Hi. I’ve done a very very small change in the example program of lesson 3 of Yeldarb but it doesn’t work (the original works fine ) if someone helps me I'll be very grateful ;) : 
ERROR:

						problem (newbee)
sorry I've repear it but stil 1 error.

I have put it like this but I dont know if it is there where I must put it: 
TARGET = lprg
OBJS = main.o
CFLAGS = -O2 -G0 -Wall -lpsphprm_driver
CXXFLAGS = $(CFLAGS) -fno-exceptions -fno-rtti
ASFLAGS = $(CFLAGS)
EXTRA_TARGETS = EBOOT.PBP
PSP_EBOOT_TITLE = lprg
PSPSDK=$(shell psp-config --pspsdk-path)
include $(PSPSDK)/lib/build.mak
even so...I still have this error:
...undefined reference to: 'sceHprmIsRemoteExist'
...undefined reference to: 'sceHprmPeekCurrentKey'
 
Sorry for been soy silly XD and tedious ...
