Base class inaccessible due to ambiguity

[daniel.w.gelder]

Well, I can't seem to make a class from two bases just because they
have the same virtual function, even though I'm specifying the exact
function:

struct A
{ virtual void Function(); }
struct B
{ virtual void Function(); }

struct C : A, B
{
virtual void Function()
{
A::Function();
B::Function();
}
};

I didnt know this was not kosher but it is a pickle. Any way around
this?

Thanks
Dan

Hmm, this works for me.

Compiler: g++ (GCC) 3.3.4 (pre 3.3.5 20040809)
OS: Linux, SuSE Pro v9.2

// z.cpp
// to compile: g++ -o z z.cpp
// to execute: ./z
#include <iostream>

struct A
{
virtual void Function()
{
std::cout << "A.Function()" << std::endl;
}
};

struct B
{
virtual void Function()
{
std::cout << "B.Function()" << std::endl;
}
};

struct C : A, B
{
virtual void Function()
{
std::cout << "C.Function()" << std::endl;
A::Function();
B::Function();
}
};

int main()
{
C c;
c.Function();

return 0;
}

Larry,

I compiled the code I supplied and it worked for me too which means the
problem is being triggered elsewhere but the error message is showing
up in the struct definition. gcc can be annoying sometimes. Thanks

Start at the line number per the error message and look at
previous lines for a missing brace, comma, or semi-colon.

struct A
{
}

is not a struct, but the following is:

struct A
{
};

the following is a struct A with a declared but non-implemented member
function called Function:

struct A
{
void Function();
};

The following does implement Function()...

struct A
{
void Function()
{
// whatever
}
};
