Bug #25364 for IO-Compress-Base: Scalar::Util

Sat Mar 10 07:48:20 2007 jettero [...] cpan.org - Ticket created

Subject:

Scalar::Util

Scalar::Util aught to be in the PREREQ_PM. It was unobvious why my build of Compress::Zlib failed as 4,000,000 lines of errors scrolled past, but in the end, it was this missing prereq. -- If riding in an airplane is flying, then riding in a boat is swimming. 85 jumps, 36.0 minutes of freefall, 69.1 freefall miles.

Curiously, it is indeed in the prereqs, but failed to actually require in my build environment... Show quoted text

Apparently, it requires the XS version even though you can't require that? Perhaps the PREREQ_PM should require more than 0? -- If riding in an airplane is flying, then riding in a boat is swimming. 85 jumps, 36.0 minutes of freefall, 69.1 freefall miles.

Yep, as you discovered Scalar::Util is indeed in the prereq list. Unfortunately Scalar::Util can be built to either use XS or nor use XS, so making a prereq of a specific version will not help. Paul

K. I have a workaround, so this is pretty unimportant. My complaint is that this way CPAN doesn't automatically pull in Scalar::Util and the test fails without it; making my complicated build process fail. My workaround was to install Scalar::Util (because why wouldn't you want that) before IO::Compress::Base installs, but I suppose I could have just ignored the test results instead. I dislike ignoring the test results... but that was the other obvious choice. -- If riding in an airplane is flying, then riding in a boat is swimming. 85 jumps, 36.0 minutes of freefall, 69.1 freefall miles.

I would suggest raising this to critical as I have just tried to install Bundle::CPAN on a clean Debian system, and ALL the Zlib modules that require it now FAIL. As Scalar::Util is now a CORE module (as of 5.7.3), how its built is completely in the hands of the person building the package. If you require the XS version I would recommend adding something at the top of your FAQ that explains that and how to do it. This is likely to create a bad impression to users unfamiliar with the installation mechanism.

Can I just double check that you are seeing the non-XS version of Scalar::Util issue? (there is another CPAN + Compress related issue that I'm sorting out). Show quoted text

What version of perl do Debian ship? If it was 5.10 this problem should not occur. Show quoted text

At the moment the IO;;Compress::Base test harness should fail one of its tests if the non-XS Scalar::Util is present. Was that not enough to stop the install of Bundle::CPAN in its tracks? Paul

I'd like also to vote for raising this to be a critical bug. I've just installed 5.8.8 (from sunfreeware) on a sparc solaris box, and hit this when trying to install CPAN, and LWP. cpan[13]> install Scalar::Util Scalar::Util is up to date (1.19).

While some documentation would have helped me get further, I seem to have found some other 'fun' issues with CPAN.

This is a duplicate of RT #27598 (https://rt.cpan.org/Ticket/Display.html?id=27598) No way with this bug tracking to flag this as a duplicate, so marking as resolved.
