Hello,

I am new to Fortran and am wondering if their are any compilers for
Mac OS X? I know specifics on my intended use would be wanted by any
answerers, but I have none. Basically I've read that it still beats
the other languages for number crunching, which caught my interest.
Therefore I'm just looking for a compiler so I can play around with
Fortran to see if I like the language. My previous experiences with
programming are Java, C, and a little assembly. I've done some
examination of the syntax and I like what I see. However, one can't
know if they really like using a language until they, well...use it.
Any help would be appreciated. Thank you.

There are several commercial compilers. NAG, Absoft and Intel are the
usual suspects. This crowd offers their product for Windows and Linux as well.
GNU comes in Gfortran and G95 flavors for multiple platforms.

If you are new to Fortran you will particularly interested in debugging.
NAG has the best as they are the only ones to provide full undefined variable
checking. The real McCoy of run time checking and not the check box imitator
of reporting the absence of any initialization. All provide subscript checking.

The standard Mac development environment is XCode, which comes with the
standard upgrade disks, and is available at their site. It is gcc 4.2
based. Because Apple disagrees with some of the provisions in the GPL
licence that applies to later versions of gcc, they have no plans to
upgrade to later versions of gcc. It does not come with a version of
fortran, but older versions of gfortran can be installed to work with
that version. I suspect the same can be said for g95, and that the
commerical compilers will automatically work. Newer versions of
gfortran, and probably g95, require a separate installation of a
comparable version of gcc. Later versions of gcc, which come with
gfortran, are available through MacPorts, http://www.macports.org/.

I have the latest version of g95 installed on this OS X 10.6 system. I
don't recall having installed anything special for it other than the
regular Xcode stuff. I certainly didn't do a separate gcc install; it is
a new enough system (27" iMac, ordered as a "birthday present" for
myself as that's the day they came out) that I'd have remembered
something like that.

Might be that the g95 install included whatever gcc stuff was needed.
Sort of looks like that, in fact. But I didn't dig in detail. I just
note that I did not need to separately install anything else (except for
the normal XCode stuff.)
