I'm trying to stop a capture thread from another thread breaking the $capobjects loop, for that I need to share that variable, but it fails with the share: thread failed to start: Invalid value for shared scalar at test.pl line 22. (open_live line) 
use threads;
use threads::shared;
use Net::Pcap;
my $capobj:shared = ();
my $capthread = threads->new(\&capture);
sleep 3;
Net::Pcap::breakloop($capobj);

sub capture {


        my $err;
        my $dev = Net::Pcap::lookupdev(\&err);
        my ($address,$netmask);
        Net::Pcap::lookupnet($dev,\$address,\$netmask,\$err);
        my $filter;

        $capobj = Net::Pcap::open_live($dev,1024,0,0,\$err);
        Net::Pcap::compile($capobj,\$filter,'host XX.XX.XX.XX && port 
+7777 && udp',1,$netmask);
        Net::Pcap::setfilter($capobj,$filter);
        Net::Pcap::loop($capobj,0,\&capture_callback, 0);
        Net::Pcap::close($capobj);

}
sub capture_callback { .... }
