I am totally new to Linux. All my studies are now dependent on it. So I've installed Ubuntu in my laptop. I need to install few software packages for my compiler course to run llvm (I am following the instructions from http://llvm.org/docs/GettingStarted.html). Following are the packages I need to install:

Package Version
GNU Make 3.79, 3.79.1; GCC >=4.7.0; python >=2.7; GNU M4 1.4; GNU Autoconf 2.60; GNU Automake 1.9.6; libtool 1.5.22; zlib >=1.2.3.4;

I will be using sudo apt-get install...............build-essential. Can anyone tell me what should I insert in the dot dot area to install all of the above? Also, do need to install Z and Zlibc? if yes, then what are their purposes?

I have tried to answer your question as it stands: however please read this first

How to install Ubuntu software when you're an ex-Windows user!

and seriously consider whether the instructions you are following are appropriate and necessary.

In general, you will need to use apt-cache (or browse the Software Center) - along with a little common sense. For example:

$ apt-cache policy m4
m4:
  Installed: 1.4.17-2ubuntu1
  Candidate: 1.4.17-2ubuntu1
  Version table:
 *** 1.4.17-2ubuntu1 0
        500 http://ca.archive.ubuntu.com/ubuntu/ trusty/main amd64 Packages
        100 /var/lib/dpkg/status

tells me that my system (Ubuntu 14.04) already has m4 version 4.17 (specifically, the Ubuntu build 1.4.17-2ubuntu1) and that it's already installed. If it wasn't already installed, then the package I would need to add to the apt-get command would simply be m4.

Sometimes, things are a little trickier. For example

$ apt-cache policy zlib
N: Unable to locate package zlib

in which case we need to do a bit of guesswork - let's try

$ apt-cache search devel | grep zlib
zlib1g-dbg - compression library - development
zlib1g-dev - compression library - development
libkaz-dev - Kazlib's reusable data structure development tools
gambas3-gb-compress-bzlib2 - Gambas bzlib2 component
gambas3-gb-compress-zlib - Gambas zlib compression component
gauche-zlib - zlib binding for Gauche
lua-zlib-dev - zlib development files for the Lua language

from which we might deduce that the actual primary zlib development package is probably zlib1g-dev; let's dig a little deeper

$ apt-cache show zlib1g-dev
Package: zlib1g-dev

OK - that indeed sounds like the thing we need - so what is its version in the repository?

$ apt-cache policy zlib1g-dev 
zlib1g-dev:
  Installed: 1:1.2.8.dfsg-1ubuntu1
  Candidate: 1:1.2.8.dfsg-1ubuntu1
  Version table:
 *** 1:1.2.8.dfsg-1ubuntu1 0
        500 http://ca.archive.ubuntu.com/ubuntu/ trusty/main amd64 Packages
        100 /var/lib/dpkg/status

i.e. version 1.2.8, again exceeding the minimum requirement (1.2.3.4) of the software you are trying to build.
