[netCDF #MPL-618419]: Problem building in cygwin.

see if there's a 'donations' link.  I must admit, I've never done that before
with gpl or open source software, and although I'm sure you have a decent
income source for this, I truly think you guys are great and clearly deserve
something in return

Thanks for the kind words!

As for the offer of donations, the National Science Foundation has got it
covered for you. However, you are already contributing to netCDF: your
experiences with netCDF will improve our documentation or distribution, because
when I figure out what the heck is going on with your code I will make sure it
doesn't happen again to someone else. ;-)

I was hopeful it would work.  It has the same complaint. I've looked at it and
have a clearer idea aobut what's happening so, hopefully, I can explain it
better. I think the cleanest way to explain this is to show you the libraries
it built in

messages are refering to.

directory and, I *think* - but I'm not used to this syntax - it tries to merge
the contents of /fortran/.lib/libnetcdff90.a (or perhaps create it) with
content from the library of the same name under the f90 directory.  Because I
don't know this syntax, I admittedly find this very confusing, although it may
look obvious to some of you. (If not, you should have one of your
script/makefile experts take a look at this.)

We use autoconf/automake/libtool to allow netcdf to build and test on a very
wide variety of platforms. In general it is not worthwhile to spend too much
time figuring out what it is trying to do in individual cases. There's a lot of
weird crap going on, but that's OK, because it's not *my* weird crap.

However this should work, since I build on cygwin every night and it is a very
well behaved platform. I need you to send me the complete output of configure
and make check, and also the config.log. Yes, this is a lot of text, but that's
OK. Just paste it in the body of your email and send it to me, and I will see
if I can figure out what is going on.

Unfortunately, no attachment - did you forget?

I need the output of configure and make check as well. If you didn't save it,
just do a "make distclean" and start over, saving all the output.

Thanks,

Ed
