Compilers

GCC (GNU Compiler Collection)

"GCC (GNU Compiler Collection) is a set of compilers for various language (C, C++, Objective-C, Objective-C++, Fortran, Java and Ada) produced by the GNU Project."

gcc

GNU project C and C++ compiler. When used for C++ compilation, it internally calls g++ but it does not point all the standard C++ libraries. Make sure that you include -lstdc++ in this case. When GCC is compiled with Fortran language support, gcc recognizes Fortran source codes (.f, .for, .ftn, .f90, .f95 and .f03) and can compile them.<ref>http://gcc.gnu.org/onlinedocs/gfortran/GNU-Fortran-and-GCC.html#GNU-Fortran-and-GCC</ref>

g++

g++ (GNU C++) is a C++ compiler, part of GCC.

gfortran

gfortran is a Fortran compiler, part of GCC and still in the early stage of development. It will be expected to handle most Fortran codes written in Fortran 77, Fortran 90, Fortran 95 or Fortran 2003.<ref>http://gcc.gnu.org/onlinedocs/gfortran/About-GNU-Fortran.html#About-GNU-Fortran</ref>

g77

g77 is the ancestor of gfortran and was included in GCC prior to version 4.<ref> http://gcc.gnu.org/onlinedocs/gfortran/GNU-Fortran-and-G77.html#GNU-Fortran-and-G77 </ref>

Unix C/C++ Compilers

cc

Unix C compiler. In Linux, cc is a symbolic link to gcc.

CC

Sun C++ compiler

Intel Compilers

Intel compilers usually accelerate program speed. See WIKI

icc

Intel C/C++ compiler

ifort

Intel Fortran compiler

PGI Compilers

PGI compilers are Fortran and C/C++ compilers developed and provided by the Portland Group. The PGI compiler commands are pgf77, pgf90, pgf95, pgcc and pgCC. The Portlad group provides pdf form of the user guide.

pgf77

pgf77 is Fortran 77 compiler command. For quick help for the usage of swithes, type the following command at the shell prompt

$ pgf77 -help

pgf95

Fortran 90/95 compiler command.

pgf90

This command is identical with pgf95. It remains just for compatibility.

pgcc

C compiler command

pgCC

C++ compiler command
