Microsoft's documentation states that "LNK2019 can occur when a declaration exists in a header file, but no matching definition is implemented. For member functions or static data members, the implementation must include the class scope selector." So, it looks like there's a FlexSim::Map::~Map(void) defined in the header somewhere, but no implementation?

Could you provide more information like what you're implementing and where you're implementing it? Thank you.

The DLL Maker can only access a limited set of types and functions. The Variant class and Map class are not accessible from the DLL Maker.

If you use the Module SDK, you can access both those classes, as well as many others.
