4. Free Compilers: GNU Compilers and F

There are a small number of free Fortran compilers available.

4.1. GCC

The GNU Compiler Collection (GCC), which is installed on Cosmos and is available for Solaris, Linux and most other platforms (including Microsoft Windows), includes a Fortran 77 compiler, g77. To run the compiler simply type

g77 <source_file>

at the command line. The full path is /usr/local/bin/g77; its use should not be necessary as /usr/local/bin/ will be on your path by default.

The GNU homepage for Fortran is on the GNU site at /software/fortran/; full documentation is available on-line via that page, or directly via the gcc.gnu.org site at /onlinedocs/g77_toc.html

ISD offers no support for this compiler other than this documentation.

4.2. F

GNU do not yet have a Fortran 90/95 compiler available, though there is one "in progress". However you might like to know about F, a subset of Fortran 90 --- the 77-"baggage" has been removed --- a language for which free compilers are available. The F homepage may be found via swcp.com/~walt.

We offer no support for F.
