Unresolved symbol when inheriting interface
- by LeopardSkinPillBoxHat
It's late at night here and I'm going crazy trying to solve a linker error.
If I have the following abstract interface:
class IArpPacketBuilder
{
public:
IArpPacketBuilder(const DslPortId& aPortId);
virtual ~IArpPacketBuilder();
// Other abstract (pure virtual methods) here...
};
and I instantiate it like this:
class DummyArpPacketBuilder
: public IArpPacketBuilder
{
public:
DummyArpPacketBuilder(const DslPortId& aPortId)
: IArpPacketBuilder(aPortId) {}
~DummyArpPacketBuilder() {}
};
why am I getting the following error when linking?
Unresolved symbol references:
IArpPacketBuilder::IArpPacketBuilder(DslPortId const&):
ppc603_vxworks/_arpPacketQueue.o
IArpPacketBuilder::~IArpPacketBuilder():
ppc603_vxworks/_arpPacketQueue.o
typeinfo for IArpPacketBuilder:
ppc603_vxworks/_arpPacketQueue.o
*** Error code 1
IArpPacketBuilder is an abstract interface, so as long as I define the constructors and destructions in the concrete (derived) interface, I should be fine, no? Well it appears not.
