To install GCC (GNU's Compiler Collection) 

Debian / Ubuntu based Distributions can use the following commands to install the compiler collection to compile and run C/C++ programs.

sudo apt-get update
sudo apt-get install build-essential manpages-dev

In case, you are using Fedora, RedHat or CentOS, you can use the yum command to install it.

Linux Mint - from freedom came elegance.

Maybe I'm stating the obvious here - if so, forgive me.

As I see it, the only difficulty to using almost any distribution of Linux is in the setting-up stage. Once it has been installed and all software is in place, a user need not even be aware that it is Linux behind the applications he or she is using. We in this group are here because we are enthusiasts, to a greater or lesser extent - we enjoy getting to grips with the technicalities and moulding a system that suits us. And, of course, that is one of the keystones of the Linux movement (along with open-source and flexibility) but not everyone feels the same.

A few years ago, fired with zeal for the principles of Linux, and keen to get away from the suffocating hold that Microsoft has on the computing world, I started looking around for a distribution that was right for me. I crashed and burned. First I tried Red Hat, then various flavours of Ubuntu. Because I was completely new to Linux, I didn't understand how they worked, and the terminology was unfamiliar. I did get Ubuntu working, but found it, and the software bundled with it, crude (compared with the Windows stuff I was familiar with). 



Then, last year, I discovered Linux Mint. The beauty of Mint is that it makes the process of getting started much easier, and the resulting desktops are intuitive and attractive. The install process, for instance, which offers an automated installation to default settings, perfect for new users and technophobes (heck, it even installs all the most popular applications, and makes it easy to add many others). However, because it is Linux, it also has all the 'power' features that make Linux so popular.

So what I am saying here is that, in my opinion, Mint is changing the way Linux is perceived. It is no longer too complicated and esoteric for people who just want a computer that works for them. That is why I am such a fan - Mint is opening up Linux to the wider world.
