ifneq($(KERNELRELEASE),)
 obj-m:=helloworld.o
else
 KDIR:= /lib/modules/2.6.33.3-85.fc13.i686/build
all:
 make -C $(KDIR) M=         


        

Answer 1

There must be a space between ifneq and (.

The TAB prefix means that it is a shell command, so be sure that the shell commands (make and rm) begin with TAB, and all other lines such as ifneq do not begin with TAB.
