my source code for parse sip frag like this:

//subscription can be ended through a notify or a failure response.
void TSipAccount::onTerminated(ClientSubscriptionHandle h, const SipMessage* msg)
{
       
    if (msg != NULL && msg->exists(resip::h_Event) && msg->header(resip::h_Event).value() == "refer")
    {
        const Mime sipfrag_t("message", "sipfrag");
        int reason = 0;
        if (msg->exists(resip::h_ContentType) && msg->header(resip::h_ContentType) == sipfrag_t)
        {
            SipFrag frag(msg->getContents()->getBodyData(), msg->header(resip::h_ContentType));
            const SipMessage &fmsg = frag.message();
            if (!fmsg.isRequest())
            {
                reason = fmsg.header(h_StatusLine).statusCode();
   
            }
        }
       }
}


this compile is ok, but got link error, I found the constructor of SipFrag I used declared in SipFrag.hxx, but not implemented in SipFrag.cxx

so can anybody help to find out how to parse sipfrag?
