Template specialization for an empty parameter pack

Question

I have a variadic template function which calls itself to determine the largest number in a list (constituted by the templatized arguments). I am trying to make a specializa

Answer 1

I see two mistakes using clang.

1. Put the overload taking a single int first.

2. Make things unambiguous for lists of length 1. Recall that variadic lists can have zero size and when they do, it seems to me you have an ambiguity.

This compiles and runs correctly for me:

#include 

using namespace std;

template 
int tmax() {
    return N;
}

template 
int tmax() {
    return N > tmax() ? N : tmax();
}

int main() {
    cout << tmax<32, 43, 54, 12, 23, 34>();
}

54
