Perl version changes? [duplicate]

Question

I wrote some perl cgis 20 years ago. They worked perfectly ... until my hosting company has updated my machine last week. A Perl cgi blocks. It seems it is because the following sequence :

require "quiest.htm";
require "quiest.pay";
require "quiest.ent";

is not understood as meaning "use these three scripts in the same directory" anymore.

Which would be the correct entry?

I tried quite everything else in terms of reloads, site reorganizing, etc. (the script is called by an HTML page requesting a user entry) everything resulted in a "site.tld\nameof.cgi?string=xxxxx 404)

Answer 1

They removed the current directory (.) from @INC in Perl 5.26.

The link above includes some solutions:

• You can set the PERL_USE_UNSAFE_INC environment variable to 1.
• Manually add your secure path to @INC:

BEGIN {
    my $dir = "/some/trusted/directory";
    chdir $dir or die "Can't chdir to $dir: $!\n";
    # safe now
    push @INC, '.';
}

Also, as @ikegami reminded me in the comments, FindBin exists:

use FindBin;
use lib $FindBin::Bin;
