Hi all,

I'm getting the following errors when trying to build my project. Has anyone got any idea what is causing the "multiple definition of vtable/typeinfo" errors, and how I can fix it?

The code is a bit complex to post here, but basically I have a class called "Fixture", containing a boost::gregorian::date and two std::strings, and a class called "Result" which derives from "Fixture" and adds two ints. "Fixture" has no virtual functions.

The error occurs if I add a line which assigns the address of an object of type "Result" to a pointer-to-"Fixture", ie:

Result test1 (date(2004,10,8), "Home Team", "Away Team", 5, 3)
Fixture* pTest2 = 0;

pTest2 = &test1;

Any info would be very welcome.

Kind Regards,

Ian
