sudo apt-get install tcl8.5-dev tk8.5-dev

Question

I want to install ns2.35 on Ubuntu 14.04. When I implement this command:

$ sudo apt-get install tcl8.5-dev tk8.5-dev
Reading package lists... Done
Building dependency tree  
Reading state information... Done

E: Couldn't find any package by regex 'tcl8.5-dev'
E: Unable to locate package tk8.5-dev

A tip, you can search for any package for any release version of Ubuntu in this website, and also you can download the files from that site, here are the two packages that you're trying to install:

• tcl8.5-dev (8.5.15-2ubuntu1)
• tk8.5-dev (8.5.15-2ubuntu3)

Once downloaded the .DEB files, to install them, just follow these steps:

• Assuming the .DEB files are for am64 and are located in ~/Downloads:

  cd ~/Downloads
  sudo dpkg -i tcl8.5-dev_8.5.15-2ubuntu1_amd64.deb
  sudo dpkg -i tk8.5-dev_8.5.15-2ubuntu3_amd64.deb
  

But I believe you're going to need some dependencies for those 2 packages to be installed correctly and work, you can check the output of my terminal at the beginning.

Those packages exist; check your sources.

I have downloaded package tcl8.5-dev and package tk8.5-dev but I don't know how can I install them. I am a new user of Ubuntu.

@lafille you can install *.deb files by sudo dpkg -i file.deb or sudo dpkg -i /location/file.deb

@ChaiT.Rex: Tcl and Tk are in the main pocket in Trusty.
