I have code that looks like this:
template <int Rows>
struct A {
std::array<int, Rows*Rows> array;
template <int X, int Y>
int at(int x, int y) const {
return array[X*x + Y*y];
}
};
template <int Dim>
struct B {
void dosomething(A<Dim> value) {
auto x = value.at<0, 0>(0, 0);
}
};
The compiler (gcc 6.3 and clang 3.9) complain about the line
auto x = value.at<0, 0>(0, 0);
with error: expected unqualified-id before numeric constant
I guess I have some ambiguity here, but I can't figure out how to resolve it. Also it is important that A and B are templates otherwise the error doesn't show up.
Some help and hints about what the compiler is really complaining about and how it could be fixed would be great.
