Odd, but ok.  :)

This is pretty odd.  It shouldn't even be looking for gnome-config.  Anybody 
know what samplerate is?  I remember there was some discussion about what 
resampling library to use about when I did the cygwin stuff, so it may be 
that Audacity switched to something else and cygwin is still expecting the 
older library.  To fix this, if this is indeed what's going on, you'll have 
to go into configure.in and change the part where the cygwin dependencies are 
handled.

What happened here is that for some reason the configure script didn't process 
the makefile.in for portaudio.

This is expected.  As far as I know, the only time portaudio has ever been 
built with Cygwin is here in AUdacity.  ;)  I don't remember if I sent the 
makefile.in I wound up with over there, since it was pretty customized to 
Audacity at the time.

Ok, Audacity built under Cygwin right before the 1.2 release of Audacity, so 
if you dig up a copy of Audacity 1.2.0, the instructions should work fine.  
(I haven't had a chance to screw with it, and now I'm stuck with Windows in a 
vmware session, which isn't all bad, but on an 800mhz Duron I'm not in a 
hurry to start up a huge build of Audacity in Cygwin)  I would suggest 
backing up to that specific version and starting somewhat fresh.  Get it 
working with the older, known working version, with all the libraries (I had 
it working with all of them, iirc).

If you do it from cvs by checking out the tagged 1.2.0 version, you should 
then be able to update your local sandbox to each successive versions, fixing 
as you go.  What you'll wind up with is a nice mega-patch that'll bring the 
latest versino of Audacity up to date with Cygwin.  :)

So, yeah, it coudl be you, but it could be Audacity too.  I don't even have 
the computer I did all that on anymore, otherwise I'd send you a dump of what 
packages were installed so you could mimic it.

(in case you were curious, I did the Cygwin build mostly because I wanted to 
learn how building programs in Cygwin were different from the same process 
natively in Linux.  Learned a lot, too :)  )
