Setting up Cygwin to give you a complete compile environment looks
much harder than it is, but I agree that Cygwin's packaging
interface is not as intuitive as it should be.  Once you've gone
through their menus once and figured it out, it's not a big deal
from then on, but that first time is confusing.  Not much the Xastir
project can do about that one though.  It ain't ours.  We also
really appreciate having such a free C development environment
available which makes it so easy to port Unix/Linux apps to Windows.

You didn't convert your UI-View maps for use with Xastir?  I can't
recall now whether you tried that, but a lot of people are using
UI-View maps with Xastir, on all platforms.

Shouldn't be necessary.  There's a Perl script in the Xastir/scripts
directory that will write a .geo file for the .inf file, then you
can index the map in Xastir and you're off and running.  With a
small amount of work we could use UI-View maps directly in Xastir
without having to create the .geo file first.  We've just not
written the code to do that yet.

Running any TNC in command-mode is a tricky operation.  We don't
have a specific startup file for a TNC-220, so that's likely where
you ran into difficulty.  Had you put it in KISS mode or created a
command file specific to that model it should have worked well.
Should anyone write one for a TNC-220, send it to us and we'll add
it to the distribution.  Yet another way to contribute to the
project.

I recall having problems at times with certain Cygin installs, then
doing a Cygwin update a day or a week later and having all of the
problems cleaned up.  They change Cygwin often, sometimes breaking
things temporarily.  Luckily they don't usually break it for long.

Sounds like you have a stable version of Cygwin now, so perhaps
you'll give Xastir another try later.

I still recommend installing Xastir from sources.  It takes some
effort the first time around to set up the development environment,
but after that it's a breeze to update to the latest any time you
wish.
