[Opalvoip-devel] Unresolved error - PIPSocket::Close

[J.C M. <jc...@gm...>]

Good day Opal team,

I get the following errors when i compile a simple application derived from
the H323plus sample application;

------
Error    6    error LNK2019: unresolved external symbol "public: virtual
bool __thiscall PIPSocket::Close(void)" (?Close@PIPSocket@@UAE_NXZ)
referenced in function "public: virtual bool __thiscall

..\h323plusd.lib(h46018_h225.obj)

Error    8    error LNK2001: unresolved external symbol "public: virtual

Error    9    error LNK2001: unresolved external symbol "public: virtual

I'm using the latest head version of both ptlib and h323plust.

When tracing the error, i came upon the following code snippet in
winsock.cxx;

----

#if P_QWAVE
PBoolean PIPSocket::Close()
{
  if (IsOpen() && PWinSock::GetInstance().m_hQoS != NULL && m_qosFlowId !=
0) {
    QOSRemoveSocketFromFlow(PWinSock::GetInstance().m_hQoS, os_handle,
m_qosFlowId, 0);
    m_qosFlowId = 0;
  }

  return PSocket::Close();
}
#endif // P_QWAV

------

I managed to find the PIPSocket class in ipsock.h and it had no definition
of the 'Close' function. I even looked in the PSocket class from which
PIPSocket is derived from and I didn't see any definition of the 'Close'
function in there either except in the PChannel class.

The first error is due to the following code from h323plus;

PBoolean H46019MultiplexSocket::Close()
{
    if (m_subSocket)
        return m_subSocket->Close();

    return PUDPSocket::Close();
}

Where H46019MultiplexSocket is basically derived from PUDPSocket and so
forth.

I'm just curious to know if there's something that i've missed or that i
may be looking in the wrong places.

I'm working with Win7 VS 2013 Express edition.

Much appreciate your help.

Thanks,

Josh
