Arch Linux

Description:

Auto Multiple Choice (AMC LaTeX) in version 1.4.0-3 fails to start with the current Perl version (5.30).

Steps to reproduce:

$ LANG=C auto-multiple-choice

Can't locate Locale/Language.pm in @INC (you may need to install the Locale::Language module) (@INC contains: /usr/lib/perl5/5.30/site_perl /usr/share/perl5/site_perl /usr/lib/perl5/5.30/vendor_perl /usr/share/perl5/vendor_perl /usr/lib/perl5/5.30/core_perl /usr/share/perl5/core_perl) at /usr/lib/AMC/perl/AMC-gui.pl line 43.
BEGIN failed--compilation aborted at /usr/lib/AMC/perl/AMC-gui.pl line 43.

I tried to locate the Language.pm file with pacman -Fs Language.pm, in case the file has been moved to another package, but this doesn't seem to be the case.

Workaround:

Remove the "use Locale::Language;"-Line at 43 in file /usr/lib/AMC/perl/AMC-gui.pl, then AMC runs. Surprisingly with a German GUI (if I omit LANG=C and use my default German locale), so the Locale::Language seems to not be responsible for GUI i18n, but surely for something else that will crash the application at some point.

I don't know anything about Perl, but the documentation shows that the Locale::Language module is present at 5.28 but not at 5.30. See: https://perldoc.perl.org/5.28.0/Locale/Language.html.

Upstream should port the application to the new Perl version. Other Linux distributions will be affected too when they upgrade Perl. The next Debian Stable (Buster) will come with Perl 5.28, so running AMC in a Debian container might be a workaround for users too.
