-1???

In Ubuntu, run Ubuntu Software Center from the left panel, then type gns into the search box at the top right. Click more info, then Use this source. Click the button with the arrows in a circle to refresh, then click install.

GNS 3 is a special simulator for Cisco files only.
Ns-2.34 is an "ns2 simulator". http://isi.edu/nsnam/ns/

Tcl issues : No tcl8.x-dev etc. should be installed at ns2 build time.
Please uninstall tcl, tk : sudo apt-get remove tcl8.5 tk8.5

.. And then start from scratch with ns-allinone-2.34 :
cd ns-allinone-2.34/ && ./install

P.S. : Ubuntu 11.10 is probably the worst choice for ns2.
Any other OS will make things easier. (Except 11.04 64bits.)

Thank you a lot for your response, I would like to ask you what version of ubuntu do you think is better for installing Ns-2??

The long term supported version Ubuntu 10.04 should be preferred : 32bits.

Any 64bits OS provides a reduced result.

Nam issues ? Use a binary 'nam'.
32bits https://docs.google.com/uc?id=0B7S25...nload&hl=en_US
64bits https://docs.google.com/uc?id=0B7S25...nload&hl=en_US

Unpack nam-1.14-<arch>.tar.gz, and : sudo cp nam /usr/local/bin/
