Sorry, i wrote this code at night and but I tested it in 2018.
I make video with this problem
I haven't touched this code since 2018 and this problem still exists.

I started learning SFML in 2018 and when i learn sfml, i noticed this.
if you declare sf::RenderWindow in the library and try to pass a pointer sf::Drawable or reference you get this error.

regardless of static or dynamic linking.

testSF.dll

class TestSF
{
    sf::RenderWindow window
public:
    TestSF();


    sf::RenderWindow* getWindow();
    void draw(sf::Drawable *drawable);
}


TestSF()
    : window(sf::VideoMode(600,400), "Test")
{


}


sf::RenderWindow* TestSF::getWindow()
{
    return &window;
}


void TestSF::draw(sf::Drawable *drawable)
{
    sf::Event event;
    while (window.pollEvent(event))
    {
         if (event.type == sf::Event::Closed)
             window.close();
    }
    window.clear();
    window.draw(*drawable);
    window.display();
}
 

test.exe

#include <SFML/Graphics.hpp>
#include <testsf.hpp>

int main(void)
{
    TestSF test; // ok
    sf::RenderWindow *window = test.getWindow(); // ok
   
    sf::CircleShape shape(100.f); // ok
    shape.setFillColor(sf::Color::Green); //ok
   
    while (window->isOpen()) // ok
    {
        test.draw(shape); // error here
    }
}
 

but if i add sf::Context in main function the error disappears.

test.exe

#include <SFML/Graphics.hpp>
#include <testsf.hpp>

int main(void)
{
    sf::ContextSettings settings;
    sf::Context ctx(settings, 600, 400);
    TestSF test; // ok
    sf::RenderWindow *window = test.getWindow(); // ok
   
    sf::CircleShape shape(100.f); // ok
    shape.setFillColor(sf::Color::Green); //ok
   
    while (window->isOpen()) // ok
    {
        test.draw(shape); // ok
    }
}
