locked_user sundialsvc4 has asked for the wisdom of the Perl Monks concerning the following question:

What can cause:
Can't locate object method "new" via package "x::y::z" (perhaps you forgot to load "x::y::z"?

in response to:
my $foo = x::y::z->new(...);

when you can plainly see that the module in question does contain:
use x::y::z;

and that the file x/y/z.pm includes a proper package statement:   (all examples match WRT case-sensitivity, etc.)
package x::y::z;

?

This is a case-insensitive filesystem and the module in question can be compiled correctly and can be used.   There are no CaSe MiSmAtCh problems.   There is no hanky-panky going on with @INC or anything like that.   I can, in a command line one-liner, 'use x::y::z; my $foo=x::y::z->new();' and it works.

I know that similar issues have been discussed in the recent past, but this does not seem to be quite the same thing.   Is there a previous posting that anyone can point me to on this one?   I am genuinely puzzled as to what Perl is trying to tell me.

    Do your modules use each other (circularity)? I've seen similar things happen when you attempt to use methods prior to them being defined in the compile phase. I get a similar error with:

    Foo.pm 

    package Foo;
use Bar;

sub new {
    return bless {}, shift;
}

1;

    [download]

    Bar.pm: 

    package Bar;
use Foo;

sub new {
    return bless {}, shift;
}

my $foo = Foo->new();

1;

    [download]

    script.pl: 

    #!/usr/bin/perl
use strict;
use warnings;

use Foo;

    You might try inspecting your symbol tables (Devel::Symdump or the like).

    Maybe you have some non-printing character(s) somewhere? I have had, after cut-and-paste operations.

      If I could do that, I wouldn’ be askin’, eh?

        Why not? You start deleting code until you have a minimal example that demonstrates the problem
