    This is actually from last August, but I haven't come across it until today.

    Marketing Strategy for the Next Two Years (

    The question for us, I think is: What impact will this have on PerlMonks? Will we be required to modify/restrict our "look and feel" to conform to the branding guidelines set by TPF?

    I reckon we are the only monastery ever to have a dungeon staffed with 16,000 zombies.

    Aron Wall quotes his dad Larry Wall in an interesting blog post:

    As my Dad said in an interview once about the philosophy that motivated him to make the Perl programming language:

    The philosophy of TMTOWTDI ("There's more than one way to do it.") is a direct result of observing that the Author of the universe is humble, and chooses to exercise control in subtle rather than in heavy-handed ways. The universe doesn't come with enforced style guidelines. Creative people will develop style on their own. Those are the sort of people that will make heaven a nice place.

Interested readers can do their own research to discover the context of and reaction to the report. The author of this post felt that a "permaban" on a Perl contributor was newsworthy in itself.

    Sander has posted this message on the mod_perl mailing lists today. In essence, mod_perl needs more PMC members to prevent Apache kicking it upstairs to the Attic (whence nothing returns).

    If you have the ability, the time and the inclination, please consider stepping forward to help secure the future of this important Perl project.

Quadmath builds of perl for MS Windows

    Not sure that anyone here is particularly interested in this, but I'll mention it anyway that, as of the release (on 20.01.2021) of perl-5.33.6, it's possible to build perl on MS Windows with an NV type of __float128.
    And it has become a little easier in 5.33.7 with a change to GNUmakefile that removed the need for a somewhat cumbersome configuration argument.
    With the release of perl-5.22.0, the NV type of long double was enabled on Windows, and now we finally get the additional option of having the __float128 NV type.
    All of this does, of course, rely on using mingw-w64 ports of gcc to build your Windows perl.

    I think that many of us, accustomed to simply using Strawberry Perl, don't realize just how easy it is to build perl from source on Windows.
    Strawberry Perl, itself, does provide us with the toolchain that's capable of building any recent version of perl (including blead releases) from source.
    The latest blead source can be obtained with:
    $ git clone blead_clone
    or the perl-5.33.7 development tarball is available from:
    Then, I place my C:\_64\strawberry-5.32.0\c\bin folder at the beginning of my PATH, and I have all that I need to build perl.
    Simply cd to the perl source's win32 folder and run:
    gmake INST_TOP=C:\bleadstraw CCHOME=C:\_64\strawberry-5.32.0\c CCTYPE= +GCC I_QUADMATH=define USE_QUADMATH=define test
    Then, to install perl into the location specified by INST_TOP, just run:
    gmake INST_TOP=C:\bleadstraw CCHOME=C:\_64\strawberry-5.32.0\c CCTYPE= +GCC I_QUADMATH=define USE_QUADMATH=define install
    And that's it - in C:\bleadstraw I now have a Windows perl that has __float128 as its NV.

    You may want to alter INST_TOP, and you probably need to alter CCHOME which should specify the full path to gcc's bin directory.
    NOTE that CCHOME does not include "\bin". (Failure to get CCHOME right will cause some test failures, but will not affect the perl that has been built.)

    If you want to do a 'long double' build instead, you would just remove the 2 gmake arguments that include the string "QUADMATH", and insert the USE_LONG_DOUBLE=define argument.
    If you don't request either a 'long double' or a 'quadmath' build, then the nvtype will be 'double'.

    If you're using a 32-bit compiler, you'll also need to insert the argument WIN64=undef, and you might also want to add the argument USE_64_BIT_INT=define if you want 64-bit integers and pointers.
    With 64-bit compilers, perl's integer and pointer will inevitably be 64-bit.

    I think that covers the most commonly exercised options ... but you'll find additional options laid out in the GNUmakefile.

    I don't know if it's a general issue, but (on 64-bit builds only) there's usually a couple of test scripts in cpan/IO-Compress/t that hang for me .
    Update: This issue is a long-standing one for me, and is not limited to just the "quadmath" builds.
    It's generally (but not always) the same test scripts that hang, and it has been happening for a few years. In perl-5.33.7, I'm finding that the problem has moved to a different couple of files.
    The Strawberry project have never, to my knowledge, complained about such an issue - so I'm hoping that it's just something in my particular environment.
    It would be nice to find out if it is "just me".
    It's quite annoying - I have to kill these hangs using process explorer in order to get the test suite to run to completion. (Killing them with Ctrl-C kills the entire 'gmake test' process.)
    These test scripts have always passed when run outside of the testing harness, and they've also passed even when I've run make test in the cpan/IO-Compress folder.
    There's also the same thing happening in the cpan/IPC-Cmd tests with t/01_IPC-Cmd.t.
    If I can find any evidence that it's also an issue for others then I'll try to get it fixed.

    Oh, one last thing - if you build a 32-bit perl with I_QUADMATH=define USE_QUADMATH=define but without USE_64_BIT_INT=define, then expect some failing tests in Math::BigFloat due to a Math::BigInt::Calc bug.
    This issue has been reported, with a proposed simple fix to

    I've released berrybrew version 1.33. This version has significant enhancements, along with some bug fixes and handling of some uncaught exceptions. The changes reflect versions 1.30 to 1.33.

    Major changes include:


    • Allows you to install, switch to, remove and use Strawberry Perls directly
    • Can now spawn a CLI window for any Perl you have installed
    • Allows you to spawn a CLI window for the currently active Perl
    • Provides access to modify several of the core configuration options (debug, file association etc)
    • Allows you to disable all berrybrew Perls and restore to system default


    • Performs an upgrade on any previous berrybrew install
    • Adds any new configuration options, while preserving the values of any previously set existing ones
    • Provides facility to install the most recent version of Strawberry Perl
    • Allows you to have berrybrew manage the .pl file association
    • Allows you to have the UI run at system startup
    • Aborts if trying to install the same version that's already installed


    • You can now leave off the _32/_64 bit prefix on a Perl name, and we'll default to _64
    • All execution paths return a proper exit code
    • Added new berrybrew hidden command, lists all, well, hidden commands

    For all other changes, please refer to the Changes file.
