Hello Cygwinstas,
I've got a question about the cygwin perl package installed with cygwin setup.
I'm having a failure in some perl code not written by me but rather in a CPAN
module I am seeking to install. This failure does not occur on Gnu/Linux. The
first 10 lines of that module are:
package Array::Contains;
use 5.010_001;
use strict;
use warnings;
use diagnostics;
use mro 'c3';
use English;
our $VERSION = 2.8;
use Carp;
Line 6 contains the directive to use the diagnostics pragma as you see. But
when the perl compiler hits that line, it dies with the following long and
slightly confusing messages:
$ perl '-Mdiagnostics' -le 'print $diagnostics::VERSION'
couldn't find diagnostic data in /usr/share/perl5/5.40/pods/perldiag.pod
/usr/share/perl5 /usr/local/lib/perl5/site_perl/5.40/x86_64-cygwin-threads
/usr/local/share/perl5/site_perl/5.40
/usr/lib/perl5/vendor_perl/5.40/x86_64-cygwin-threads
/usr/share/perl5/vendor_perl/5.40 /usr/lib/perl5/5.40/x86_64-cygwin-threads
/usr/share/perl5/5.40 -e at /usr/share/perl5/5.40/diagnostics.pm line 259,
<POD_DIAG> line 718.
Compilation failed in require.
BEGIN failed--compilation aborted.
I'm following up on my own message here. I've been discussing it with
monks over at perlmonks (https://perlmonks.org) and someone there
(monk named choroba) knew what was wrong; the file
/usr/share/perl5/5.40/pods/perldiag.pod is, on Cygwin, not installed
automatically with the base perl executable, library and core modules.
It's in, rather, the optional package <<perl_pods>>. So I installed
that package and the problem went away.
One entry not yet in the FAQ is that Cygwin packages mainly split non-trivial
docs, including those with lots of man pages, into separate -doc sub-packages.
