make fails: No rule for target READMEmd

Installing Compress-Raw-Zlib-2.207.tar.gz from CPAN fails, possibly due to a5e8a4e:

Thanks @johannessen

the READMEmd target was added in the change I added yesterday for 2.207.

I don't see the error you are getting on my Linux dev setup, so I assume there must be something different about how a Mac build works.

If you have the time could you try editing private/MakeUtil.pm and add the else block .

    if (-e '.github' && exists $params{name})
    {
        my $name = $params{name};
        $postamble .= <<"EOM";

READMEmd: .github/$name.pod

.github/$name.pod: lib/Compress/Raw/$name.pm
	\@echo Creating .github/$name.pod from $name.pm
	\$(NOECHO) perl -ne 'print unless 1 .. /^__END__/' lib/Compress/Raw/$name.pm >.github/$name.pod

EOM
    }
    # ADD THIS ELSE BLOCK
    else
    {
        $postamble .= <<"EOM";

READMEmd: 

EOM
    }

Actually I first got this issue in a Linux GH action, so macOS is unlikely to be the culprit here.

I suspect your dev setup either has PERL_CORE set or has a .github directory present. From reading the commit I mentioned earlier, it looks like either of these things would prevent you from seeing this particular issue.

With the else block added, make and make test succeed.

I test this module in a series of GH workflows without a problem (although they will have the .github directory.)

I suspect your dev setup either has PERL_CORE set or has a .github directory present. From reading the commit I mentioned earlier, it looks like either of these things would prevent you from seeing this particular issue.

No, I've deliberately build the module away from my dev source tree, so no .github directory is present. Also, don't have PERL_CORE set.

With the else block added, make and make test succeed.

Thanks for testing that out for me.

Interesting. In that case, I don't know why it was failing for me, but not for you.

Thanks for testing that out for me.

No problem. Thanks for looking into it!

2.208 resolves the issue. Thanks for the quick fix!
