Kwalitee Issues


Change the permissions of Build.PL/Makefile.PL to not-executable.


Add a Changelog (best named 'Changes') to the distribution. It should list at least major changes implemented in newer versions.


Add a META.yml to the distribution. Your buildtool should be able to autogenerate it.


Run a proper command ("make manifest" or "./Build manifest", maybe with a force option), or use a distribution builder to generate the MANIFEST. Or update MANIFEST manually.


  • MANIFEST (11) does not match dist (42):
  • Missing in MANIFEST: examples/, examples/, examples/gowilogo.png, examples/, examples/, examples/pumpkin.png, examples/, examples/, examples/, examples/, examples/, examples/turkey.png, imgs/compblpa.png, imgs/dbdchart.gif, imgs/grey.jpg, imgs/iconbar.png, imgs/iconhisto.png, imgs/logtempline.png, imgs/multarea.png, imgs/multibar.png, imgs/multipt.png, imgs/quadtree.png, imgs/samplebox.png, imgs/simpcndl.png, imgs/simpgantt.png, imgs/simppie.png, imgs/simppts.png, imgs/simpsymb.png, imgs/simpylog.png, imgs/stack3dbar.png, imgs/stackarea.png


Remove the POD errors. You can check for POD errors automatically by including Test::Pod to your test suite.

Error: DBD-Chart-0.82/Chart/ -- Around line 4560: You forgot a '=back' before '=head1'Around line 4596: '=item' outside of any '=over'Around line 4776: You forgot a '=back' before '=head2'Around line 4891: '=item' outside of any '=over'Around line 4933: You forgot a '=back' before '=head1'Around line 4935: '=item' outside of any '=over'Around line 4945: You forgot a '=back' before '=head1'


List all used modules in META.yml requires


  • DBI
  • GD
  • GD::Text
  • GD::Text::Align


Split the distribution, or fix the version numbers to make them consistent (use the highest version number to avoid version downgrade).

Error: 0.81,0.82


Add a META.json to the distribution. Your buildtool should be able to autogenerate it.


Define the license if you are using in Build.PL. If you are using MakeMaker (Makefile.PL) you should upgrade to ExtUtils::MakeMaker version 6.31.


Add 'use warnings' (or its equivalents) to all modules (this will require perl > 5.6), or convince us that your favorite module is well-known enough and people can easily see the modules warn when something bad happens.

Error: DBD::Chart, DBD::Chart::Plot


List all modules used in the test suite in META.yml build_requires


  • DBI


This is not a critical issue. Currently mainly informative for the CPANTS authors. It might be removed later.
