Free/commercial windows Fortran compilers

[anal...@hotmail.com]

I am very happy with my home copy of Lahey compiler, but apparently
they are not going to gurantee compatibility with Windows past Windows
XP.

I need a Fortran compiler for profesional use and up to $1000 can be
spent fo it. Would the Intel compiler be the best bet in this case?

Thansk for all inputs.

I'm very happy with the Intel compiler.

PGI Fortran is also a good choise.

I am very happy with g95 and I am sure that Andy would be glad
to receive you $1000. Imagine the amount of beer he can order
at his local microbrewery! I find g95 very good in feedback during
development phase. Somehow, the Portland compiler (PGF) manages
to make faster executables, but I find their compiler too
sloppy in accepting code with small errors. But once it runs,
your code will be fast. Ifort works fine. With gfortran I have to
make up for the recent developments. Some years ago my code was
rejected by gfortran and then I continued with g95, but
today gfortran eats my code.

What would you be using the compiler for?

Free compilers, Windows:
g95
gfortran (seems to now have a performance edge over g95)
Salford/Silverfrost FTN95 (poor performance, lovely IDE, wonderful
support for catching run-time errors.)

I'd recommend FTN95 for development support. If you plan to use it other
than as a hobbyist then you should buy your FTN95 copy. My favourite
IDE.

Watcom. Fortran 77 only. The development work for this project appears
to be on the C++ side, with Fortran being supported just to keep it
binary compatible for object files & libraries. Clunky editor; I
switched to an alternate (DOS-based editor) and compiled at the
command line. Last time I looked the editor hadn't progressed. If you
like VI then I think you'll get on well with the editor.

Commercial:
Intel - always highly recommended
Absoft - I haven't used in years, but it looks as if they have become
much better - the IDE used to be clumsy compared to the
competitors. Their strength was that you got a C++ compiler
bundled with the Fortran compiled, a great help if you had to
support mixed-language systems.
PGI/Lahey/NAg/anyone else - no comment, as I have never had exposure to
them.

prototyping data analysis type code. Luckily there is no anti-Fortran
bias where I'll be doing it - so it might go into production also.

The amount of data involved might be large (1 GB say). No serious
"number crunching" as tradion ascribes to Fortran. Just need to be
able to write legible, reasonably fast code to summarize large amounts
of transactional data.

I'd begin the selection process by browsing Polyhedron's Fortran
comparisons: http://www.polyhedron.com/compare0html

Hi

The problem with the 7.1 Pro compiler is that it includes Visual Studio
2003, which is not supported on Vista. The new 7.2 Pro compiler
includes a VS2008 shell and works fine on Vista and Windows 7 RC1 (32
and 64 bit). None of this is an issue with the Express compiler.

Well, Thats good to know - but I'll probably end up making the "safe"
bet and go with Intel. I guess I can expect my home copy to be
upgraded if and when I get a new box.

Thanks for everybody's inputs.
