The following code generate a compilation error:
class Foo {
private:
Foo() { }
};
class Bar : public Foo
{
public:
Bar() {}
};
int main()
{
return 0;
}
however,commenting out "Bar(){}" (i.e. let the compiler generate one for me),do
not cause any compilation error.
the same case for virtual base constructor(in which I discover it when reading
C++ faq 23.9)
class FooBase
{
friend class Foo;
private:
FooBase();
};
class Foo : virtual private FooBase
{
public:
Foo() { }
};
class Bar : private virtual Foo
{
public:
Bar() {} //no error if comment it out
};
int main()
{
return 0;
}
test on gcc 3.3 and gcc 3.4 in debian:
