On CygwinPerl, Digest::SHA fails all tests (yet passed on CPAN-testers)

[somian]

I've got trouble trying to install the module Digest::SHA 5.34 to a
cygwin installation that seems otherwise healthy and "normal" (can
install other pure-perl and xs-perl CPAN modules).

The very first test t/1-exist in the test suite dies, for example.

Partial screenscrape of Perl debugger session showing where program
dies:

I've searched the Cygwin lists and cygwin-perl on Yahoo!Groups, no info
that seemed relevent, so if anyone has an insight please reply. TIA.

That test simply tries to load the module you've just (successfully) built.
What happens if you run:

perl -Mblib t/t1-exist.t

Hi, Sisyphus, thanks for replying.

Precisely what happens when I tried the above just now was this:

$ perl -Mblib t/1-exist.t
1..1

# Current time local: Wed May 10 00:30:31 2006

Yuk.

So if you change t/1-exist.t so that it contains simply:

use Digest::SHA ();

and then re-run 'perl -Mblib t/1-exist.t', do you find it still segfaults ?
I wouldn't know what to make of a segfault caused by merely loading a
module. Were there any compiler warnings during 'make' that might give a
hint to the cause ?

I'm glad I don't use Cygwin :-)

Cheers,
Rob

I finally tracked down the real cause of the failure, and the
"executive summary" version is that it wasn't Digest::SHA's fault at
all.

There was a MIME::Base64 module in my @INC pathlist that was generating
a segfault each time loading it was attempted. Thus any module that
used it (like Digest::SHA) would fail at the loading stage.

The @INC included modules built for cygwin perl 5.8.2. Removing the
offending installation of MIME::Base64 (that was 'shadowing' the one
shipped with Cygwinperl) fixed the problem.

Glad that's figured out, now I can presumably have hashsum-checking on
CPAN modules I'm installing.

Heh :-)
That's a pretty mean trick - and unexpected (by me, at least) that such an
incompatibility should exist.

Good that you got it sorted.
