configuring a gfortran capability on cygwin
Uno
windows xp on my dual-boot machine. So I thought I would try to
decrease the frequency of re-boots by filling out my capabilities on
both sides.
I was going along pretty good:

q1) What does this filesystem have to do with any other? Once I send
this, I'm gonna go take a look from the ubuntu side, and I'll know about
where it is in the filesystem, but how does cygwin "see out," if, for
example, it doesn't have 'media'?

So let me ask a better question. I found my thumbdrive under /cygdrive/e:
dan@tja1-d5768e2d16 ~
$ pwd
/home/dan
dan@tja1-d5768e2d16 ~
$ cd ..
dan@tja1-d5768e2d16 /home
$ cd ..
dan@tja1-d5768e2d16 /
$ ls
Cygwin.bat Thumbs.db cygdrive etc lib tmp var
Cygwin.ico bin dev home proc usr
dan@tja1-d5768e2d16 /
$ cd cygdrive/
dan@tja1-d5768e2d16 /cygdrive
$ ls
c e
dan@tja1-d5768e2d16 /cygdrive
$ cd e
...
$ cd gcc_eq32/
dan@tja1-d5768e2d16 /cygdrive/e/gcc_eq32
$ ls
Shortcut.bat echo lib run1.bat type
bin gcc-4.6-20100501-32.exe libexec share udtmod.mod
cls gfortran out source wtc1.f90

crude1.f90~ include p1.f90 tem2.c
da1.f90 jk3.f p2.f90 tobias1.f90
dir judy1.f90 p3.f90 tobias1.f90~
dan@tja1-d5768e2d16 /cygdrive/e/gcc_eq32
$ cd ..
dan@tja1-d5768e2d16 /cygdrive/e
$ cd fortran_stuff/
dan@tja1-d5768e2d16 /cygdrive/e/fortran_stuff
$ ls
b.f90 include p1.f90
bin jb1.f90 r1.f90

$
So I've got source there now, but not only do I not have gfortran, I
don't have ftp and any other thing I tried.
The one thing I wanted to make people aware of who are smarter than me
is that the gcc_eq32 was a 32-bit thing, while 'fortran_stuff' was 64-bit.
Thanks for your comment.

Do you have the NTFS driver for the linux side? That helps.
As far as I know, there is no Windows driver for any unix
file system.

dual boot systems and have had the most success
with mixing windows and suse linux.
the suse side can see ntfs windows disks
and generally can read and write ntfs
disks.
so a working practice i use is
boot windows
write fortran programs
reboot and start suse
mount disks and copy files over
i've never been able to 'see' linux
disks from a windows os that would enable me
to use files and directories.
i have not used ubuntu, as most linux software
i have to deal with supports redhat and suse.
the oracle/sun sunstudio fortran ide
and sun compiler works really well on suse linux.
i also tar files on the linux side and email
to myself and then use cygwin
on the windows side to extract stuff.
bit tedious i admit.
unix2dos and dos2unix are also life savers :-)
cheers

If you don't need graphics, just do everything in Cygwin. It is almost
exactly the same as using telnet to connect to a linux server. No
rebooting, no driver problems, no file system incompatibilities, and the
usual linux commands can be used without risk on your NTFS file system.
But perhaps only us old-timers can get by without graphics.

Yes; /cygdrive is the root of the Windows file system in cygwin;
your Windows-mounted drives appear there as the appropriate letter of the
alphabet.

Go to www.cygwin.com with your favourite browser
Right-click on the link to setup.exe; select "Save as..." and save
it in C:\cygwin
Exit the browser, open a Windows Explorer window and navigate to
C:\cygwin
Double-click on the setup.exe entry to run it
Keep clicking on "Next" to take all the default options
When you get to the mirror selection, choose one near you
At the "Select Packages" panel, click on "View" until ypu get to
"Category" view
Click the [+] next to "Devel" then scroll down until you get to
"gcc4-fortran" -- select it
At this point you may want to go to "View" category "All" and
select anything else you want, such as ftp
Click "Next" to install the selected packages (and any others that
need updating or are required for gfortran)
You now have gfortran:
Compaq_Owner@HomePC01 /cygdrive/c/ivan/words
$ gfortran --v
Using built-in specs.

compiling from cygwin to native Windows target) for both 32- and 64-bit
mode. For some purposes, I find the native 64-bit target mode
preferable to the 32-bit cygwin mode.
Caution: the mingw cross compilers are generally off topic on the
cygwin support mail list.

I've got my windows partition in media/ if I want to find it. I believe
that I have the capability that you allude to except that anything in my
pull-down menu for nautilus gives me my music player.
I figure that's the gnomes forcing me to use a terminal like a grown-up.
Alternatively, they just might like music more than my programming.
Let me ask you this question. How do I guery my *nix compliant system
to tell me where the files are that make compilation happen when I
invoke the gfortran compiler?

gfortran only looks for files in the current directory from which you
call it if relative or absolute paths to sources are not given.

I suppose I meant files like gfortran.exe and the libraries. Meanwhile,
I seem to be going backwards with cygwin:
dan@tja1-d5768e2d16 ~
$ ls -l
total 0
dan@tja1-d5768e2d16 ~
$
What do you do when root has no files?

If you've mucked up your cygwin installation, you could remove it,
preferably after reading the docs, and install again, including
selection of gcc4-fortran or your other preferred gfortran.
If you could get your act together and choose an appropriate forum among
the gcc-fortran, gcc-help, and cygwin lists, you might make faster
progress (most of it by reading the docs and preparing before asking
questions).

Thanks for your comment, Tim. Indeed, I did. There's a grab bag of
little differences between the commands of cygwin and *nix.

This is what I get, too.
So, following what Dr. Reid and Tim posted, I do now have a cygwin
fortran capability.

I did remove it, when I couldn't find anything under root and followed
Dr. Reid's recipe closely thereafter on rebuilding.

I'm definitely overdue to read through the cygwin stuff at least once.
I've never been able to use a mailing list fruitfully. Of course, I
only tried with gfortran and gcc, where I might be less than popular.
I wish there were a place on usenet where you can go and ask: is there a
group out there where this question ____ is topical. A search for
cygwin reveals this group: de.alt.comp.cygwin+co. While I can
communicate in german, the place just looks rather forlorn. I rarely
find useful ng's by searching for them with keywords.
