Error when compiling "test"

[U3-Robot]

Why kgsws's test file for MOHH exploit (from sdk folder) not compiling? I only modified main.c to load mp3 file. I also included audio libs in the makefile (wrong?) and write includes in sdk.h.

BUT I GET MANY ERRORS:

It is a long time since i dont program to PSP, but those are linker errors.
The only libs that you are linking in your makefile are -lpspaudio and-lpspmp3. I believe that there are more to you add in LIBS to compile and PSP project, because the compiler didnt found the implementations of basic functions like "sprintf" ,"sceUtilityLoadModule" and so on.

Now I have that libs: LIBS = -lpspgu -lpng -lz -lm -lpspaudio -lpspmp3

But it still doesn't work.

Btw, I am registered on this forums, ONLY because kgsws registered here too and he can help me. So.
