Problem description

I'm trying to write some text to the screen, but it feels like no matter what I do i always get:

Failed to load font "../assets/Font.ttf" (failed to create the font face)

A very simple example of the code.

#include<SFML/Graphics.hpp>

int main()
{
    sf::Font font;
    font.loadFromFile("../assets/Font.ttf");
    
    sf::RenderWindow window(sf::VideoMode(800, 600), "SFML works!");
    sf::Text text("Hello World", font, 50);

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

    return 0;
}

I'm building using Cmake and I expect that the problem lies in my CMakeLists files. I have one main and a sub-directory like: (Also very simple)

#Main

cmake_minimum_required(VERSION 3.0)
project(Sorting_Visualization)

add_subdirectory(src)

# Sub Directory

add_executable(${PROJECT_NAME} main.cpp)

find_package(SFML 2.5 COMPONENTS graphics audio REQUIRED)
target_link_libraries(${PROJECT_NAME} sfml-graphics sfml-audio)

File structure:

.
├── assets
│   └── Font.ttf
├── CMakeLists.txt
└── src
    ├── CMakeLists.txt
    └── main.cpp

What I've tried

I read that similar problems occurred when people using Visual Studio linked release libs to their debug builds. There was suggested to link with ex. sfml-graphics-d for debug libs. However this doesn't seem to work for me and using dpkg libsfml-dev I don't see any files matching sfml-graphics-d. Should I maybe install these in some way?. Or is that some Visual Studio specific issue?

Further I think I was missing the Freetype dependecy at the time of installing SFML however running ldd on my sfml-graphics.so file it seem that freetype is found.

libfreetype.so.6 => /lib/x86_64-linux-gnu/libfreetype.so.6 (0x00007f26fdca0000)

Lastly I was thinking that maybe the font I'm using is simply not compatible. But surely any true type font should be possible to use. Here is a link the font.

To summarize

I think I've read nearly everything there is online and I'm still completely stumped. The only thing left is my linking in Cmake which I found no clear resources on and I'm pretty new to working with libs. Some guidence would be greatly appreciated on this : )

Solution

I solved the problem and it was apparently the order in which I was finding the packages and linking them. I also have to always make all

This is working!

set(SOURCES main.cpp)

add_executable(${PROJECT_NAME} ${SOURCES})

find_package(SFML 2.5 COMPONENTS REQUIRED audio graphics )
target_link_libraries(${PROJECT_NAME} sfml-audio sfml-graphics)
