Hello everybody,

I'm a beginner with coding in c/c++ and i'm doing a lot of tutorials and try to load music and images in an homebrew. I've made this but i get an error when i compile it. Someone else tried to help me, but it doesn't helped me. please can someone here help me, i'd really like to load an image AND a music(on the background without controls). TY in advance.

I didn't look at your code, but to fix the compiling errors add -lpng -lz and -lpspgu to the LIBS line in your Makefile.

[JoRDozZzz]

OK Thanks for your comment.
I've done that and now it's like this:

TARGET = mp3foto
OBJS = mp3player.o main.o graphics.o framebuffer.o

CFLAGS = -O2 -G0 -Wall
CXXFLAGS = $(CFLAGS) -fno-exceptions -fno-rtti
ASFLAGS = $(CFLAGS)
LIBDIR =

LIBS = -lmad -lpspaudiolib -lpspaudio -lpsppower -lpng -lz -lpspgu
LDFLAGS =

EXTRA_TARGETS = EBOOT.PBP
PSP_EBOOT_TITLE = MP3 Player by Pspuser

PSPSDK=$(shell psp-config --pspsdk-path)
include $(PSPSDK)/lib/build.mak

Thanks, now i don't have ALL those errors. But i still have some errors. This is my error right now:

[Insert_witty_name]

Add -lm to the end of the LIBS line.

[JoRDozZzz]

Insert_witty_name your the best of the world. compiling is done. i've started the homebrew, but displaying the image and listening to music didn't work, so there is something wrong in de main.c source. But i'm going to ask friends to help me with the source, but compiling is now available to say so ;)

thanks you very very much for help. PS2Dev.org Forums are the best forums to ask things about coding and developing i see. on other forums i still have no reactions :(

when my homebrew is completed i'll post it here with thanks to Insert_witty_name.

// greetzzzz
