Please start reading the documentation for Text::CSV_XS or Text::CSV. To me this error indicates that you forgot to initiate the $csv object (or that you are using a very old Text::CSV):
use Text::CSV_XS; # or use Text::CSV; my $csv = Text::CSV_XS->new ({ binary => 1, auto_diag => 1 });
update: can I see both the script and the data? Not much has changed for getline_all () in Text::CSV_XS since Dec 2010, when it was introduced
