Graphics / Drawing sf::Text results in a crash"writing_system_class" was nullptr

« on: September 07, 2021, 06:06:45 pm »

Hello,

I'm looking for some advice on how to use sf::Text object. Specifically what is causing this crash to occur from Freetype library. Right now, any attempts to draw sf::Text results in a crash. I have included a link to my source code below as well as screenshots that showcase my setup after a build/crash. I am running 64-bit Windows with vcpkg as my main source of pulling in dependencies. I'm more than certain I am using debug libraries for a DEBUG build as vs code cmake tools sets by default.

My Source Code
https://github.com/obscurelyme/hello-sfml/blob/ed15963b38b896e414fab1b811ac5c8c7918e92d/main.cpp#L53-L73

Code Snippet:

// Load fonts
    std::string executableDirectory = std::filesystem::weakly_canonical(std::filesystem::path(argv[0])).parent_path().string();
    std::string relativeFontFile = "/assets/fonts/Roboto/Roboto-Regular.ttf";
    std::string fontFilePath = executableDirectory.append(relativeFontFile);
    sf::Font font;
    if (!font.loadFromFile(fontFilePath))
    {
        spdlog::debug("Could not load Roboto-Regular.ttf from directory {}", fontFilePath);
    }
    else
    {
        spdlog::debug("Successfully loaded {} font-family.", font.getInfo().family);
    }

    sf::Text text{"Hello", font, 48};
    text.setFillColor(sf::Color::Red);
    text.setStyle(sf::Text::Regular);
    text.setPosition(200, 200);
    ...
    while(running) {
       sf::Event event;
       while(window.pollEvent(event)) {
           // handle event[s] ...
       }

       window.clear(sf::Color::Blue);

        window.draw(text); // program crashes when this is called.

        window.display();
    }
 

Here is the screenshot of the crash in debugger
