 Posted: Sat Sep 02, 2006 7:36 am Post subject: Inizializing SDL |
 |
|
Alright, im trying to code using SDL, ill admit, im just trying to learn these things but whenver I try to use anything from SDL_mixer and SDL_image, it doesnt compile and just has errors...I initialized both using this code:
| Code: | /* Initialize SDL */
if ( SDL_Init(SDL_INIT_VIDEO|SDL_INIT_AUDIO|SDL_INIT_JOYSTICK) < 0 ) {
fprintf(stderr, "Couldn't initialize SDL: %s\n",SDL_GetError());
return EXIT_FAILURE;
}
|
and , yeah its still having errors stating..
| Quote: | | Undefined Reference to 'IMG_load' |
and ect.
how can i verify I set up SDL_image and SDL_mixer properly?
thanks,
psiko |

alright after a bit more tweaking, i realized that its now complaining about OGG files. I thought that if you installed LibTremor you didnt need to install OGG....eh, ill just get em all then right?
any suggestions? |

You have to link your app with -lvorbisidec or something I think.
I've done that to try and play vorbis through SDL_mixer BTW but it simply didn't work. As in, did nothing. Compiled, linked, ran but didn't play the music...
If you get it to work please tell me what you did in the SDL/SDL_mixer/Tremor compiling process :)

alright i got a majority of it to compile without errors...
but im now im getting a PNG error!!!
here is my Makefile, i think thats where my problem lies.
| Code: | TARGET = template
OBJS = main.o
INCDIR =
CFLAGS = -O2 -G0 -Wall
CXXFLAGS = $(CFLAGS) -fno-exceptions -fno-rtti
ASFLAGS = $(CFLAGS)
LIBDIR =
LIBS = -lstdc++ -lc -lSDLmain -lSDL_ttf -lSDL_mixer -lvorbisidec -lSDL_gfx -lSDL_image -lz -lpng -lgl -ljpeg
LDFLAGS =
EXTRA_TARGETS = EBOOT.PBP
PSP_EBOOT_TITLE = Template
PSPBIN = $(PSPSDK)/../bin
CFLAGS += `$(PSPBIN)/sdl-config --cflags`
LIBS += `$(PSPBIN)/sdl-config --libs`
PSPSDK=$(shell psp-config --pspsdk-path)
include $(PSPSDK)/lib/build.mak
|
maybe im doing something wrong?
i followed the directions on this page:
http://feonix.dommel.be/eng%20tuts/translate01.htm

SDL_image.
i dont quite know what yet. |

Would you by any chance have installed libPNG, LibJPG, LIBSDL_TTF, LIB GL?
If not download and install them from svn |

ok, i changed a few things around. Its still not compling. It keeps stating that there are errors with LibPNG.
I have installed all the libs (not too sure about libGL) but everything else Ive installed. I think my problems are stemming from SDL_image.
I installed them all like i said using the website as a basis. Maybe I installed them wrong? is there anyway to un-install them?
lol
