SFML、C++、Makefile - 无效指令

问：

我正在使用 SFML 用 C++ 编写一个 Arkanoid。事实是，当游戏结束时，游戏的状态会从游戏的状态变为残局。游戏状态发生变化，在控制台上输入游戏记录，但不是几毫秒，并输入以下内容：make： *** [Makefile：19： all] 无效指令（已创建内存转储）。

若要运行代码，可以使用以下命令：make

操作系统 ： Archlinux

Pkg 版本：make 4.4.1-2、sfml 2.6.0-3

游戏.cpp ：

#include "../include/Game.hpp"

Game::Game()
{
    initWindow();
    initFont();
    currentState = std::make_unique<GameState>(window, font);
}

void Game::initWindow()
{
    window.create(VideoMode(SCREEN_WIDTH, SCREEN_HEIGHT), "Arkanoid");
    window.setFramerateLimit(60);
}

void Game::initFont()
{
    if (!font.loadFromFile("fonts/mont_extralightdemo.ttf"))
        exit(0);
}

void Game::changeState(std::unique_ptr<State> newState)
{
    currentState = std::move(newState);
}

void Game::handleInput()
{
    currentState->handleInput();
}

void Game::update()
{
    currentState->update();

    if (currentState->isGameOver()) {
        int score = currentState->getScore();
        std::unique_ptr<State> newState = std::make_unique<EndGameState>(window, font, score);
        changeState(std::move(newState));
    }
}

void Game::render()
{
    window.clear();
    currentState->render(window);
    window.display();
}

我以为问题出在文本输出中，但我删除了这个变量，没有任何改变......(
