Perlapp and DateTime::TimeZone

Unfortunately I'm confined to an old ActivePerl (5.12) and a fittingly old PerlApp (9.2.1).

There seems to be an issue with newer releases of DateTime::TimeZone, such that perlapp adds all the timezone pm files (it's visible with --verbose for example), but regardless the application cannot find it.


use utf8;
use strict;
use warnings;

use DateTime::TimeZone;

# system("pause");

my $localtz = DateTime::TimeZone->new(name => 'local');

print $localtz->name() . "\n";

This triggers the error, it runs nicely unpacked, but when packed it cannot find for example the Europe/Prague time zone (DateTime/TimeZone/Europe/

--add doesn't seem to help at all, if I pause the program, I don't even see the files in any of the temp directories. Contrary to what's been said in other topics, --add Params::Validate::PP didn't work either, while using --bind did.

So the build batch file looks like this currently:

perlapp --force ^
        --add "DateTime::TimeZone::" ^
        --bind DateTime/TimeZone/Local/[file=C:\perl\site\lib\DateTime\TimeZone\Local\,extract] ^
        --bind DateTime/TimeZone/Local/[file=C:\perl\site\lib\DateTime\TimeZone\Local\,extract] ^
        --bind Params/Validate/[file=C:\perl\site\lib\Params\Validate\,extract] ^
        --bind Params/Validate/[file=C:\perl\site\lib\Params\Validate\,extract] ^
        --bind Class/Load/[file=C:\perl\site\lib\Class\Load\,extract] ^

The --add line is entirely useless; right now I guess I should just generate --binds for all the timezone files manually and --trim DateTime::Timezone::* so it doesn't use space unnecessarily.

There's an endless tug-of-war between maintainers adding new features and the internal special treatment rules that PerlApp needs to manage modules that are otherwise incompatible. There will come a point (and you might be there already) when you should consider suspending further updates from PPM for the duration of the time you remain on 5.12 and PDK 9.2.

Thanks for the reply!

Yeah, I was suspecting Module::Runtime too, the installation of some module (via cpanm) must have upgraded it.

I would have switched to 5.18 or newer, but all my attempts at getting GTK and AnyEvent (or even IO::Async) work together, that worked just fine in 5.12, failed with the GUI stopping updating entirely. Same code would run just fine on Linux. And in 5.22 I don't appear to have a working PPM at all, after a fresh install. So I have to make do with what I have.
