Problem mit perl -cw /bin/cgi-bin/index.pl

[TobiasFrei]

Hallo zusammen,
momentan läuft unser OTRS unter einer relativ alten Version unter Windows. Ich möchte testweise auf Debian migrieren, bekomme allerdings mit dem Syntaxcheck Probleme. Version ist 3.1.11.

Ist das hier relevant? Und falls ja, wie kann ich das beseitigen?

Grüße und danke

Tobias

Unter "neueren" Perls (schon seit ein paar Jahren) gibt es diese Warnung...

Bei https://github.com/OTRS/otrs/blob/rel-3 ... ls.pm#L811 einfach aus

Code: Select all

       (                                          # $4
            ?=(?:

Code: Select all

       (?=(?:

machen...
