Consider the following two classes: Base and Derived.
The complete code is as follows:
//Base.h
class Base
{
public:
void showBase();
};
//Base.c++
inline void
Base::showBase()
{
std::cout << "This is the base class.";
}
//Derived.h
class Derived : public Base
{
public:
void showDerived();
};
//Derived.c++
void
Derived::showDerived()
{
std::cout << "This is derived class.\n";
std::cout << "Calling base class method.\n";
Base::showBase();
}
//InlineTest.c++
int main()
{
Derived derived;
derived.showDerived();
return 0;
}
Command-line : g++ InlineText.c++ Base.c++ Derived.c++ -o Inline.o
Compiler error output: /tmp/ccDKDhFN.o: In function `Derived::showDerived()':
Derived.c++:(.text+0x32): undefined reference to `Base::showBase()'
