Ĺadny brzuch
Może ktoś spotkał sie z tem problemem kiedyś, otóż kiedy uruchamiam program z poziomu edytora widze formatke z czarnym ekranem(powinno wczytac grafiki z katalogu i blitowac je na formatke), natomiast kiedy uruchamiam ten sam program z katalogu problem nie wystepuje. Dodam że wszystko kompiluje sie bez błedów. Aplikacja to prosty program w sdl'u.

Na 95% SDL nie znajduje szukanych plików bmp i dla tego ich nie wyświetla. Posprawdzaj dokładnie ścieżki.
