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

Hi, I’m getting a strange error 'Invalid value for shared scalar' when I try do run one code like this: 
use threads;
use threads::shared;

my %Inventory;
my %Test;

share ( %Inventory );

$Test{0}{0} = 1;
$Test{0}{1} = 1;
$Test{1}{0} = 1;
$Test{1}{1} = 1;

%Inventory = %Test;

If I remove the share function, it's running well, but I need to share the hash on threads and don't figure out way this happen.

Thanks

Re: Error on assigning shared hash

    You missed this part of perlthrtut:
    In the case of a shared array, all the array's elements are shared,
and for a shared hash, all the keys and values are shared.
This places restrictions on what may be assigned to shared
array and hash elements:
only simple values or references to shared variables are
allowed - this is so that a private variable can't
accidentally become shared. A bad assignment will cause
the thread to die.

    Your hash values are neither simple nor shared.

      Runrig, thank you so much... I'm re-reading the perlthrtut to check this litle details.
