  • Actually... (Score:1)

    Every single Fail report on v0.1.4 is due to "No 'Makefile.PL' found - attempting to generate one".
    Actually, every fail report is due to:

    [ERROR] [Mon Jul 16 19:12:23 2007] This module requires 'Module::Build' and 'CPANPLUS::Dist::Build' to be installed, but you don't have it! Will fall back to 'CPANPLUS::Dist::MM', but might not be able to install!

    The clue is in the [ERROR] tag...

    I would prefer to *not* include Makefile.PL at all because there is another configuration scheme which says "prefer Makefile.PL over Build.PL?" (And of course it defaults to the wrong answer.)

    You will keep running into issues like these until either all machines have Module::Build support, or the config_requires: extension to META.yml is accepted, implemented and supported in all deployed versions of CPAN.pm/CPANPLUS.

    The traditional approach has been to at least use Module::Build's compat() feature to generate a Makefile.PL.

    In this case, the tools do as best they can, and fail for obvious reasons.

    • When CPANPLUS says:

      [ERROR] [Mon Jul 16 19:12:23 2007] This module requires 'Module::Build' and 'CPANPLUS::Dist::Build' to be installed, but you don't have it! Will fall back to 'CPANPLUS::Dist::MM', but might not be able to install!

      and then

      No 'Makefile.PL' found - attempting to generate one

      it is trying to be helpful. But the smoker module (be it CPAN::YACSmoke, CPAN::Reporter or whatever) should recognize this case as NA and not FAIL. Would it be hard to tell this case apart?

      On another note, Bundle:

      • generating a traditional Makefile.PL in the name of compatibility.

        Isn't that more courtesy towards the user than some old ritual one has to follow? I'm constantly amazed by such ideas as Module::Build::Convert [cpan.org], which tries to automate a process for which there is absolutely no need - if it works with a Makefile.PL why move to Build.PL at all.

        • Isn't that more courtesy towards the user than some old ritual one has to follow?
          Yes. But we want to encourage users to move to brand new updated tools, don't we? Using only Build.PL makes sense if (1) that is supposed to work only for newer Perls and installations, or (2) you don't care if your module does not work unless people have up-to-date toolchains.

        • a process for which there is absolutely no need

          That depends on whether you consider EU::MM fundamentally broken or not.

      • Would it be hard to tell this case apart?

        Actually yes it is. This part of the configuration is not captured well in EU::MM and M::B and as a consequence CPAN.pm and CPANPLUS have to jump through hoops to get at it. Last time I checked EU::MM handles this better.

        recognize this case as NA and not FAIL.

        NA has a specific meaning, in that the module does not work on that perl/platform. This isn't the case in this situation, so should be a FAIL as the author is not providing support for the current standard toolchain. If they choose to insist on M::B then at the moment that will break be
