I am trying to put the hardware playing portion of lightmp3 into a standalone library which I can use in other homebrew applications. When I try to compile I get these errors:
| Code: | psp-gcc -I. -I/usr/local/pspdev/psp/sdk/include -O2 -G0 -Wall -D_PSP_FW_VERSION=
150 -c -o mp3playerME.o mp3playerME.c

make: *** [alsample.elf] Error 1 |
Here is my make file:
| Code: | TARGET = alsample
OBJS = mp3playerME.o clock.o id3.o player.o main.o
INCDIR =
CFLAGS = -O2 -G0 -Wall
CXXFLAGS = $(CFLAGS) -fno-exceptions -fno-rtti
ASFLAGS = $(CFLAGS)
LIBDIR =
LDFLAGS =
LIBS = -lpspaudiolib -lpsppower -lpspmpeg -lpspaudiocodec -lpspaudio -lm -lstdc++ -lmad
EXTRA_TARGETS = EBOOT.PBP
PSP_EBOOT_TITLE = Audiolib Wave Generator
PSPSDK=$(shell psp-config --pspsdk-path)
include $(PSPSDK)/lib/build.mak |
Right now it isn't a library but it will be. I recently upgraded my toolchain with the latest SVN release and I searched the forums. Any ideas? |

if it's not in the pspsdk library, it's probably in a .S file in the lightmp3 source. You'd just add it to your objects, and if it has a header, use that, else you forgot to include something.

i believe those 3 indefined references refer to these 3 functions you'll have to figure out which is which, which shouldn't be difficult since they all have different prototypes
int sceAudioSRCChReserve(int samplecount, int freq, int channels);
int sceAudioSRCChRelease(void);
int sceAudioSRCOutputBlocking(int vol, void *buf); |

I was trying to compile a version of it from more than a year ago and my SDK is now recent. I fixed the problems.
Here is the solution for anyone who has the same problem:
| Code: | sceAudio_38553111 is now sceAudioSRCChReserve
sceAudio_5C37C0AE is now sceAudioSRCChRelease
sceAudio_E0727056 is now sceAudioSRCOutputBlocking |
Thanks for the help guys. |
