Graphics / SfRenderWindow leak

« on: January 11, 2021, 05:04:36 pm »

Hi, this might a bit of a classic one but when using valgrind on my small CSFML program I get 3 fat leaks at exit time despite using sfRenderWindow_destroy(). sfRenderWindow_close() does not change anything and so does free().

It says that leaks come from libsfml-window.so which I don't understand because I link with -lcsfml-window and not -lsfml-window since my whole program is in C.

Maybe there's something I just don't get with CSFML because some sfThreads send some leaks as well despite using sfThread_destroy().

Here is my valgrind output:

Is there a way I don't know to cleanly exit my program or should I just ignore these?

(btw sorry if this is in the wrong forum but sfRenderWindow is part of the graphics lib not the window one so I don't know)
