SFML-无法加载图像-无法打开文件-LINUX

Question

Description of problem

I was developing my project on ubuntu (clion ide) but I changed distribution to xubuntu and cloned the same repository to it. Unfortunately, each image which I include in project generate this runtime error:

Failed to load image "image.png". Reason: Unable to open file

SFML is installed correctly because I checked it with standard program from SFML Site . I didn't have that problem on ubuntu.

My try

I think that there is a problem with permissions of files. So I create sample project (as below), added player.png and I get the same error. So I use that command in terminal:

chmod a+w player.png

It doesn't solve a problem. I am new in linux so maybe there is something more to do, but I don't know. I also tried different ways from this site and SFML forum but it doesn't helps me.
I also tried to load other images, doesn't work too.

Code

There is sample code which I have created to find problem. It is only modified sample from SFML Site .

#include <SFML/Graphics.hpp>

int main()
{
    sf::RenderWindow window(sf::VideoMode(400, 400), "SFML works!");
    sf::Texture t;
    t.loadFromFile("player.png");
    sf::Sprite sprite;
    sprite.setTexture(t);

    while (window.isOpen())
    {
        sf::Event event;
        while (window.pollEvent(event))
        {
            if (event.type == sf::Event::Closed)
                window.close();
        }

        window.clear();
        window.draw(sprite);
        window.display();
    }
    return 0;
}

Solution and another problem:

What is interesting,

    t.loadFromFile("../player.png");

solved the problem. By default, sfml expected the image to be in cmake-build-debug folder...
How to add default directory to my project, not to cmake folder?

Answer 1

You are looking for an option to change your current working directory. This can be done either using CLion or CMake.

Take a look at this question where you can find answers which describe both ways.
