Thanks for reporting.

Is this the first time you try to bootstrap the Cygwin build?  If so,
please look for relevant entries in PROBLEMS, and make sure you don't
trip on any of the Cygwin-related gotchas mentioned there.  In
particular, the one with GCC versions.

This often happens in bootstrapping under Cygwin.

Solution: build in a separate directory and/or build from an
"xterm" console (NOT the dos-like console)...

...or use prebuild (22.0.97-pretest) Cygwin binaries from
http://www.webalice.it/angelo.graziosi/Emacs.html.

To build use GCC-4.0.3 or 4.0.4 which seem to give very stable binaries.



Cheers,

   Angelo.

Yes, or at least, the first time in years.

I did indeed have gcc 3.4.4, which that file mentions doesn't work.
Thanks, that explains the failure.  But it leaves me with two
questions:

* Couldn't "configure" detect the gcc version, and fail if it finds
  that we're using any of those bad gcc versions on Cygwin?  That
  would have saved me and you time.

* Do I need to build gcc 4 myself from source?  It doesn't appear to
  be available from Cygwin's setup program.

I'm not sure this is such a good idea, since the problems that cause
this could be fixed in the near future, and new GCC versions appear
much faster than Emacs releases.  We could be left with gratuitous
failures very soon.

I hope someone who uses Cygwin, like Angelo Graziosi, can help you
here.

For what it's worth, I just built gcc 4 from source, which went
perfectly smoothly, and then built emacs from that, which also went
perfectly smoothly.

Thanks for reporting this, and for trying the Cygwin build in the
first place.

Hi Eric,

I have tried to send (by attaching, 3 MB) the Cygwin binaries of GCC-4.0.4
with which the Emacs-cvs build works fine but it seems that something went
wrong and the replay is absent from this list.

In any case I have seen that you have solved building yourself GCC-4 and
this is good.


Cheers,

   Angelo.
