in reply to help debugging why module install is failing

G'day Special_K,

I have Cygwin running on Win10, so thought I'd give this a go to see if I got any different results. My Perl is 5.32.0; I used the cpan utility: cpan[1]> install IO::Async::Listener.

I got the same Failed test 'exceptional socket invokes on_read_ready' for t/10loop-poll-io.t and t/10loop-select-io.t.

I got the same six warnings for t/42function.t: Warning: unable to close filehandle ... during global destruction.

This, however, was different from your report: 

t/50resolver.t ............... ok
t/51loop-connect.t ........... 1/? Nothing was ready after 10 second w
+ait; called at t/51loop-connect.t line 322
# Tests were run but no plan was declared and done_testing() was not s
+een.
# Looks like your test exited with 119 just after 31.
t/51loop-connect.t ........... Dubious, test returned 119 (wstat 30464
+, 0x7700)

Here's the full summary if you want to make a comparison:

    It may just be that Cygwin doesn't do exceptional-condition monitoring on those filehandles, at which point there really isn't anything this module can do about it. Could just skip those parts of the tests or something.

    How were you able to get Perl 5.32.0 on Cygwin? When I run the Cygwin setup utility, the most recent version listed for the perl Package is 5.30.3-1.

      I don't know how leonerd kcott obtained it, but it built pretty easily for me from source. (Yes, that surprised me, too !)
      IIRC, I ran: 
      ./Configure -des -Dprefix=/your/preferred/location
make 
make test (might fail a test or two ... can't remember that part)
make install

      "How were you able to get Perl 5.32.0 on Cygwin?"

      Short answer: I used Perlbrew.

      Detailed answer: "Re: Perl on Windows 10". That actually got me 5.30.0 (at that time, Cygwin had 5.26.3). I don't remember the exact details of how I upgraded that to 5.32.0, but it was probably just: 

      perlbrew install perl-5.32.0

      [download]

      So now I have: 

      $ perl -v | head -2 | tail -1
This is perl 5, version 32, subversion 0 (v5.32.0) built for cygwin-th
+read-multi

      You may also be interested in "App::perlbrew - Compiling Perl with thread support". It's possibly somewhat dated: I wrote it in 2012 and added an update in 2014. I didn't need to do anything special to get thread support this time around on Cygwin: I don't know if defaults have changed or this was platform-related (I was using Mac OS X back then).
