As has been customary for decades please post a small, self-contained
program that exhibits the problem and that other people can run and
test.

This statement is a little cryptic. Let's assume that the package name
is Arthur. In this case, the error message

Error : Can't locate object method "new" via package Arthur
(perhaps you forgot to load Arthur)

means there's a call to a method named new (usually a constructor)
using Arthur as invocant, eg

my $dent = Arthur->new();

but the symbol table of the package Arthur didn't contain an entry for a
subroutine named new. Usually, the cause is just what the error message
suggests: It wasn't loaded, a statement a la

use Arthur;

is missing. You should provide some more information about your problem
if that wasn't the cause.

Hello,

I am having a similar issue. Unsure if I should start a topic or can continue here. Until now, I was using perl 5.12 and my code was working fine. Now we upgraded to fedora19 and perl 5.16, my code errors saying
Can't locate object method "new" via package "MyModule" .
I have been using the inheritance concept in MyMdule to use a common constructor from a parent class "ParentModule".

package ParentModule;
use SomeModule::API;
our @ISA = qw(Exporter SomeModule::API);

sub new{
my $class = shift;
my %settings;
my $self = $class->SUPER::new(\%settings);
bless $self, $class;
return $self;
}

package MyModule;
our @ISA = qw(Exporter NetMRI::BVT::BVTCommon);

#use parent constructor



test.pl #my script to test the setup
use MyModule;

my $obj = MyModule->new(@input);
$obj->$method;


Can anyone please help with what has changed from perl 5.12 to 5.16 thats causing this error. Or what change can I make in order to get this working.
I have even tried writing a constructor in MyModule using SUPER::new, but get the error saying
Can't locate object method "new" via package "MyModule::SUPER"

Since MyModule isn't derived from ParentMode, there's no way it could
possibly inherit ParentModule methods.

Hello,

Please take a look at the new piece of code. The deriving of the ParentModule was missed in my previous post.
