Hi,
I am facing problems while I try to compile a simple "Hello
World" Kernel module. I am using RHEL 5 (2.6.12.x kernel).
This is the program that I am trying to compile.
/************************* Hello World Kernel Module
*********************/ #define MODULE #define LINUX #define __KERNEL__
#include <linux/module.h> /* Needed by all modules */ #include
<linux/kernel.h> /* Needed for KERN_ALERT */
int init_module(void)
{
printk("<1>Hello world 1.\n");
// A non 0 return means init_module failed; module can't be loaded.
return 0;
}
void cleanup_module(void)
{
printk(KERN_ALERT "Goodbye world 1.\n"); }
MODULE_LICENSE("GPL");
/*************************** End of the Module
***************************/
The make file that I am using is
/************************* Hello World Makefile
*************************/
obj-m += hello-1.o
all:
make -C /lib/modules/$(shell uname -r)/build M=$(PWD) modules
clean:
make -C /lib/modules/$(shell uname -r)/build M=$(PWD) clean
/*************************** End of the Makefile *******************/
The error that I am getting is that
"/lib/modules/$(shell uname -r)/build cannot be found" or something like
that.
I did find the "/lib/modules/$(shell uname -r)/build", but there was
nothing in it. I am facing this only when I try this with RHEL 5 or FC
7.
Thank you,
Regards,,
Aravind.
