moving from g77 to a more modern compiler.

Hello.

I'm playing with g77 for a (very) long time, but from some rumours,
it's an obsolete compiler. I'm on Linux and OpenBSD platforms, and
s

ing for a more modern and "libre" alternative for g77, with
an option who warn me when I do "no ethic 77 programming".

No troll, please, because I said "playing" :)

Look for gfortran or g95. The former is part of gcc 4.x.

Some widely distributed versions of both are already obsolete. Avoid gcc
4.0, in particular.

I have had good results with gfortran 4.2. It can pretty much compile all
your fortran 77 code. gfortran also works with Fortran 90/95. AFAIK g77 is
no longer supported. So, IMHO, you should shift to a latest compiler.

If you intend to stick with Fortran 77, you can also use OpenWatcom. I
think that one is still supported.

Since Fortran 77 is a subset of Fortran 95 (except for some minor
exceptions which nearly all compilers implement as extensions), just
about any modern supported Fortran compiler will compile Fortran 77 code.

What they won't do is warn when you use something that's in Fortran 95
but not in Fortran 77, in many cases.

Ok, thanks to all. I'm going on the way to gfortran.

Have a good night/day.
