while I ecounter the problem like "error: expected declaration specifiers or ‘…’ before ‘size_t’" as following :

make: *** [module.o] Error 1
—————————————————————————————————————————-
and my makefile (under Ubuntu system) is :
—————————————————————————————————————————-
SRC =module.c
OBJC_M =module.o
CC =gcc
CFLAG=-DMODULE -D__KERNEL__ -O2
INCLUDE=/usr/src/linux-headers-2.6.22-14/include
$(OBJC_M):$(SRC)
$(CC) $(CFLAG) -I$(INCLUDE) -c $(SRC) $(OBJC)
clean:
rm -f *.o
—————————————————————————————————————————-
so I change the INCLUDE form
INCLUDE=/usr/src/linux-headers-2.6.22-14/include
to
INCLUDE=/usr/src/linux-headers-2.6.22-14-generic/include
—————————————————————————————————————————-
then solve the problem above ,like "expected declaration specifiers or ‘…’ before ‘size_t’"
