Troubleshooting

If you're having problems making nim-csfml work, the most likely cause is incorrectly installed dependencies. The message such as could not load: libcsfml-graphics.so does not necessarily mean that the library was not found; maybe CSFML just doesn't work (possibly because SFML is missing). So first make sure that you can run the following C program:

#include <SFML/Window.h>

int main() {
    sfVideoMode mode = {800, 600, 32};
    sfWindow* window = sfWindow_create(mode, "CSFML works!", sfDefaultStyle, NULL);
    while (sfWindow_isOpen(window)) {
        sfEvent event;
        while (sfWindow_pollEvent(window, &event)) {
            if (event.type == sfEvtClosed)
                sfWindow_close(window);
        }
        sfWindow_display(window);
    }
    sfWindow_destroy(window);
    return 0;
}

Compile with gcc -lcsfml-window -lcsfml-system main.c or same with clang.

One of the typical problems is incompatible versions of SFML and CSFML. CSFML lags behind with updates, so you may need to get an older matching version of SFML.
