Introduction

The GNU Compiler Collection (usually shortened to GCC) is a compiler system produced by the GNU Project supporting various programming languages. GCC has been adopted as the standard compiler by most modern Unix-like computer operating systems with GNU/Linux. GCC has been ported to a wide variety of processor architectures, and is widely deployed as a tool in commercial, proprietary and closed source software development environments.

Vendor : GNU Compiler Collection.

Architecture : x86_64

Release : 4.1.2

3. Java – (gcj) and

4. Fortran (gfortran) .
