//We have a code at

https://github.com/arunbalaji91/Linux-Firewall-Exploration-/blob/master/Lodable%20Kernel%20Module%20and%20Netfilter

named rules.c, when I tried to makefile it on Linux, below error shows up, can anyone debug this for me? The rules.c program should be correct, can we somehow turn off the warnning check?

//The code shouldn't be a problem and I was using "make" command to make a file named "Makefile" containing code below:

obj-m +=rules.o

all:

make -C /lib/modules/$(shell uname -r)/build/ M=/home/seed/firewall_prog modules

make -C /lib/modules/$(shell uname -r)/build/ M=/home/seed/firewall_prog clean
