Answer 1

undefined reference is a linker error, indicating the linker could not find implementation for the specific method.

try to add a implementation for you foo constructor in foo.h

virtual ~Foo();
Foo();
bool foo(void) { return true; }

To

virtual ~Foo();
Foo() {} //add default implementation
bool foo(void) { return true; }
