I don't update the Cygwin binary available at the wiki very often. This is
because I don't have much time available and it ties up the machine I have quite
a bit. I am attempting a build right now for 4.6. At one time we add one of
our maintainers doing a regular mingw build with its own windows setup program.
He is no longer available to provide this. We are looking for a volunteer to
do these, but the original scripts seem to be lost and no one has stepped up.

I will post the Cygwin build update if/when successful.

Regards,

Jerry

Thx for your responses, Fernando.

I'm trying to document how to use gfortran on windows while I've still
got it all fresh in my head. I use windows for fewer and fewer things
anymore, and before I put it on mothballs entirely, I want to be able to
have this capability squared away as a back-up.

I'll take a look at that link for the sake of thoroughness. Do you like
your install?

So I'm hoping with this thread to describe what I think would be a good
update for the fortran wiki. In doing so, I intend to honor the wiki
convention of putting some work into it to see what's out there, and how
a person is best informed.

I learn mainly by my eyes. When my 44-yr old, desert, allergy and
construction-irritated eyes comes onto new places on the net, I need to
see maybe more trailmarkers than others. In real life, I rely on geoff,
who was up four skins in the front 9 and ended the day even with the old
man who couldn't even putt.

So my first question is what you're supposed to do when you go through
mingw. Are you supposed to end up here, and download this thing?

***

What I would offer is a simple windows tutorial. Even with this limited
ambition, I think there would have to be changes to the 2 following links:

http://gcc.gnu.org/wiki/GFortranBinaries

http://gcc.gnu.org/wiki/GFortranBinariesWindows

I would expect there to be many opinions on this, but I assume that the
gfortan folks can basically send me the same signals on this. I think
you guys need a documentor as much as your documentation does.

***

This is where I would deviate from defaults and for good reason.
'Program Files' sucks on a command line. Simple and plain. 'gcc': better.

Beautiful night here is the desert southwest. Cicadas still going.
Gib, the other thing about cicadas is that they do the "tick tick tick"
like a Predator.

I went for a mingw install and failed spectacularly:

If you gfortran folk will not come to terms with this, I will start
taking it out on the pandas. Tug McGraw ++.

Hi Uno,

As a matter of fact, I'm a plain Windows user, since I learn,
research, and teach, using Linux. I use development tools in Windows
only when strictly required (and I have to recognize that "strictly"
have several different meanings along the time...). That said, I
installed gfortran via tdm-gcc and it worked immediately ok, and this
implies I really like it. I'm pretty much sure I had some trouble with
other options, but I don't remember the details, maybe having to
rename directories was one of them (an ugly one, for me). By the way,
I've installed Code::Blocks in Windows because some student asked for
a Windows IDE for making some programs using sockets, and I found
Code::Blocks fine, I've finally made some examples for sockets,
fortran, and OpenMP under Windows (all in different times, for
different people).

I'm still a plain user, who did some little example programs in
Windows, I don't know similarities/differences among the different
options for Fortran compilers and IDEs in Windows, just as an example
of my ignorance.

Hope this helps,

Fernando.
