I'm newbie at driver module programming.... I've written a very simple hello world module then I wanna compile it , I got this result :
Code:
make -C /lib/modules/2.6.38-8-generic/build M=/root/ker modules
make[1]: Entering directory `/usr/src/linux-headers-2.6.38-8-generic'
make[1]: Makefile: No such file or directory
make[1]: *** No rule to make target `Makefile'. Stop.
make[1]: Leaving directory `/usr/src/linux-headers-2.6.38-8-generic'
make: *** [all] Error 2
Also I've installed linux headers via following command
Code:
apt-get install linux-headers-2.6.38-8-generic
here is my Makefile file
Code:
obj-m += hello.o
all:
make -C /lib/modules/$(shell uname -r)/build M=$(shell pwd) modules
clean:
make -C /lib/modules/$(shell uname -r)/build M=$(shell pwd) clean
Also I gotta note that , the "build" is not exist at that folder
my source code :
Code:
#include <linux/module.h>
#include <linux/kernel.h>
int init_module(void)
{
printk(KERN_INFO "init_module() called\n");
return 0;
}
void cleanup_module(void)
{
printk(KERN_INFO "cleanup_module() called\n");
}
thanks
