Undefined reference to `oslIsWlanPowerOn'

Question

I am developing a PSP homebrew application and I using the makefile from the exampel but it won't link because the stupid (excuse my French) linker says that oslIsWlanPowrOn is undefined. I know I am linking the right library, plus I am following an example so it should compile. I know most stackoverflow users don't use the oslib or do much psp programming but any help would be appreciated. I have also tried reordering the order of the libs but still states the same linker errors. Anyhow here is the code below:

Makefile

TARGET = main
OBJS = main.o

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


LIBS= -lpspwlan -losl -lpng -lz -lpspnet \
         -lpsphprm -lpspsdk -lpspctrl -lpsprtc -lpsppower -lpspgu -lpspgum  -lpspaudiolib -lpspaudio  \
         -lpspnet_adhocmatching -lpspnet_adhoc -lpspnet_adhocctl -lm -ljpeg 

LDFLAGS =
EXTRA_TARGETS = EBOOT.PBP
PSP_EBOOT_TITLE = PSP Chat
#PSP_EBOOT_ICON = ICON0.PNG
PSPSDK=$(shell psp-config --pspsdk-path)
include $(PSPSDK)/lib/build.mak

There was a problem with the installation of the sdk and so I reinstalled it. Voila--it worked. Thanks for everyone who tried to diagnose the problem.
