This means that you tried to call a method of something that's not an object
(= blessed reference).
In the following example, the error is triggered because $href is just a
simple hash reference:
$ perl -le '
use strict; use warnings;
my $href={a => "b"};
$href->print;'
Can't call method "print" on unblessed reference at -e line 4.
In the next example, a blessed reference is used, but the method does not
exist:
perl -le '
use strict; use warnings;
my $href=bless {a => "b"}, "SomeClass";
$href->print;'
Can't locate object method "print" via package "SomeClass" at -e line 4.
If this does not help,
- provide code
- read some perl documentation, f.e.
perldoc perlobj
perldoc perlmod
- wait for answers of one of the list gurus
