Intrepid has asked for the wisdom of the Perl Monks concerning the following question:

(SBP means "Strawberry Perl")

I am not thoroughly knowledgeable about the NTFS (my Windows 11 filesystem is NTFS), but it appears there's a portability gotcha in File::Copy::Recursive::Reduced, as illustrated in the console output below: 

"C:\berrybrew\instance\5.40.2_64\perl\bin\perl.exe" "-MExtUtils::Command::MM" "-MTest::Harness" "-e" "undef *Test::Harness::Switches; test_harness(0, 'blib\lib', 'blib\arch')" t/*.t

I was not actually aiming to test or install File::Copy::Recursive::Reduced, but it was a dependency for Mouse.

As always, I will greatly appreciate any knowledge and insights. Thanks, good monks.

    The CPAN testers results for Windows are a mix of successes and failures like yours.

    It fails for me as well.

    There's no reported bugs.

    I thought it might be a difference in C runtime, but I see passes for both cl and gcc, and I see failures for both cl and gcc. I would expect all cl builds to behave the same if that was the case.

    I don't have time to look further into the differences between the builds at this time.

    PS — If you read the docs for File::Copy::Recursive::Reduced, it was written to address one or more ongoing unfixed issues in critical ("high upstream") module File::Copy::Recursive. Now it's File::Copy::Recursive::Reduced in that position.

      Hi ikegami. Thanks for your reply. I totally understand if you don't have time at present to investigate further.

      I did not look at RT before posting my node, bad me, I should know by now that I must always do that before I post if I'm going to offer these "so-and-so doesn't work" postings.

      I was just a little late off the starting line on this one - just before seeing this reply from you I was reading the POD for said module. You are quite correct. But File::Copy::Recursive is still failing tests (on MSWin32 and Dragonfly BSD), though, so both the original module and the "fixed" module, are, as you say, in that position. This is not good.

      On my Gnu/Linux system I have File::Copy::Recursive v0.45, and on StrawberryPerl the same.
