C2064 term does not evaluate to a function taking 1 arguments

I am currently working on Advent of Code day 2 and I am trying out some different stuff for the first time. I heard about boost split through a podcast while on the road and immediately wanted to give it a go when I got home.

I have my vector games as the output, the input gameSets, and the delimiter ;.
I was hoping to print each element within games to the console to ensure my elements were correct.

#include <iostream>
#include <fstream>
#include <string>
#include <boost/algorithm/string.hpp>
#include <vector>

vector<std::string> games;

void partOneAnswer() {

    // Open File
    std::string filePath = "test_values.txt";
    std::ifstream stream(filePath);
    std::string line;

    if (stream.is_open()) {
        while (std::getline(stream, line)) {

            // printf("%s\n", line.c_str());
            std::string delimiter = ":";
            std::string gameSets = line.substr(line.find(delimiter) + 2, line.length());
            //printf("%s\n", gameSets.c_str());

            while (gameSets != "") {
                // place each set into a vector, being delimited by ;
                boost::split(games, gameSets, ";");
                for (int i = 0; i < games.size(); i++) {
                    std::cout << games[i] + "\n";
                }
            }
        }
    }
}

The result was the error.
Any ideas on why?

Error takes me to:

\boost\algorithm\string\detail\finder.hpp 578

Compiling was not an issue until I added boost.

>Solution :

boost::split needs a predicate for its delimiter, you can’t use a string:

boost::split(games, gameSets, boost::is_any_of(";"))
