4.1 GNU Compiler Collection

The GNU Compiler Collection (GCC) consists of utilities that you can use to compile programs, written in languages that include C, C++, Objective-C, Objective-C++, and Fortran. The GCC provides compilers such as gcc and g++, run-time libraries such as libgcc, libstdc++, and libgfortran, together with other useful tools.
