GCC (Compiler)

GCC is a collection of compilers which share a unified middle/back-end. It generates generally good code, but is NOT the recommended compiler for SHARCNET systems and is provided and intended only for experimental and evaluation purposes. Included in this installation is gcc, g++ and gfortran which can be accessed by following usage instructions on the Wiki documentation page linked below. In addition to the GCC versions available via modules listed below, each system has its own built-in, default GCC compiler.
