Fortran Compilers and Links
RISC-OS Fortran Compilers and Links
We know of 3 Fortran77 compilers which run under RISC-OS:
- Acornsoft's Release 2 Fortran77 compiler
- Free GNUf77. Click here
to download the latest RISC-OS version.
This version is also available on the Foundation RISC User issue 6.
- The Norcroft Fortran Compiler, written by the people who wrote
the Acorn 'C' compiler, but it lacks a debugger and has not been marketed.
Release 2 Fortran77 compiler
Acorn's Fortran77 (release 2) compiler can be bought from:
P.O.Box 80, Eastleigh, Hants SO5 5YX, UK
tel: (01703) 261514 fax: (01703) 267904
They also market our windows based ‘Fortran Development
Environment’ which allows compilation, linking and execution from the
An explanation of how it works can be seen here.
An updated version (4.33 27 Sep 99) is now available for
RISCOS 4 which
allows long filenames and more than 77 files in a directory. It will run
with RISCOS 2 and 3, but has few improvements over the previous version.
Get it from the supplier
by returning your original Desktop Fortran
distribution disc and a cheque payable to ‘K.M.Crennell’
for £5.88 (includes all packing, postage and VAT charges).

GNU Fortran 77 This comes from the
Free Software Foundation Inc,
59 Temple Place, Suite 3330, Boston, Mass, 02111-1307, USA
to find how to download your free compiler.
We are collecting further information and a
list of bugs to give to the implementers.
Other Fortran related sites
General information about Fortran and libraries can be found
- in the UK at :
- The Computer Physics
Communications Web site has many lists of physics related software
- The Numerical Algorithms Group
NAg site which
has some Public Domain code.
- Netlib - a repository of mathematical software, data etc.
- The Harwell Subroutine Library:
If you are a UK academic, you are now able to
versions of library packages, without charge, for academic purposes.
Details from: Hsl@hyprotech.com
In addition, older HSL packages are now available in the
without charge to anyone for non-commercial exploitation.
- in Europe there is a
- in the USA at :
- Mathtools site had useful
libraries, routines and information of compilers etc.
It is now no loner maintained but has some useful links.
- Unit conversions
facilitates many useful everyday numerical conversions

Join us in lobbying RISCOS Ltd
to provide better Fortran support, in particular:
- a Fortran90/95 compiler
- an optimised Fortran compiler
- a Fortran compiler which obeys the APCS for cross calling routines written in C
- a file type for Fortran Source code
