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 and the standard compiler for most Unix-like Operating Systems. 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. 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. By default, the current version supports gnu++14, a superset of C++14 and gnu11, a superset of C11, with strict standard support also available. It also provides experimental support for C++17 and later.
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, including ARM-based; AMCC, and Freescale Power Architecture-based chips. The compiler can target a wide variety of platforms.
