The GNU Compiler Collection (GCC) is a compiler system produced by the GNU Project supporting various programming languages. GCC is a key component of the GNU toolchain. The Free Software Foundation (FSF) distributes GCC under the GNU General Public License (GNU GPL). GCC has played an important role in the growth of free software, as both a tool and an example.

Originally named the GNU C Compiler, when it only handled the C programming language, GCC 1.0 was released in 1987. It was extended to compile C++ in December of that year (the default support in the current version is gnu++14, a superset of C++14 (or gnu11 a superset of C11) with strict standard support also available, and experimental C++17 and later). Front ends were later developed for Objective-C, Objective-C++, Fortran, Java, Ada, and Go among others.

“Version 4.5 of the OpenMP specification is now supported in the C and C++ compilers” and “a much improved implementation of the OpenACC 2.0a specification” is also supported.

GCC has been ported to a wide variety of processor architectures, and is widely deployed as a tool in the development of both free and proprietary software. GCC is also available for most embedded systems,[citation needed] including ARM-based; AMCC, and Freescale Power Architecture-based chips. The compiler can target a wide variety of platforms.

As well as being the official compiler of the GNU operating system, GCC has been adopted as the standard compiler by many other modern Unix-like computer operating systems, including Linux and the BSD family, although FreeBSD and OS X have moved to the LLVM system. Versions are also available for Microsoft Windows and other operating systems; GCC can compile code for Android and iOS.

Git is a version control system that is used for software development and other version control tasks. As a distributed revision control system it is aimed at speed, data integrity, and support for distributed, non-linear workflows. Git is easy to learn and has a tiny footprint with lightning fast performance. It outclasses SCM tools like Subversion, CVS, Perforce, and ClearCase with features like cheap local branching, convenient staging areas, and multiple workflows.

To learn more about using git, please refer to its homepage: https://www.git-scm.com/, you will find many ressources there.


GitHub is a web-based Git repository hosting service. It offers all of the distributed version control and source code management (SCM) functionality of Git as well as adding its own features. It provides access control and several collaboration features such as bug tracking, feature requests, task management, and wikis for every project.

GitHub offers both plans for private repositories, and free accounts which are commonly used to host open-source software projects. As of April 2016, GitHub reports having more than 14 million users and more than 35 million repositories, making it the largest host of source code in the world.

The trademark mascot of GitHub is Octocat, an anthropomorphized cat with cephalopod limbs, portrayed in a manga style.

LizardFS uses Github for its source code repository and bug reporting location.
