hi, i have a question

first i have this object
iObexBufData = CBufFlat::NewL(KBufferSize);
iObexBufObject = CObexBufObject::NewL(iObexBufData);

and the declaration is:
CBufFlat* iObexBufData;
CObexBufObject* iObexBufObject;

and then i add this to the declaration
CBufBase* dataBufronald;

why adding
dataBufronald = iObexBufObject->DataBuf();
to the code cause an error like this:

OBJECTEXCHANGECLIENT.obj : error LNK2001: unresolved external symbol "public: class CBufBase * __thiscall CObexBufObject:ataBuf(void)" (?DataBuf@CObexBufObject@@QAEPAVCBufBase@@XZ)
