Open a Terminal, and enter ' gcc -version'. It is the standard compiler for most Unix-like operating systems. GNU Toolchain, including GCC, is included in all Unixes.

-std=c++2a, or -std=gnu++2a (C++2a with GNU extensions), experimental.-std=c++17, or -std=gnu++17 (C++17 with GNU extensions), experimental.-std=c++14, or -std=gnu++14 (C++14 with GNU extensions), default mode for GCC 6.1 and above.You can use command-line flag -std to explicitly specify the C++ standard. The default mode is C++98 for GCC versions prior to 6.1, and C++14 for GCC 6.1 and above. GCC version 3 (2001): incorporating ECGS (Experimental GNU Compiler System), with improve optimization.GCC version 1 (1987): Initial version that support C.GCC is also a cross-compiler, for producing executables on different platform. They are also ported to Windows (by Cygwin, MinGW and MinGW-W64). GCC (and GNU Toolchain) is currently available on all Unixes. GCC is portable and run in many operating platforms. GNU Bison: a parser generator (similar to lex and yacc).

GNU Autotools: A build system including Autoconf, Autoheader, Automake and Libtool.GNU Binutils: a suite of binary utility tools, including linker and assembler.GNU Make: an automation tool for compiling and building applications.GNU Compiler Collection (GCC): a compiler suite that supports many languages, such as C/C++ and Objective-C/C++.GCC is a key component of so-called ' GNU Toolchain', for developing applications and writing operating systems. The current version is GCC 7.3, released on. It is now referred to as ' GNU Compiler Collection'. GCC, formerly for ' GNU C Compiler', has grown over times to support many languages such as C ( gcc), C++ ( g++), Objective-C, Objective-C++, Java ( gcj), Fortran ( gfortran), Ada ( gnat), Go ( gccgo), OpenMP, Cilk Plus, and OpenAcc.

Richard Stallman founded the GNU project in 1984 to create a complete Unix-like operating system as free software, to promote freedom and cooperation among computer users and programmers. The original GNU C Compiler (GCC) is developed by Richard Stallman, the founder of the GNU Project. GCC (GNU Compiler Collection) A Brief History and Introduction to GCC
