I do apologise, it appears I c&p'd the wrong log. This is the one I should have posted

As you can see, I have installed Exception::Class, but I am still getting failures from 03threads.t

    This looks to be a bug in Perl and may be related to this bug fix reported in perl585delta.pod:
    Creating a new thread when weak references exist was buggy, and would often cause warnings at interpreter destruction time.
    I'll investigate this further. Thanks.

    Update:
    After further investigation, I'm fairly sure this is a Perl bug. I could not reproduce the error you received under Cygwin or Solaris, but I did reproduce the warnings mentioned in the quote above. Further, 03-threads.t and 04-shared.t are nearly the same, and 04-shared.t successed for you. I can only recommend upgrading to Perl 5.8.7 if you can.

    I'll make note of these sorts of issues in the bug section of the POD.


    Remember: There's always one more bug.

      I got around to installing 5.8.7 and attempted a rebuild of Object::InsideOut, and got the same failures as before, but this time noted that Makefile.pl produced a warning

      Locally installed version of Scalar::Util does not support weakened references. It is strongly recommended that you download the lastest +version of the Scalar-List-Utils module from CPAN, and attempt to remedy this deficiency. View this module's documentation for further information. Writing Makefile for Object::InsideOut

      I tracked that down to the XS version not having been built/distributed as a part of 5.8.7. So I pulled the CPAN version and attempted to build it, and it refused to attempt to build. That I tracked down to the can_cc() apparently returning false.

      Cutting a long story short(ish), harcoding the $do_xs var in the Scalar-List::Util Makefile to true, allowed me to cleanly build the xs version, making the isweak() and other XS-only functions available. With that, O::IO builds, tests and runs clean.

      Why can_cc() fails I cannot work out, but...if you get other failures on Win32, that would be a good starting point.

      I should probably raise a bug report against something, but what? AS 813, SL::U or MakeMaker?

      "Science is about questioning the status quo. Questioning authority".

        The problem comes from can_cc() using the 'cc' value in Config. Thus, the bug is in Module::Install - in inc/Module/Install/Can.pm. It needs to accommodate ExtUtils::FakeConfig, replacing "use Config;" with:
        eval { require Config_m; }; # ExtUtils::FakeConfig (+ ActivePerl) if ($@) { eval { require Config; }; # Everyone else }
        Then on your end, you'd need to install and configure ExtUtils::FakeConfig to have the correct 'cc' entry.

        Or you could just edit your Config.pm, and change the 'cc' entry to something that works.
