[Click] Problem compiling a new element

[Eddie Kohler]

Ramanathan,

Your elements.conf file reports that your element is using the name  
ReplicateElement.  So I don't know why you say it doesn't work.  Or  
are you trying to change the name to Replicate as in your sample.hh  
file?

There are a number of problems with your code as well.  You cannot  
push a packet twice, as your ReplicateElement does.  You need to  
clone it once

void ReplicateElement::push(int port, Packet *p)
{
    output(0).push(p->clone());   // should really check for errors
    output(1).push(p);
}

And as people point out Tee does this job just fine.  So...?
Eddie
