Hello All,

I have encounter problem when I do as follow in unbuntu 10.0.4.kmw@ubuntu:~$ ns
application-specific initialization failed: Can't find a usable init.tcl in the following directories:
/home/kmw/ns-allinone-2.34/tcl8.4.18/library:/usr/lib /home/kmw/ns-allinone-2.34/lib/tcl8.4 /home/kmw/ns-allinone-2.34/tcl8.4.18/library:/usr/lib /home/kmw/ns-allinone-2.34/tcl8.4.18/library:/usr/tcl8.4 /usr/local/lib/tcl8.4 /usr/lib/tcl8.4 /usr/local/library /usr/library /usr/tcl8.4.18/library /tcl8.4.18/library /home/kmw/ns-allinone-2.34/lib/tcl8.4
This probably means that Tcl wasn't installed properly.
% .

So,please help me !
It is important for me.

This error can happen if you make any changes to the "ns-allinone-2.34/" directory :
Renaming the directory, moving the directory to another location,
i.e. anything that will change the "/home/kmw/ns-allinone-2.34/tcl8.4.18/lib/" path.
Or when changes were made in /home/kmw/ns-allinone-2.34/tcl8.4.18/lib/
Note :
The binary 'ns' is hard coded to know the location of it's libraries, tclsh8* :
/home/kmw/ns-allinone-2.34/tcl8.4.18/bin/, /home/kmw/ns-allinone-2.34/tcl8.4.18/lib/

Workarounds, fixes :
1) cd ns-allinone-2.34/tcl8.4.18/ && ln -s lib/ library
2) Reinstall ns-allinone-2.34

Hello sir,
Thank You for your quickly reply!
You always save me!

I faced the same problem during my last installation of ns2.35 in ubuntu 11.04.
After I install ns2.35, got message of successful installation of ns. Then I set path in /.bashrc. Then I gave ns command which gave me same error which you got.

The problem is because, ns executable is also at /usr which is conflicting.

Solution:
1. Go to location root-usr-local-bin by giving following command in terminal
cd /usr/local/bin
2. There you would find the ns file. We just need to remove it by giving following command
rm ns
3. Thats it, you are done. Now your ns starts running successfully.

Happy Learning.....

Dear Sir,
I make changes ns2 directores and reinstall again when I can't solve the error e.g Link State.0. I occur that error whenever i change .tcl and .cc and Makefile.in under ns directory. last time reinstallation is ok,(just delete the old ns2 directory and create new folder and place new installation in it. but now, I have "Can't find a usable init.tcl in the following directories:" Error. As you mention, I use this command "cd st/ns-allinone-2.35/tcl8.5.10/ && ln -s lib/library" , then this following error occurs "ln: failed to create symbolic link `./library': File exists". How to fix this , Sir. Please kindly help me.

Regards,
Ms. Nwe Nwe

Please check are you logged in as super user?
Type in command prompt,
sudo su
Permission is denied because u r not logged into as super user.
Once logged into as super user, u would be able to follow the procedure.

Post # 6.

ns-allinone-2.xx cannot be renamed or moved to a new folder.
Then 'ns' will not find ns-allinone-2.xx/lib/, ns-allinone-2.xx/bin/.

And : ns-allinone-2.35 is particular problematic.

@knudfl, @bhargavigoswami

Thank you very much both of you Sir. Now, I solved that Problem.

Dear All,

Have you got any idea on data storage on mobile nodes of MANETs? I wanna store user data on the mobile nodes and want to share that data among the nodes. Is it possible to implement in NS2? Although I've been digging up the Internet about this problem , I can't find it out yet. If you have knowledge on it, please kindly tell me the links or some tutorials. Thank you in advance.

Regards,
Ms. Nwe Nwe

# 10 .

If at all possible ( I have no idea what it is about ),
there are better chances with the more complex simulators.
NCTUns / EstiNet, OMNeT++, ns3 :
I guess they all have a Forum, where you can ask.

tcl not initailased issue after installing ns2.35 on ubuntu 16.04

Post #12, @deepika2210 : Welcome to LQ.

ns-2.35 and Ubuntu 16.04 :
And please do not run `./configure && make´ in ns-2.35/ :
Use the `$ ./install´ command in ns-allinone-2.35/ → →
The 'install' script takes care of all configure && make, in the right sequence.
