I'm trying to learn to develop Perl modules in an effort to have clean
directory structure and more reusable code.
I'm hitting a little snag in my test code that I don't quite understand. I'm
hoping someone can help explain where I may be going wrong here.
The error I'm receiving is this:
ln09{}: perl uses_Mod.pl
Can't locate object method "new" via package "myMod" (perhaps you forgot to
load "myMod"?) at uses_Mod.pl line 11.
I believe that I've done everything I should do to "load" the module, and can't
make it work properly.
The lines of code which "load" the module in my caller are these:
use lib 'Mod';
use Mod::myMod;
The line of code where I get the error is this:
my $obj = myMod->new();
My best guess is that my directory structure is wrong, and the caller simply
can't find the module. Here are the details of that:
ln09{}: ls -l
total 8
drwxr-xr-x 2 travis engr 4096 Jul 9 21:10 Mod
-rwxr-xr-x 1 travis engr 122 Jul 9 21:05 uses_Mod.pl
ln09{}: ls -l Mod
total 4
-rw-r--r-- 1 travis engr 456 Jul 9 21:10 myMod.pm
Can someone take a look at my files below and comment on anything obvious that
I'm not seeing?
Here are the files:
[File: ./uses_Mod.pl]
#!/usr/bin/perl
use strict;
use warnings;
use lib 'Mod';
use Mod::myMod;
my $obj = myMod->new(); # <----- THIS IS THE LINE THAT ERRORS
$obj->myModFunc();
[end uses_Mod.pl]
[File: ./Mod/myMod.pm]
package Mod::myMod;
use strict;
use warnings;
require Exporter;
our @ISA = qw(Exporter);
our @EXPORT = qw(new myModFunc);
sub new
{
my $class = shift;
my $self = {};
# Just so the constructor does something I can see and verify.
$self->{'time_created'} = time();
print STDOUT "Object created at " . $self->{'time_created'} . "\n";
bless ( $self, $class );
return $self;
}
sub myModFunc
{
my $self = shift;
print "myModFunc called\n";
}
1;
[end myMod.pm]
