Initializer list woes

Okay. So what I'm trying to do here is pass a number of string objects as function parameters but (love my skills) I messed up with initializer_list. Big time.

  void print_string (vector <string> vec)
{
...
}

print_string ({"...", "Some more", ... "As many as wanted"});


But apparently I cannot convert an initializer list to a vector. Even if I use auto, I cannot get the program to work. Any workarounds? Thanks.

This works as expected:

#include <iostream>

#include <vector>

void print_strings( std::vector<std::string> vec )
{
    for( const auto& str : vec ) std::cout << str << " -> " ;
    std::cout << ".\n" ;
}

int main()
{
    print_strings( { "pass", "an", "initializer", "list", "where", "a", "vector", "is", "expected" } ) ;
}

The error says that:

Cannot convert <brace enclosed initializer list> to std::vector
It would appear that you need to upgrade the compiler/library to a more current version.
