Kompilator zwraca mi błąd:
| Code: |
[Linker Error] undefined reference to `IMG_Load(char const*)'
ld returned 1 exit status
C:\Dev-Cpp\Kurs okienka\Tenis\Makefile.win [Build Error] exe: *** [Plapluś.exe] Error 1 |
Do wiersza poleceń konsolidatora dodałem:
| Code: |
-mwindows

../png/sdlDevCPP-1.2.4/lib/libSDLmain.a
-luser32

Proszę o pomoc.

bez SDL polskie znaki działają, a po usunięciu polskich znaków kompilator zwraca to samo

Najprawdopodobniej potrzebujesz dolinkować dodatkową bibliotekę: libSDL_image.a
Pozdrawiam,

Co prawda nie używałem SDLa w WinApi ale zdaje mi się że brakuje tu "IMG_INIT_PNG". Ponadto gdy odwoływałem się do Surface'a do którego wczytałem plik instrukcją IMG_Load to też wywalało błąd. Wtedy robiłem tak:
| Code: |
SDL_Surface *wczytaj;
SDL_Surface *obrazek;
wczytaj = IMG_Load("obrzek.png");
obrazek = SDL_DisplayFormat(wczytaj);
SDL_FreeSurface(wczytaj); |
I wszystko działało.

Zapomniałem dopisać że do działania potrzebny mi był plik "libpng12-0.dll". Albo spróbuj zapisać samo IMG_INIT. No i na końcu dodaj instrukcję IMG_Quit()

To jedynym sensownym wytłumaczeniem jest brak jakiegoś pliku, o czym wcześniej już ktoś pisał.
