我不知道为什么我不断收到此链接器错误，因为我链接了正确的库，除非我链接了错误的库，否则我确信这一点，但也许有人知道哪个库是函数 SonyOskGu 的正确库。错误是：main.c:(.text+0x134): undefined reference to `SonyOskGu(char*, unsigned int, char*, char*, int)'。代码如下：

#include <psposk.h>
#include "atoi.h"
PSP_MODULE_INFO("OSLib Sample", 0, 1, 1);
PSP_MAIN_THREAD_ATTR(THREAD_ATTR_USER | THREAD_ATTR_VFPU);
#define printf oslPrintf
#define ERROR_SUCCESS 0
#define ERROR -1;
int main(void)
{
    oslInit(0);
    oslInitGfx(OSL_PF_8888, 0);
    oslInitConsole();
    oslInitAudio();
    printf("Press Any Key To Start OSK In Order To Enter Path Of Audio File To Play Audio:");
    char* path = (char*)malloc(255);
    SonyOskGu(path,0xff918f8c,0,0,100);
    printf("The path is");
    OSL_SOUND* sound = oslLoadSoundFile(path, OSL_FMT_NONE);
    if (sound == NULL){
        oslAssert(sound == NULL);
        oslEndGfx();
        oslQuit();
        return ERROR;
    }
    else
    {
        printf("Press X To Play Or Press O To Stop!");
        int key = oslWaitKey();
        if (key == OSL_KEY_CROSS)
        {
            oslPlaySound(sound, 0);
        }
        else if (key == OSL_KEY_CIRCLE)
        {
            oslStopSound(sound);
        }
    }
    oslEndGfx();
    oslQuit();
    return ERROR_SUCCESS;
}

生成文件如下：

TARGET = test
OBJS = main.o  

INCDIR = 
CFLAGS = -G4 -Wall -O2 
CXXFLAGS = $(CFLAGS) -fno-exceptions -fno-rtti
ASFLAGS = $(CFLAGS)

LIBDIR =
LDFLAGS =
STDLIBS= -losl -lpng -lz \
  -lpspsdk -lpspctrl -lpspumd -lpsprtc -lpsppower -lpspgu -lpspaudiolib -lpspaudio -lm -lpsposk -lpspgum -lpspgu -lpng -lz 
LIBS=$(STDLIBS)$(YOURLIBS) 


EXTRA_TARGETS = EBOOT.PBP
PSP_EBOOT_TITLE = PSP Audio Player
PSP_EBOOT_ICON = ICON0.png

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